Supporting Multiple Registrars with CME

Hello,

I am attempting to utilize the "Multiple Registrars on SIP Trunks" IOS feature with my Call Manager Express.

http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/sip_cg-multi-registrars.html

I want to register to a BroadSoft via two different Edge Session Border Controllers.

I have configured the two registrars, but I have a problem when those registration methods go out. Since I am registering to a BroadSoft, I need the registering SIP URI to look like this:

REGISTER sip:test.domain:6034

From:4445551212@test.domain

This works fine when I use a single registration. But when I try to use multiple registrations I get:

REGISTER sip: 11.11.11.11:6034

From:4445551212@11.11.11.11

Which the BroadSoft rejects because the SIP URI does not include “test.domain”

Has anyone else had any experience with multiple registrations with BroadSoft? Thanks in advance.

I think you need to change Registrar IPs into domain name , like this...

Router(config-sip-ua)# registrar 1 dns:test.domain:6034 expires 3600

Router(config-sip-ua)# registrar 2 dns:test.domain:6035 expires 3600

Or you can give a try to SIP profile for modify headers..

Thanks for the reply.

My problem is that if put the single test domain in the registrar commands, the CME doesn't know where to sent the registration methods.

I will take a look at the SIP profile.

The SIP profiles did the trick.  But unfortunately that also means I need a CUBE license with the CME...
