Configuring PRI
Answer
8/8/08 6:13 PM
At the bottom is text from the mailer. Here is how to configure a PRI T1 on IOS.

Regards,
-Chris


PRI is signaling that IOS uses to make or recieve phone calls where it uses 23 T1 channels per T1 card plus one D channel (or data channel).

The D channel is used to send the Caller ID and other information to the in-bound GW. This is called 'out-of-band' signaling. Out-of-band signaling occurs when the data is recieved by IOS via a Data channel.

The following configuration is needed for the PRI T1 controller:

controller T1 6/0
framing esf
linecode b8zs
cablelength short 133
pri-group timeslots 1-24

For each PRI controller, you also need to define an Interface as follows:

interface Serial6/0:23
no ip address
ip mroute-cache
no snmp trap link-status
isdn switch-type primary-5ess
isdn incoming-voice modem
no fair-queue
no cdp enable

When you create the configuration for the controller T1 above, IOS will also create this entry for you. This is the voice port that you will either listen in on or send out calls to:

voice-port 6/0emoticon

Subject: AS5350 config example

Hi,

Can someone please share with me "sh run" of working AS5350XM with CVP (incoming calls via SIP) ?
I need it for a partner that has issues with the configuration

Also - what is the recommended IOS for AS5350 VXML w/CVP (currently running 12.4(20T))

Thanks
Rafi

Hi Rafi,
Please respond here. We are moving people off the mailer to the forums. Your question is very open ended. CVP can be configured with many different deployment models using H323 or SIP. A GW can be Ingress, VXML or both. The recommended configuration for IOS with CVP is in the CVP Config and Admin Guide. We do not publish how to configure T1 lines because they are usually configured by network engineers that work for the partners or customer and CVP is an IVR.

If you have a specific question about certain configurations, I can answer them or I can point to you recommended configuration for CVP. But the configuration is hardware independant. The config applies for all versions of IOS.

What exatly is your issue? Listing a 'show run' would most likely not solve your issue since each GW (outside of CVP config) will be configured differently at each customer depending on the customer's need for that GW.

Regards,
-Chris
