Wireless Phone --> 881W router --> VPN --> ASA5510 --> LAN with CCM and Voice Gateway
Phone registers to CCM Internal calls work External calls connect but get no voice in either direction
We have installed a SRST in one of our remote offices. They have ISDN Primary, and we have a 6mb MPLS link to our main HQ with 400k of QoS on the line. During the day, both Internal calls over the MPLS and external calls over the ISDN break up, but it doesnt happen all the time, i.e in a day the morning will be ok, then the users experience the break ups in the afternoon, then its everything is ok again.
The only factor that the calls share is the Lan infrastructure i.e the 3750G switches (7) of them which are stacked.We did have MAC flapping errors, and our telecoms provider suggested that it maybe these causing the issues, however we have got rid of all MAC flap errors, and are still receiving voice break ups.
Because the Lan switches are the only "item" both calls share, I am wondering now if the setup of the switches is correct. [code]
is it possible to setup a Cisco ISR 881W so it connects to a Cisco ASA 5500 series head via network extension mode? We did this in the past with our PIX connecting to 3000 series concentrator.

My company has an 881-w ISR that provides wireless and wired network functions for our small office (about 20 users). I was attempting to create a new V LAN (another story), and was able to create the V LAN (4) and assign it a new IP. However, when i came in today, and when i attempted to connect to the ISR, the serial console started spewing this over and over:
*Feb 8 13:31:32.479: %SYS-2-MALLOCFAIL: Memory allocation of 8 bytes failed from 0x81528DF0, alignment 0

Now, I did leave the console session up overnight, as that's the only thing that I can think of. As expected, our service contract had expired. I did reboot the ISR, and I am looking to see if this can be fixed, or symptomatic of a larger issue, and time to replace? At this point i can't even get it to stop, and thus cannot log in.
We're looking at implementing a new phone system which will use voice over ip. Currently we have a mixture of Cisco 3750 and Cisco 3550 switches which don't support power over ethernet. Its been suggested we could continue using the current switches and power the new phones using power adapters.
Int terms of implementing qos (we don't have any at the moment) for the voice will a Cisco 3550 be OK and will having a mixture of different models using 3550 and 3750 pose any challenges with the qos policy for the voice. I believe there are differences in that the Cisco 3550 doesn't support srr-queues but having little experience with qos I'm not sure what impact this will have if any?
I have a customer who has a Cisco 2821 router with software 2821/HSEC/K9 and they wish to upgrade to C2821-VSEC-SRST/K9.From my understanding they want to use the same router but install an IOS with the capabilites it has at the moment but with voice. [code]How do I go about pricing this up and what upgrade sku's will do this?I am not to worried about the memory.Is it just a simple ios upgrade as the srst licenses are on a trust basis?

I have had a couple of customer complaining about voice quality and our voice team spent a lot of time investigating; I had ruled out the network infrastructure because it was all QOS enabled. The voip people came up against a blank so I looked at the network once more and disbaled dbl with hope more than anything else. Mysteriously the voice quality issues the customer was having have now disappeared. Not sure whether a coincidence (though I have done this on two customers now) or something to with with dbl. There is nothing on this on cco.

I have spent several days tearing my hair out trying to properly configure our small business switch (SG300-10p) for voice. The phones are a relatively new addition and will replace old POTS phones.Our network consists of a 1941 ISR router, the SG300-10P switch, a mac server (handing DHCP, DNS, AFP), 4 client desktops and 4 SGA525G2 IP phones. The router, server, desktops and phones all have their own connection to the switch and the second data ports on the back of the IP phones are not used. We do not have any unified comms devices for voice. Our VOIP solution is hosted by a local SIP provider, and each phone independently registers with the provider's SIP proxy over the internet.
Left almost to it’s own devices (or presumably flat, default settings on VLAN 1), this whole setup works just great. We can TFTP files, make and receive calls, and do all the usual XML stuff. Calls are crystal clear. Even the localisation and directory works. However, I’ve been told several times that to ensure good quality on VOIP calls during periods of busy traffic, I should set up some form of QoS. A Voice VLAN on the switch, I was told, is the best way to do this as it automagically gives priority to the whole voice VLAN over the normal data VLAN.
I have followed instructions in numerous manuals, articles and guides, and have managed to create the Voice VLAN, both manually and automatically (I can watch Smartport detect the phones and see the Auto Voice VLAN add the ports to the VLAN as I connect them). The trouble is, as soon as this happens, the phones lose connectivity with the rest of the network, including the DNS server and the router, and therefore the internet, causing them to lose registration with the SIP service.
I tried adding the server and router ports to the Voice VLAN and tweaking every possible combination of tagged, untagged, excluded, trunk, access, general and PVID settings I can think of (by the way, I have no idea what any of those mean). The switch is in Layer 2 mode, but adding the port connected to the router to all the VLANs does not result in internet connectivity to the phones. I have told the phones to tag frames with the VLAN ID and told them not to. I have tried upgrading firmware and I have rebooted the switch so many times I'm tired of those wretched little flashing lights.
Nothing seems to work. And so I am stuck with everything on VLAN 1. My most recent thought is that the 1941 needs to know about the Voice VLAN (I checked CDP and it knows about the switch), but I’m reluctant to start messing with the router config when this is our production network, at least without knowing what I'm doing. I don’t even know if QoS applies when a Voice VLAN is not set up and we're on VLAN 1, some articles say yes, others say no. And when it is set up right, how does that priority transfer to the router? I’ve looked in the router manual and config options and found something called 802.1Q, but I have no idea what it is, how it works or even if it applies to our situation. Can I forgo VLANs altogether and use QoS some other way, perhaps?I have googled enough to cobble together our setup in IOS up until now. Ideally, I would still like to be able to ssh or https into each device (as I do now) for management, and I’ve read about setting up a another VLAN for config, monitoring etc, but I guess that would mean routing between VLANs in Layer 3.
If we configure a Voice and Data VLAn on a switch. And connect EX90 on voice VLAN and PCwith EX90 terminals. Than can we able to share a presentation or data with EX90 or not?

