Two 2921 Routers

How possible to perform direct call between two VoiP routers, such as I have one office with 2921 CUCME+VOip users and another one office with CUCME 2921+VOip users, how users perform VOIP call between these networks.

In addition to dial-peers add

In addition to dial-peers add the following on both sides:

voice service voip
 allow-connections h323 to h323
 allow-connections h323 to sip
 allow-connections sip to h323
 allow-connections sip to sip

Depending on which protocol you are using SIP vs H323 you may need some of the above.

Thank you Chris.Just one

Thank you Chris.

Just one moment. As far as I understand dial peer trunk between both C2921 with CUCME will be SIP or H323 according to your config? And I should choose one of it. Am I right?

The config I provided would

The config I provided would allow for either, the protocol is driven by the dial-peer configuration, if you have "session protocol sipv2" under the dial-peer then it's SIP, if there is no such line then it's H.323.

configure dial-peers from

configure dial-peers from router to router and back

 

or share your config and I will do
