crush when Contact contain ";isfocus"

[sergey-safarov]

We use FreeSwitch as a conference server.
When FreeSwitch send "isfocus" in Contact header, then Linphone dies.

Example

Contact: <sip:3500@192.168.100.31:5060;transport=udp>;isfocus

isfocus usage defined rfc4579

If you have FreeSwitch server, then you can reproduce the issue using this dialplan

<include>
  <context name="default">
    <extension name="conference">
      <condition field="destination_number" expression="^3500$">
        <action application="answer" data="is_conference"/>
        <action application="conference" data="3500@video-mcu-stereo"/>
      </condition>
    </extension>
  </context>
</include>

Please attach SDK logs from the start of the app to the moment it crashes and the symbolized stacktrace of the crash (using gdb or another tool).
Also, what version of the SDK are you using?

[sergey-safarov]

Sorry, I do not use SDK
I use latest appimage build.
Think I cannot get a stack trace for appimage build.
Should I collect linphone logs?

@julonexus Can you handle it please?

[sergey-safarov]

I can prepare SIPp script as a test case.

Hi,
What is your version of appimage? Is it from releases or snapshots? Logs will be helpful thanks

I cannot reproduce the issue now.
I will reopen the ticket when I catch the issue again.
