I'm trying to call from DruCall to Asterisk and I get this error:

WARNING[11021]: chan_sip.c:8687 process_sdp: Error in codec string 'F
103 104 111 0 8 107 106 105 13 126'
  == Problem setting up ssl connection:
error:00000000:lib(0):func(0):reason(0)


I'm guessing my Asterisk is too old (it is 1.8 from Debian).  Can you
confirm which version is needed to parse a media descriptor with SAVPF?
 Do I need to upgrade all the way to v11 with WebRTC support, or was
avpf support added in some intermediate version?


Also, I'm using a SIP proxy and it takes care of handling all the WebRTC
connections and proxying the requests into a normal TCP/TLS connection
to Asterisk.  I was hoping to avoid opening up WebRTC access directly on
Asterisk.  One effect this has is that I can't control the `avpf=yes'
setting on a per-peer basis, as the proxy is carrying requests from
various types of peer, some public, some private.  Is there any outright
reason Asterisk can't support (S)AVPF on demand?
