SIP to SIP Trunk with Cisco in middle

SIP to SIP Trunk with Cisco in middle

SIP to SIP Trunk with Cisco in middle


  I have an issue.  I have a sip trunk from a provider that requires that we use a Cisco Gateway, encryption etc.... (fact is there is nothing I can do about it.)  I have a sip based PBX that I wish to pass calls to and from.

  Does someone have an example of how to do this.  I am banging my head on the desk with different permutations of dial peers.

Has anyone made this work before?

provider <== sip ==> cisco gateway <== sip ==> PBX

Thanks in advance.
