Hello all!

i have CUCM 11.5, expressway c&e x8.9.

Now i have cofiguration MRA for external registred Jabber clients, it work.

I will need configuration B2B calls with external partners.

I reads document "Mobile and Remote Access via Cisco Expressway Deployment Guide (X8.9) ".

On page 51 have information about "SIP trunks cucm between expressway-c", but this information is not enough to understand how it work.

Same in documents have link:
"See Cisco TelePresence Cisco Unified Communications Manager with Expressway (SIP Trunk) Deployment Guide for more information about configuring a SIP trunk."

If i click this link and have result:
Restricted File or Application - Error 403.

Where can I find this document? and where can I find more information about the implementation of B2B calls?

Hi There,

This is the link for the "Cisco Expressway SIP Trunk to Unified CM" Deployment Guide
http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-8/Cisco-Expressway-SIP-Trunk-to-Unified-CM-Deployment-Guide-CUCM-8-9-10-11-and-X8-8.pdf
It is for version X8.8 but X8.9 configuration should be the same.

A really good resource for configuration examples is the Cisco Validated Design Guides (CVD). The guide takes you through the configurations required step by step.

Here is the CVD for Collaboration Edge and B2B.
