TSS Configuration

Add in a PBX cluster

In this case we made the server domain the address of CUCM this is because Cisco wants URIs to be number@cisco so for example 778318@10.221.9.133

Add Lines

In the TPO Cluster, Add in the TPO Lines

Extension = Your extension ( 778318 in our example)

Register = Yes
PBX Cluster = “PBX Cluster for SBC”

Add TPO place

Place Type = RingdownDynamic

Other Configuration

If using Cisco Call Manger as the SIP Trunk the we need the To header to be in the form number@Cisco so in our example if we were to call 5550029 we would want 550029@10.221.3.188

To make this correct you need to set the SIP local domain in the Turret BOOT setting to be the address of CUCM. This may also be required for some carriers. It is also possible to do this with a manipulation in SBC if you need one cluster to control numbers to two domains.
