Sip trunk between CUCM7.0 and third party VOIP provider

Hi all,

I'm looking for a solution/howto configuration for setting up a SIP trunk between CUCM7.0 and a SIP-VoIP provider.

Got SIP username, password and SIP-proxy IP from the provider.

I've done such a setup on CUCME a couple of times, but never on the CUCM.

Who can put me on right way?

Can it be done on the CUCM, or must an IOS-Device be used (got a PSTN-GW connected through H323 with CUCM)?

THanks for the hint,

Greets Norbert

I would be interested in knowing the answer to this as well.  And if an IOS device must be used, can I ue same IOS device for multiple

SIP trunks either from same provider or different providers?  Thanks in advance for any input.

We are using  CUBE on a 2900 series router. We have two routers to two different destinations for redundancy We are using one SIP providers but exploring a second provider in order to expand.

You will need CUBE if:

* Your provider requires DN registration.

* Your provider wants to see early-offer on the outbound INVITE to them (the majority do, these days).

* Address hiding of your IP phone IPs from the service provider.  (i.e. if you aren't using SIP-NAT somewhere).

Otherwise, peering straight to the CUCM via SIP trunk would be fine.
