Re: quick question about sip and CUBE [In reply to]

Sorry, I forgot an important piece of the puzzle. CUCM will only accept SIP messages for a given SIP Trunk on CUCM nodes that are in the CM Group of the SIP Trunk's Device Pool. For example:

Here are your 3 CUCM nodes in the cluster:
publisher
subscriber-a
subscriber-b

and you create a SIP Trunk, call it "To_UK_CUBE" and put it in a Device Pool with the following CM Group:

subscriber-a
subscriber-b

CUCM will reply with a 503 if you send a SIP INVITE to the publisher from the UK CUBE.

HTH,
-Tom

You don't have to set up multiple listening ports on CUBE, as it's indifferent. On CUCM the two trunks have different source ports. If it's outbound from CUCM only that matters, no CUBE changes are required. If you need inbound calls to have MTP only for certain calls changing the port is the best way.

However, the choice of which of those gateways is basically random and you may think there are two but it's only using one, but that's a H.323 caveat.

Create your two trunks pointing to the CUBE, using respective SIP Trunk security profiles, and that's how you force an inbound trunk.

The require only when needed comes in to play for SIP Early Offer only. And that's a matter of the calling device and whether or not CUCM receives its capabilities or has to make something up using an MTP's capbilities. DTMF relay mismatch (Out of band versus In band) is a different story, and there's no check box for that. That's simply a function of the Media Manager and the MRGL on the SIP trunk, which will correct DTMF mismatches automatically by dynamically using an MTP as needed. So, three different things going on there.
