ISCC config between SIP Server and Cisco TServer

Hello all

Other than external route points on each switch, and access codes for each, should there be a trunk configured on the SIP server switch pointing to the Cisco TServer IP with the relevant prefix? If so, should there also be a trunk on the Cisco TServer switch pointing to SIP Server:5060 likewise? Currently the only Trunk DN configured is one on the SIP switch that actually points externally to the CUBE which would then in turn route back via CUCM to the Cisco TServer (which doesn’t appear to be working as is).
