------------------------------------------

             Summary: directmedia=no does not work in Asterisk 13.1.0
                 Key: ASTERISK-24657
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24657
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 13.1.0
         Environment: The Asterisk server runs under Fedora 20, with static ipv4 addresses and working ipv6.
The yealinkphone is a sip client of the asterisk server.  The yealink phone has a non-routable ipv4 address and a routable ipv6 address, but preferentially uses the ipv6 address.
The service provider, callwithus, does not have an ipv6 address.
            Reporter: Thomas B. Clark


I just upgraded from Asterisk 11.14.2 to asterisk 13.1.0, and that caused directmedia=no to stop working.  It worked in 11.14, and using the same sip.conf it does not work in 13.1.0.  Here is the relevant part of sip.conf:
[yealinkphone]
type=friend
host=dynamic
context=outgoing
secret=xxxxxx
defaultuser=xxxxxxx
insecure=port,invite
directmedia=no
qualify=yes

And here is what happens:
    -- SIP/callwithus-00000003 is making progress passing it to SIP/yealinkphone-00000002
       > 0x7fa784016470 -- Probation passed - setting RTP source address to 69.85.185.222:21708
    -- SIP/callwithus-00000003 answered SIP/yealinkphone-00000002
-- Channel SIP/yealinkphone-00000002 joined 'simple_bridge' basic-bridge <5fb81915-9eaa-4b69-9be8-26f8a1db1fff>
    -- Channel SIP/callwithus-00000003 joined 'simple_bridge' basic-bridge <5fb81915-9eaa-4b69-9be8-26f8a1db1fff>
       > Bridge 5fb81915-9eaa-4b69-9be8-26f8a1db1fff: switching from simple_bridge technology to native_rtp
       > 0x7fa70400afd0 -- Probation passed - setting RTP source address to [2601:8:9181:4800:215:65ff:fe27:ac8e]:11786

Even if I had directmedia=yes, Asterisk shouldn't issue a reinvite because the yealinkphone is using ipv6 and the service provider, callwithus, is using ipv4. However, as I stated, I have directmedia=no, so nothing else should matter, but the statement is being ignored.

I have worked around the issue by setting ,,t at the end of all of the Dial statements, and that successfully prevents switching to native_rtp.  Nothing else I tried does.
