SIP URI B2B Calls via CUCM and Expressway

[Igor Gaydarov]

Hi all, 

Can't figure out how to configure SIP URI calls from/to SX codecs, registered on CUCM. 

I have CUCM and IM&P 10.5.1, a pair of Expressways X8.5.2 with two traversal zones - for B2B calls and the external jabber. 

I want to make calls from SX-codecs to the ouside via SIP, using the domain URI, for instance, user1@externaldomain.ru or XXXX@externaldomain.ru. How can I configure that? 

I've already got the route pattern, which matches the SIP Trunk for Exp-C, for H323 calls by ip-address. Is it possible to make a route pattern to call the SIP URI? 

You can see my deployment in this picture. 

Best wishes,

Igor
