has anyone here played around with uploading compatible audio files for custom rings and MOH and/or personalized backgrounds for the phones? I was only taught the basics in our CUCM v6.0.1 and am looking to figure out how to get some good music on my phone as well as play around with other "cosmetic" features. The phone I'm testing with is a 7971(color).
View 4 RepliesI am looking for a Best Practices or a few places to pay attention to in the Cisco ESW-520-48P switch I have. My VoIP solution is RingCentral, and while they are Cisco phones, I've been hestitant to setup VLANs etc. the way I am used to. Plus setting up Auto QoS seems different than what I am used to with a 3750 switch.
Right now I've left the Smartports Wizard alone, and none of the ports are configured. There are no VLANs or QoS on the LAN currently.
What I was running into were calls cutting out where one side wouldn't hear the other anymore, but the call would remain connected. However, this has happened in this small 15 person office, when there is only one employee here after hours, talking on the phone. There isn't any heavy network traffic, because I have network monitoring showing me low usage (no streaming music, videos, or anything else).
This switch has a Gb connection to a Linksys SR2024 (the server switch), which is also set at Factory Defaults. I mention that because I recently bypassed the ESW-520-48P, and plugged one phone into that switch and the RingCentral phone worked fine for outside calls.
Is there something besides QoS that I should look at in the ESW-520 switch that might be causing a checkpoint of some sort, or interrupting VoIP traffic that I need to configure or disable?
And are there any Best Practices or scenario guides for this switch? I found the Admin Guide, but it really just explains every option in the GUI for the switch. And it seems all of my CCNA training isn't working with going in and quickly troubleshooting this switch besides knowing that something in it could be hanging it up.
I have some 79xx series VOIP phones that are acting VERY strange ... if you are familiar with these series phones once plug them into the PoE switch they look for a TFTP server with the call manager files to acquire all the info they need to work .... i have them set up on a 2620xm router running IOS c2600-ipvoicek9-mz.124-15.T14 along with call manger 4.3. My router is my TFTP server and i have hooked up and fixed over 50 of the same series phones with out a problem.
Now here is my issue ... when you goto press the SETTINGS button on the phone you are allowed to go into the settings of the phone to change all the ROUTER,TFTP,ETC info to allow you to connect your phone to the CALL MANAGER or you can set up DHCP and it will acquire the info automatically. When i press the SETTINGS button nothing happens .... i can reset the phone to factory defaults by holding the # button then 12345678*0# then 2 not saving the info and i can hit the restart buttons which is * 6 SETTINGS buttons together and that will let me restart the phone but i cannot manually set up this phone to do anything .. it will not acquire info form my DHCP server and will not find my TFTP server at all =( the phone SETTINGS BUTTON does not respond at all ..only when restarting the phone.
I have an SRP547W hooked up as the office router with the standard office phones connected via the telephone ports at the back of the unit using 2 SIP lines as well as the PSTN by dialling hash first. We have just added a new staff member and bought an SPA303 with the intention of connecting it through registered SIP lines on the SRP547W, and hopefully have the facility to use the PSTN line when the SIP lines are busy.
The problem is, it connects to VLAN100 and gets its IP address and initializes fine however no lines show as configured and it can't make or receive calls. What do I need to configure on the SPA303 to tell it to use the SRP547W as its SIP Server/Proxy (not sure of the terminology).
A couple of users on my network complain about timeouts. They access the same server which runs a SQL server. People from outside world can access it without a problem but internally it keeps timing out. I have also noticed that VoIP phones have a delay internally. So if i pickup my phone and dial an extension the other person can't hear me sometimes but i can hear him.
I have experienced the VoIP problem but have never had any time outs on my machine. I tried packet capture on a couple of computers but i cant see anything out of the ordinary. Alot of ARP, some STP which i think shouldn't reach the machines, dropbox traffic etc.
I purchased Linksys WAG160N (from a store) and I also have 7 Linksys SPA962 VOIP phones provided by MyNetPhone with service included. All tests we found out that this modem doesn't work with this VOIP phones. Somehow probably doesn't give access to MyNetPhone servers to get connection with this phones.I purchased an other one from DLINK and works perfect?

