If you have some clusters with +8000 phones, how would you plan a strategy to upgrade the firmware of all the phones?
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.
The approach is going resetting phones in little sets, like ten phones a time.
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?
I have my ASA configured with Static PAT commands. Currently there are 6 DVR machines in my organization with different IP Addresses 192.168.8.1 - 192.168.8.6 and port used by all DVR is 8000.I have a requirement to make these DVR able on Internet for management purpose. Right now i am using below command for DVR static PAT .Now my query is that how can i use port 8000 with all the Static PAT to be used for DVR Access with different IP addresses.Secondly, when i try to hit http://111.119.x.x:8000 from internet i got error The Page Cannot be delayed.

I had been using a D-link wireless USB adapter with a D-Link wireless router - with no problems, but now when I try to reinstall the usb wireless adapter it asks for a hard wired connection to the router and even then it won't install and will not connect wirelessly or with the network cable. it seems the internal Dell network adapter has been affected in some way and will not work - as you can see I don't have alot of pc savy..?

We have a handfull of miscellaneous issues, across a variety of hardware and customers, and would like to scan through the change logs to see if any of these issues were addressed by a previous bug fix.

View 7 Replies View RelatedI just got a new Asus AC66U. When I play games I have severe stuttering now using the 5Ghz band. I ran a ping to the router and every 20-30 seconds it jumps up from 1ms to 100-900 for 2-4 pings then backs down. I tried running ping test on two computers with the same result.I tried fixing the 5Ghz to a specific channel. I've tried upper channels, lower channels, I've adjusted the channel width from 20-80Mhz. I've changed the preamble from long to short, I've upped the transmit power, I've turned off PnP. I haven't been able to change a setting that made a difference.
I did notice that the lag spikes were much less frequent in the morning when I tested, before everyone was using the internet, although I saw an occasional ping spike. They must be related to router load.i don't want to change the firmware on the router in case I have to return it. I spoke with Newegg and they're going to send me a replacement router. I doubt that it's the hardware, but this will be a good way to know for certain that it's not the hardware. Once I get the new router I'll test everything again including trying the ping with a LAN cable.
I have my dap-1522 connected to my dir-655 in bridge mode. I was having intermitant connection problems with the dap-1522, so I updated the firmware to 1.41 for version A1. Now when I go to change the connection type to dynamic ip and save, it reverts back to static ip, which makes this thing useless for my network. Why won't it save?

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. I am seeing the DHCP request hitting the router, and the router sending the IP to the phone, but it never gets the IP.

All ports are setup as trunk on vlan 2 including the ports that connect the switches together. Not sure what the problem is, but they are going live tomorrow and only have 48 out of 120 phones.
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.

Weird because I have Cisco IP communicator phones that register with no problem. You guys know what I can be missing. I have restarted the CUCM and services multiple times.

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.
PoE works fine with C 1131/1141 Access Points and C-7975 IP phone but PoE does not seem to work on 7960 Phones nor on the C-1121 Access points
All devices work properly with the Cisco power injectors or on a Cisco Cat-29XX switch
Is there a trick to make PoE work for older devices ?
I want to connect a 6911 IP Phone to a SG 300 switch. This is my scenario: vlan 3 data, vlan 9 voice, vlan 10 admin.I have a trunk on port 10 of the SG 300 (vlan 1 untagged, vlan 3,9,10 tagged) and it is connected to a switch 3560, this switch has all the L3 configuration of the vlans and the SG 300 switch has an IP on the admin vlan (10).Also i added the OUI of my IP phones an created an LLDP Policy. Right now I have a 7941 IP Phone working but 6911 is not working. Iam using the new version 1.1.0.73 that supports CDP.
Also I noticed that even when my PC and IP phone receive IP address they can not ping each other nor the SG 300. They only can ping the default gateway or IP addresses in diferent vlans but connected on 3560 switch.
Looks like I still have an issue with LMS to recognize the IP Phones in UT as IP Phones. SNMP RO on Call Manager is enabled and is green in CM (e.g. topology) - so SNMP get is basically fine. The Phones are recognised as End Devices in UT.
As far as I understand, now if I start a Phone Aquisition, the CUCM is polled by LMS to gather additional information about the phones. So it seems there is a problem with the SNMP polling of the Call manager?
I am trying to configure my ACS to allow 802.11 phones to authenticate. I have searched high and low for documentation on doing this with no luck. We are using unified wireless with a mix of 5508 and wism controllers.

View 3 Replies View RelatedI have a question regard to switch SFE2010P, i have 2 vlan ( data and voice) and we want to configure Ip phones SPA502G, the question here is how can i make to suport 2 vlans on the same switch port, like the catalyst IOS switch port acces vlan x and switch port voice vlan x, if i set up the switch with the voice vlan like tagged doesn't work, but if i set up the voice vlan like untagged vlan its works but the PC attached to the data port on the SPA502G doesn't work?
View 1 Replies View RelatedI have 2 (and maybe soon 5 more) 7940G phones to add to my network, which already has a Netgear POE capable switch. I've since discovered that early Cisco POE isn't the same thing as current POE, and the switch doesn't power the phones.
I was looking at adding a Cisco SD208P 8-port switch to power the phones, but I soon discovered it only has 4 POE ports, and I'm not sure that this switch will even power the 7940G phones. And if the other 5 phones show up, I'll need two of those switches with no room for expansion on the voice network.
Will this switch power those phones?Is there another small switch available so I don't have to replace my existing switch infrastructure to get these phones to work? Or do I need to scrap the phones and get something newer that will work with the current POE standards?
We have a Cisco ASA 5520 and use the Cisco VPN Client a lot, but I can't seem to to get Android phones to connect (Ice Cream Sandwich OS), it seems to want use Anyconnect

View 4 Replies View RelatedI 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).
I have a WLC 4402 on my network. Recently mobile phones can connect to the wireless network and obtain a valid IP address. This IP is pingable from a workstation anywhere else on the network. However, these phones will not display web pages. They come up page cannot be displayed. I even tried putting Google's IP address in the phone's browser and it still did not display. I can connect through the same WLAN via a laptop or iPad. These devices have no problem displaying web pages. I even went ahead and created a new TESTWLAN with no encyption but to no avail. Same results: laptops connect and display web pages and smart phones connect, gain IP but do not display web pages. Comes up page cannot be displayed. This matters not whether its an iPhone or Android platform.
