Incoming Fax Erros

[Chidado]

I am seeing more of this in the logs:
Timer T2 expired while waiting for next fax page

Clues on where to pounce? Much appreciated.

I have setup fax server on this inbound route. Goes directly to the fax server extension. No channel limit. Is it possible that another incoming call can disrupt the incoming faxes?

For troubleshooting purposes, where do we turn on ECM for fax server?
