[Freeswitch-users] Calls dropping on SIP timer expiry due to UPDATE's being ignored.

Hi,
Hope someone knows how I am able to get around this one. Here goes...
Did an upgrade to trunk (from a July vintage build) last week and
noticed calls out to a provider were now failing after about 30 seconds
or so - post answer. Tried latest (15183) - same thing.
Analysing, I see that I have multiple UPDATE messages now being sent to
the provider, but no response being sent back to FS. So FS times out and
eventually kills the call.
Interestingly, it only drops the A-leg; the B-leg remains up till the B
party hangs up.
I cant recall seeing these UPDATE messages before...
The intent of the UPDATE seems to be to send the callee name & number to
the B-leg.
If its the provider's sip stack that's broken w.r.t. handling UPDATE -
is there any way to get around it by doing something in my config to
ensure these UPDATE's are not 'triggered' ?
Some traces below.
Any suggestions welcomed...
Best Regards
Keith
Pretoria, South Africa.
