Stacy Vinson updated ASTERISK-25924:
------------------------------------
Description:
I'm having a problem getting my Polycom VVX 600 working with SRTP and PJSIP I get a 488 after the RTP/SAVP.
The Polycom works fine with SRTP if i use chan_sip, and my AASTRA 57i works fine with PJSIP and SRTP.
The Polycom also works fine with PJSIP if i disable SRTP.
I also tested a few soft phones with SRTP enabled on PJSIP and did not have any problems. so it looks like it's only a
problem with the polycom phones.
