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
