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

             Summary: Asterisk hangs up receiving unexpected frame format
                 Key: ASTERISK-28184
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28184
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 15.4.0
         Environment: CentOS Linux 7 (Core)
Linux *** 3.10.0-862.2.3.el7.x86_64 #1 SMP Wed May 9 18:05:47 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Asterisk versions: 15.4.0
            Reporter: Denis Lebedev
         Attachments: pjsip.conf

2 days in a row we have the following problem.
Asterisk receives {{g729}} frames from our partner while allowed formats are {{alaw,ulaw}}.
Logfile contains the following:
{noformat}
...
Channel PJSIP/partner-000164c6 asked to send alaw frame when native formats are (g729) (rd:g729->g729; wr:alaw->alaw;) (chan_pjsip.c:927)
...
HTTP session count exceeded 100 sessions. (http.c:1910)
{noformat}
Right after that asterisk stops to process incoming traffic, takes up all free memory.
Unfortunately we don't have any additional info (no core dumps or any other stuff) because we're forced to restart asterisk.

{{pjsip.conf}} attached.

What can we do with it?
