If you believe that proxying of fax calls through rtpproxy is the cause,
maybe you could identity the upgrade of rtpproxy you did that caused the
problem? That would help to identify the change in rtpproxy that could
have caused it.

Hello
We use SER and rtpproxy for a couple of years over public network. It
worked perfectly before. The users from different LNA can talk to
each other over SIP call (xlite or Linksys adapters). We could fax
over SIP from other countries. However, fax stopped working shortly
(about 6-month). But SIP call worked fine till the beginning of this
year. Suddenly, sip-phone only hears ring. There is no sound on both
sides.
Do anyone have the similar problem or encounter stability issues in
this setup (SER + Rtpproxy)?
Best
Steven