View 3 Replies View Relatedim working in a new enviroment and want to makes some design changes to the environment. I wanted to bounce my ideas some of you folks to see if my thinking is on the right path or maybe i could do things better.
Setup:
Currently the setup that i manage includes and Sonic Wall (also dishes out dhcp), HP 1810 "Core Switch" and 3 SG 300-28P cisco managed switches. (all cisco switches tie back into the HP) The router is managed by the isp. There is only one vlan with all traffic going across it.
Obviously the glaring issue here is that voice and data all reside on the same vlan. Correct me if i am thinking incorrectly but the first step would be to create a separate vlan for the phones with its own IP scheme. currently phones are issued addresses from the 150-200 range and everything else is left for pc's, printers etc. To my knowledge the HP switch does layer 3 but i do not know much about it. There are vpn tunnels to remote offices that are used for sharepoint, email and to access other services. Trying to wrap my mind around the environment as a whole so i may be missing something obvious i could do design wise to improve.
For many years we've had the following vlan and port security config on our 3560s: [code] This has worked great on 12.2(37)SE1, 12.2(40)SE and 12.2(46)SE. However since 12.2(50)SE, and I've tried all the versions since then, we have a problem with 7900 phones and ATA186s taking upwards of 20 minutes before they can get a valid IP number.The problem on the newer IOSes seems to be related to the inactivity aging.On the older IOS versions the mac address of the voice device appears on the voice vlan straight away.
On the newer IOS versions the mac address of the voice device appears on the DATA vlan and seems to be stuck there until the inactivity aging removes it. It then gets re-learned, sometimes on the voice vlan, and sometimes on the data vlan. If you're unlucky and it gets re-learned on the data vlan you've got to wait until the inactivity time ages the address out again. Repeat until the mac address eventually gets learned on the voice vlan. I don't want to be stuck on 12.2(46)SE forever.
I have to configure router 2811 for Data and Voice network.However I have only one Fast Ethernet interface. [code]
what else do I need to configure on switchport on which Avaya phones are connected.And is there any extra command, i need to configure on the router and 2950 switch.
We have two MPLS circuits managed by two different suppliers, one carries VOICE the other DATAWe are to decommision the VOICE MPLS and have increased the bandwith of the DATA MPLS to carry VoIP traffic too.
At both of our sites A & B ,devices connected to the LAN have a default gateway of the VOICE providers Cisco 2600 router , which then goes into the LAN switching. (see diagram)So what I am trying to achieve is toto simply replace these 2600 routers from the VOICE MPLS provider with our own so we dont have to change the default gateways at both sites.
Testing
Our Cisco 2600 routes are plugged into each LAN switching environment with two subinterfaces configured, one for voip and the other for dataThe problem is from the router and respective subinterfaces we can get to the other sites destination without any issue, but if for example a user is at site A with Ip address 10.16.11.12/16 they cant ping the VOIP subnet at site B 10.3.11.0/24. But If a ping is issue from the Site A test router then the 10.3.11.0/24 subnet is reachable but only on the 10.3.12.0/24 configured subinterface.So i guess what Im saying is 10.16.0.0/16 from the LAN needs to be able to get to 10.3.11.0/24Note at site A 10.16.0.0/16 & 10.3.12.0/24 can communicate no problem and at site B 10.207.0.0/16 & 10.3.11.0/24 can communicate no problem.We are using IP routing, should we be using route-maps?
I am trying to write an extended ACL for the voice vlan.My scenario is the following:I have two PBXs with two Catalyst 4505 L3 switches.The C4505 are connected trough a trunk link.I have a VTP domain configured.
Voice VLANs are Vlan 100 and Vlan 101 with networks 10.2.0.0/16 and 10.4.0.0/16 Voip telephones are communicating between them self and everything is working fine.I want to secure both voice VLANs with an ACL to allow only couple of IPs to administer the phones.The PCs are connected trough a integrated switch via VOIP telephone.Here is the sample configuration of the dhcp pool for the PC VLAN:
ip dhcp pool PCs
network 10.1.0.0 255.255.0.0
default-router 10.1.1.1
dns-server 10.10.10.1
option 43 hex 010a.5369.656d.656e.7300.0000.0204.0000.0064.0000.0000.00ff
I had to implement the 43 hex option because the PCs did not get the ip from the DHCP because of the vendor specific information.The thing that worries me is will the DHCP forward the ACKs for the PCs if I implement this test ACL:
ip access-list extended VLAN100
permit ip 10.2.0.0 0.0.255.255 10.4.0.0 0.0.255.255
permit ip 10.4.0.0 0.0.255.255 10.2.0.0 0.0.255.255
permit ip 192.168.2.0 0.0.0.255 10.2.0.0 0.0.255.255
permit ip 192.168.2.0 0.0.0.255 10.4.0.0 0.0.255.255
permit udp host 0.0.0.0 eq bootpc host 255.255.255.255 eq bootps (this I am not sure do I need)
permit udp host 255.255.255.255 eq bootps host 0.0.0.0 eq bootpc (also this)
deny ip any any
I only want to allow the network 192.168.2.0/24 and maybe some other hosts to access the web based http gui to adiminister the IP phones.All PCs are connected trough the VOIP terminals. I do not want to deny the traffic to PCs.
Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.