View 0 Replies View RelatedAll of our VoIP phones bounced (re-registered) in the middle of the work day and we do not know why. There is no maintenance going on at this time. The phones came back up right away. Upon further investigation, I only found one error message on our core switch (WS-6509 running IOS ver. 12.2(18)SXF13) and I'm wondering if that was the cause:
Jan 3 13:51:04.030: %SIBYTE-SP-5-SB_OUT_OF_RX_DSCR_CH1: Out of RX descriptors on mac 0 - channel 1 (count: 299)

I am new to VLANs although I generally understand the concept. I have a small office with 25 desktop/laptops and 15 VoIP phones connected with a SG200-50 switch and on Port 1 I have the Cisco SRP541W router for DHCP and Internet access. My goal is simple: 1) Segregate the VoIP phones (voice) from the computers (data) and 2) Prioritize the VoIP phones traffic.
I believe this can be accomplished by setting up a second VLAN and maybe a third (if the default should not be used) and then identifying those ports as Voice VLAN ports. I guess I just need to know how to flag each interface and each port so that they all can talk to the router on Port 1 yet the voice and data will be in different broadcast domains. Also, do I need a management VLAN??
Is this setup correct? VLAN 1 - default (data) Port 1 (Trunk) (Tagged)Port 2 - 30 (Access) (Untagged)VLAN 2 - voice Port 1 (Trunk) (Tagged)Port 31 - 48 (Access) (Untagged) What should the interface settings be on each port (General, Access or Trunk)? What should the port VLAN membership be on each port (Tagged or Untagged)??
I have a CUCM BE environment with a number of remote users with 8961 phones connecting to an ASA 5501 via AnyConnect. The phones register fine and can make inbound/outbound calls as well as four digit dialing to other users at the corporate site.
The problem is when a remote user tries to four digit dial another remote phone. The called phone will ring but there is dead air once answered and then the line goes dead.
This sounds like a routing issue to me. How to get AnyConnect clients to be able to reach each other?

So I've been checking my router DHCP list and I usually use the WPS feature to add devices. I know how many devices I have and which ones are wireless etc. I've made address reservations on all the devices that I have and know of. One feature that really frustrates me (which is missing) is no way to rename a device. My iPhone is named: Reggie's iPhone yet the 4300 picks it up as Unknown... I dont understand why. I've renamed it on the iPhone to different things and restarted it but still it comes up as that. I have 2 Nexus 7s and both come up with wierd names, one is for my wife and one is for me and I wish there was a way to name it proper.
Question is: Will the name edit feature ever get added to it? I dont get why it's not there now, it's not really something major (I have a 5 year old router that even has that... and it cant even support N). It's really frustrating to have to guess and check the devices on my network because most of them come up as unknowns.
Right now I'm trying to located another device that's coming up as unknown and now matter how much I try, since the router lacks any feature to assist finding it, it's really frustrating.
something else i noticed: my DHCP List shows all the devices connected with their IP addresses, yet I went into CMD and was doing a random ping command. I'm able to ping 192.168.0.114 with perfect stats back yet on my DHCP List it shows the highest IP is at 192.168.0.112.... Is something wrong here? Is it supposed to not pick up the IPs it gives out? And of course since there isnt a way to tell if that IP is for a WIFI or ethernet device, I have no idea what that device is...
yet i found another ip address on my network by using the ping command. actually I went ahead and did arp -a to find out all the ips with mac addresses. this is a serious flaw with the security of this router!!
I'm planning to use 2 3560X (access switch) on two different locations connected over two 2921 routers in small ring. 3560Xs are directly connected via fiber. Each 3560X is conected to its own 2921, and 2921s are connected together with GRE over IPSec. So they are creating ring.I'm planning to use small area 0 in this scenario. There are less then 200 routes in the network. Will 12.2(55) IP Base on 3560X support this scenario or I will need IP Services image? "OSPF for routed access" is still little vague to me, there are only tipical case study scenarios.
View 22 Replies View RelatedI've looked in many places but cannot see how or if it is possible to configure a phone, in CUCM to have a feature ring instead of the normal ring.In CUCME you go into the ephone x configuration mode, and assign the DN to the phone with the button xfx command. What this gives you is a slightly different ring tone when a call comes through. If I am not mistaken it is the same ringtone they use on the show "24".Is there a way to do this "feature" with CUCM?

