I need to add a CUBE to terminate the SIP PSTN trunks in an existing environment. They have CVP 4.1 but will be upgraded to 7.x before the CUBE deployement. I will use a 3945 with IOS 15.001. They have a gatekeeper for call routing.
I want to know if anybody has any experience of the below call flow and if I may come up with any problems ?
PSTN ----> SIP -----> CUBE ----> Gatekeeper -------> CVP
I will probably need to use MTP ( Software on CUBE ). But as the connection from callmanager will not be directly to the CUBE, I think I should check the MTP Required box in the existing Gatekeeper controlled Trunk. Would this cause any issues ?
