Echo-Cancleation on PRI with MGCP PRI Backhauling

[tringwelski_2]

Hi,

I have a PRI with MGCP enabled (Pribackhauling) 12.2.11T, 3640, and I have to keep putting the "echo-cancel coverage 16" under the voice port, when I reload the router, the mgcp removes this configuration, I cannot locate this in Call Manager to enable it, does anyone know a workaround?

You have to do a shut, no shut on the voice port. If you don't it will not save the config.

This is a bug in the code if your using the config paramater and auto d/l the commands, the echo coverage is removed each time, so do not use the auto config /parcing of the cli , manually enter the info and remove the server config command.
