[Freeswitch-users] Translate 415 response to 488 across bridge

[Spencer Thomason]

I will create a jira.  Unfortunately I’ve only seen this on our production boxes and the UACs (Allworx) in question are operated by customers.  I can collect signaling traces and try to reproduce this.

Thanks,
Spencer

That depends on how it actually handles it.
You would need to get a full debug traces of both situations and maybe put it in a jira

sofia global siptrace on
sofia tracelevel alert
sofia loglevel all 9
console loglevel debug

Hi Anthony,
Thanks for the response.  So maybe a profile flag that if set, maps a 415 to 488 in sofia_handle_sip_r_invite()?  But is a profile flag actually needed?  It seems if a UA responds to a ReINVITE with a 415 Unsupported Media Type response, the permissive way to handle it would be to treat it the same as a 488.

Thanks for your input.

Regards,
Spencer

You can either make a specific hack for this problem and wrap it in a param.  Make some kind of feature to translate supplied code X with code Y or use a SIP proxy in front so you don't have to hack on FS.

Hello,
We have a few UAs which reject a T38 ReINVITE with a 415 instead of a 488, ugh.

If the UA sends a 415, freeswitch send a BYE with a Reason: Q.850;cause=79;text=“SERVICE_NOT_IMPLEMENTED” but if the UA sends a 488, the 488 is passed across the bridge and the T38 ReINVITE is successfully rejected and the call continues normally.  Is there a way I can get Freeswitch to treat the 415 as a 488 and send a 488 across the bridge?  If its not currently implemented, can anyone provide some hints and I’ll create a PR.

Thanks!
Spencer
