Martin Dindos updated ASTERISK-27604:
-------------------------------------

    Description: 
I've set up a test install of Asterisk 15 on my 64 bit x86 machine. All phones were on local network (no NAT). All extensions were registered using the old chan_sip. With media encryption disabled on all extensions everything worked as expected.
After turning on media encryption (srtp) the calls resulted in one way-audio. The audio worked in the direction 
(phone 1 - using srtp -> phone 2 srtp disabled) the reverse direction was not working.

I've downloaded and compiled Asterisk 13 on the same machine with the same configuration. Everything started to work no audio issues regardless of whether srtp was enabled or not.
