Hello Kamailio,
Is it possible to use RTPengine with a single UDP port for all calls instead of a range of ports?
For example, when an invite is received or sent, the offered SDP for RTPengine is to receive RTP packets on a single port that is the same for all other calls, so that on firewalls only one port is to be opened.

It is not. RTP is not multiplexed that way.
The protocol you're looking for is IAX2. ;)

Thanks for the guidance, Alex, I will look into IAX2 ________________________________ From: Alex Balashov via sr-users sr-users@lists.kamailio.org Sent: Tuesday, September 26, 2023 8:44:00 PM To: Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org Cc: Alex Balashov abalashov@evaristesys.com Subject: [SR-Users] Re: RTPengine use single port for all calls
