Well that narrow downs the possible solutions to doing some stuff on FS only ! - I really think that Stopping or applying a work-around for the re-invite from Broadsoft will get this fixed. I did some googling on the SIP 491 code and re-invites in FS and mostly they point to session timers or some media_bridging option in dialplan.

The Sonus and M6 are out of my control they belong to my upstream and downstream so I have no access to them

Broadsoft support will not work this issue because FS ACKs the 200 OK so dialog is completed at least on the B-Leg so that's when the M6 sends the 2nd invite however the dialog has not completed on the A-Leg but FS still passes the Invite along resulting in the 491

OK, and can you see whats happening inside the SONUS when it gets the second invite (debug logs etc)? Can you control the M6 to stop re-invites !?

Hi,

Can you please manage a proper sip trace for this ! I'd really love to troubleshoot and analyse the sip traces.

What is the equipment on your A-leg ?

I would like to add an update to this and maybe someone has some other suggestions - It does look like that FS is disconnecting the call with cause code 31  [NORMAL_UNSPECIFIED] I did not notice the time stamp difference on the Bye when I first looked at the log's

The basis of the issue still stands a 491 Results in the B-Leg being disconnected

We are seeing some instances when we send a invite from the B-Leg back to FS and FS passes the invite to the A-Leg that the dialog on the A-Leg has not fully completed yet causing a return of a 491 from the A-Leg side causing the call to be disconnected. wanted to see if anyone else has seen something like this while running FS and if anyone had any suggestions on a fix?