View 3 Replies View RelatedI need to setup a layer 2 network consisting of 14 switches interconnected in a ring. Obviously, the design of 14 switches in a ring network is dumb, not here to debate that. Unfortunately, it HAS to be a ring. I've been researching the best way to configure RSTP for this. From everything I've read all I really need to do is configure Primary/Secondary root bridge in the center, and change the Maximum Age field to at least 16 seconds? From what I've read you want a minimum of 3 second buffer + 1 second for each hop due to message age being added by each switch hop?
View 8 Replies View RelatedI´ve got a strange problem with the connectivity within a ring topology.There are five switches from the SGE2000 series and one SG200-50.The SG200-50 is the root bridge and RSTP is configured.From the root bridge switch (Switch 5) I can ping Switch 0.But I cannot ping Switch 0 from PC0.
On the other hand I am able to ping all other Switches (1-5) from PC0.In addition to that I can establish a RDP connection from PC0 to Server0.This tells me that there is no general problem with the connection from PC0 to the Switch0.
Right now when I want to configure Switch0 the only way is to connect to Server0 first.But we have to move Server0 and this is why I want to manage Switch0 from PC0 like any other Switch on that network.
In the Dual ring network using the token passing method, we have the primary ring and the secondary one where in the normal situation only the primary ring is carrying the token in one direction and when this ring is down the secondary will start into operation and takes the token and rotate in the inverse direction of the primary to reach its destination. Why the secondary ring doesn't continue in the same direction to the destination?
View 10 Replies View RelatedMy topology is a physical ring, and I need transfer IPTV signal to all site along the ring.For example:
A (headend)--- B --- C --- D
|______________________|
Note: -----: have spoke-mesh defination
_____: no spoke-mesh defination to prevent loop
So, with MPLS/VPLS I can implement it. With spoke and mesh defination, the traffic can transfer form A to B, C or D as drop-continute action in ring topology (between different VC). Everything is good, FRR can work very fast. But when the topology have a failure link, for example the link between B and C, at that time the traffic will go from A to B then B come back to A and A --- D ---C. This action is so stupid, because it can increase delay, jiiter in network. On the other hand, when the node failure ( B failure), C will loss the IPTV signal, even the link from A--D--C always good.

I have a new install with 3 SF300 switches, setup as vlan 2, the switch connected directly to the 2901 router has no problems, plug in a phone and it gets an IP, but if connected to either of the two swtiches behind the first switch, they do not get an IP.

why our PBX system would freeze up the phones. There is no real reason why this happens. We have the PBX on its own circuit board, so its not sharing any power, we only have about 200 phones on the system, so that is not the issues. Its properly cooled. It just seems to happen that our phones freeze, and when they start freezing it seems to happen in pairs.

If the 8000 phones are reset the network BW could be come a real mess. Besides the CM could hang with so many tftp downloads.

View 3 Replies View RelatedI am working in Private IT company. The facility is having 4000 users and it is a high resliency site having two core switches and nearly 40 access switches. All core and access switches are 4506E switches and odd vlan is taking core-1 and even vlan is core-2. We are having cisco ip phones 6921 connected as daisy chain.( Phone is connected to access switch and the desktop is connected to ip phones). The Ip phone are getting registered cisco call maneger server. The call manager one leg is connected to one core switch and another one is core 2 same like my DHCP server.
For all vlans the the default gateway is my firwall. The voice needs to hit the call manager, hence we have implemented a source routing to call manager for the voice vlans. the problem is once we down the Core-1 some of the IP phones are not getting registered no matterit is on odd or even vlan. The same issue for Core-2. We suspect that there might be some issue in the DHCP server for voice vlan routing. But server team is saying that there is no issue with the DHCP server.Now network is vulnerable that if any core switch is down my voice ip phones will be down.
I have some Catalyst 3560 PoE switches running the latest 12.2(50)SE1 image. I have a working configuration for STP, QoS, Voice & Access VLANs, Port-Security & IGMP snooping - I stress this is working PERFECTLY. Now I have been playing with wired 802.1x port authentication for a while which again I have sucessfully deployed on ports without IP Phones. I did some more testing with 802.1x clients behind some Cisco IP Phones and after understanding the issues and workarounds I thought I had a working environment. The environment is XP SP3 with the new separate wired 802.1x supplicant, workstations are all in a 2003 AD Domain and the wired 802.1x settings are configured through group policy. I had issues with Windows Server 2003 SP2 not working behind IP Phones but this I put down to the supplicant being different from the new one in XP SP3. MS don't have any plans for Server 2003 SP3 (or XP x64 SP3?) nor can I find any hotfixes to resolve this so it's a 'caveat'.Anyway I have tested this many times and with XP SP3 and the new supplicant it all seems to work well (only the access VLAN is using 802.1x Authentication, I am not authenticating the IP Phones via 802.1x).
Now today it stopped working and 802.1x clients behind the 7970 IP Phones no longer authenticate. I have spent an hour or so looking at this and the IOS is the same, as is the configuration on the IAS (Radius) server, as are the XP clients. I was scratching my head a bit and then looked at the IP Phone - the software on the phone has been upgraded to 8.5(2) - previously it was 8.4(4). I managed tp downgrade the software via CUCM to 8.4(4) and it now works. I have retested it several times so this is obviously an issue (either a new feature or a bug?) with the latest code for the 7970. I have checked and it's the same codebase for all the latest IP Phones - 7906, 7911, 7931, 7941, 7942, 7945, 7961, 7962, 7965, 7970, 7971 & 7975 which was released on 1st June. I have looked through the release notes and EAP-FAST has been added but this is an update to the EAP supplicant on the phone and not a feature of the 802.1x pass-thru from the attached device. I can find no other 802.1x or EAP references.
