Trunk Group with MGCP

[Ramon Antonio Veluz]

Hello Community,

We've added new PRI to our single PRI. PRIs are controlled by a 7.1.5 CUCM via MGCP, we are using 3925 15.0(1r)M16 for gateway.

Now, we are configuring SRST/mgcp fallback... I am wondering if i can assign the PRIs to a Trunk group; would it cause issues with MGCP or when it goes to SRST mode?

Thanks in advance!

In SRST, the mgcp application is not active. The fall back is to H323, so there is no impact on your trunk groups or mgcp

Thanks Ayodeji! I worry the trunk group command under Serial interface would have impact to mgcp application.

Ramon,

When running MGCP, Q.931 media is backhauled to CUCM so you should be ok. The trunk group will come into play when your dial-peers are used, this will only happen during SRST in h323 mode.

Thanks,
