Hi people,
I have a big problem here and I don't know where I start to solve this issue.
Topology:
Company A has 2 building and 1 VCS that works for both building.
Company B has 1 building, 1 VCS, 1 TP Server and 1 MCU Codian
Both VCS are connected through a SIP Trunk
The problem:
The communication works correctly point to point from the two building from "Company A" to "Company B", everything works correctly.
When we perform a call to the TP Server / MCU from building A (company A) to Company B everything works well. No problems here.
However, when we performed a call to the TP Server / MCU from the building B (company A) to company B, the DTMF is not sent, if we create a room with PIN for example, it is not possible to connect the TP Server / MCU, because the company B does not receive the digits.
POINT TO POINT
Building A --> Company B = OK
Building B --> Company B = OK
Muilt Point
Building A --> Company B = OK
Building B --> Company B = The DTMF wasn't send
The building A have the same equipment, but TC 5.x and in the building B is TC 6.x
Can any one help me?

To see whether it's a TC software issue - have you tried a TC5/6 endpoint in the other location from where it works? Ie, try a TC6 in Building A and/or a TC5 in Building B.
In any case, I'd recommend you upgrading the TC5 (and TC6 if they're less than TC6.1) due to the multiple vulnerabilities in the software: Cisco-SA-20130619-TPC.
And even more so, to version TC5.1.11, TC6.2.1 or TC7.1.1 to address the OpenSSL Heartbleed issue.
