Configuring e1 r2 on a Cisco 3845 voice gateway

Hello,

I want to configure e1 r2 on my cisco 3845 voice gateway. The e1 r2 will be used only for outgoing calls. Do you have sample configuration for my requirement.

Thank you.

There is a lot of info on CCO, eg:

http://cisco.com/en/US/products/sw/iosswrel/ps1834/products_feature_guide09186a00800e9760.html

My personal suggestion: make sure that:

1. you use a very recent image. Like 12.4(11)T1.

2. your telco has made extremely clear to you what are the configuration parameters they expect, and are willing to collaborate.

3. that in the worst case, you are entitled to open a case with Cisco TAC.

E1/R2 is not like ISDN where when things don't work are easy to diagnose and fix. It is a legacy signaling protocol with his own quirks and requires technicians to have a solid understanding of the way it works.
