Config a 2620 for voip

[mannin32]

I hope someone has done this before since I can't figure it out. I have a 2620 with a dual T-1 modual and then (2) eithernet moduals. What I would like to do is configure 1 of the T-1 ports to deliver a signal for a phone system as if it were coming directly from the ISP, and have those signals sent out on eth(0) to over the internet to our VOIP provider to send the call to the PSTN. I don't even know if this is possable but I was told by our VOIP provider that we can do this. Please let me know if you think this is logical or not. I don't know how to configure the router to take the eth wan link and send it to the T-1 and vicea versa. I have v 12.2 on the router right now.

Well now I am thinking it is a 2621 since it has 2 built in ethernet ports, and there is a dual T-1 modual

A T-1 moduale is not a T-1 module. You have channelized T-1 modules (for voice T-1s and Voice PRIs) and then you have WAN T-1s for data. And then you have combinations of the two. More than likely, your 2621 has 2 data T-1s on it and thus cannot connect to a phone system in traditional methods. You will need a Mutiflex VWIC or a HD-VM with T-1 cards in it. You got anything of these?


It is what it is!!

Correction

HD-VM = NM-HDV

Yeah I guess I should have been more specific about what I was using, I have the 2 ethernet ports and I have the VWIC 2MFT for the (2) T-1 interfaces. Now I've been reading about what I am trying to do and I found a lot of stuff saying it is possable but I haven't found out how to do it, any help here?

Even though you have the VWIC module, you don't have any DSP resources, so you need a NM-HDV or you have to purchase the AIM module for the 2600 series routers.. I'm not sure if you need the XM versions or not to do the AIM VOIP..

I am not totally familiar with the 2600 series, but I do know you need DSPs. I am not sure if you have any (do a sh ver and it should say something about DSPs being installed if any are detected. You must have IP Plus or better feature set for this). Withou DSPs, the router cannot convert the signal.


I would then suggest you break this down into part.

Step 1)
Get the T-1 signalling working between the 2600 and the PBX.

Step 2)
Set up your dial peers for the VoIP provider.

Have you found a VoIP provider? There is a lot to consider when using VoIP outside your LAN. Many things can go wrong, and many things can effect the quality of the voice. Most providers have not developed a solution for this (except cable companies because it never leaves thier LAN) because too much can go wrong and they will loose business.

We have Net2Phone come in 3 years ago and try this with us. The refused to use a Cisco solution and believe me, it never worked. I did, however, get a nice 3640 router out of the deal and a PRI card for my PBX.

Do some searching on Cisco's website.

http://www.cisco.com/en/US/products/hw/routers/ps259/ps4832/index.html

These explain how to hook up the 2621 to different PBXs. Don't worry about the call manager stuff, the router configs should be basically the same for the serial interfaces. The only thing that will be different is the dial peers.

Okay I checked it out and it looks like there might not be a DSP in this box, here is what I have for hardware installed.

2 Ethernet interfaces
24 Serial network interfaces
2 Channelized T1/PRI ports

Also is there a way to use > like in dos? I wanted to export the whole version information

 

[computerhighguy]

You will be unable to use this for voice until you DSP resources. Frankly, they are quite expensive. I was a 1751-v on ebay for something like 1200 bucks. It's a pretty good deal and come with everything you need. Is this your mail router for your data? If so, I would suggest that you get a second router for your voice network, if the $$ is available.

You cannot use the DOS pipe (>) in Cisco. Cisco IOS is a unix or linux derivative. You can cut and paste from the screen or have Hyperterminal output to a file.

There is a learning curve for the voice stuff. It took me a while to figure out everything I need to make it work. But once I got familiar with the hardware, it is pretty easy to get up and running. Tweaking on the other hand, takes time, practice and lot of reading. This is good stuff to know. It looks impressive on a resume.

Well we got it to work yesterday, it's amazing the quality is just as good as real POTS lines. I didn't figure out the programming we had some telco techs working on it. But this is great when you can get it to work.
