Limiting Amount of SIP Trunks Used for Outbound Calls?

[Wendelspanswick]

Hi, We have a 3300 with a mix of ISDN30 and SIP trunks, at the moment they are set up as an ARS Route List, 1st choice is the 10 SIP trunks then it overflows to the ISDN30 trunks (30 channels).
We have added some DDI's to the SIP trunks but of course most of the time the SIP trunks are busy with outgoing calls, is it possible to reserve say 2 of the 10 SIP trunks as incoming only?

Create a duplicate of your SIP Peer Profile and reduce the Maximum Simultaneous Calls. Assign the outbound routes to the SPP with lower max calls. Make sure your "SIP Peer Profile Assignment by Incoming DID" entries point to the "bigger" SIP trunk.

The only uncertainty I have about the above is if you're using registration. I never use registered SIP trunks, only IP-authenticated, so don't know what happens if you have two SPPs with the same registration info. Also, ancient firmware doesn't let you share SIP channel licenses between SPPs.

That worked, thank you.
