Gill, Thank you - you pointed me in the right direction. I solved this by selecting "Force Timer" to Yes. The Description says this tells it to "Use timer even when remote party does not support". I don't know why the difference, but at least it's working now.

Its on the page where you setup the extension. Hope that works Gill On Fri, Apr 20, 2012 at 4:53 PM, Rob Morin <rmorin@blie-ent.com> wrote: I recently (4/17/2012) did a "make current" on my Freeswitch PBX. (Last time I had done it was probably in January.) No particular reason for the update - just timely. After the update, we're now seeing calls drop consistently at the ~1:47 mark. Obviously, this wasn't the case beforehand. I can provide a pcap file and Freeswitch log of a call demonstrating the issue; I'm just not sure what the best method to do so is. The FS server is sending a BYE, the REASON is 'SIP; cause=408; text="Session timeout"'. On my end, I have a Grandstream 502 and I can see the keep-alives are working. But now it is getting disconnected while it wasn't before the update. Any ideas?
