Do you have outbound proxy configuration on your setup? I have a same issue with this 32 sec call dropped. I manage to fix it by doing the outbound configuation. Btw, my setup is I have sip server behind NAT.
Leg A <-> Local SIP server <->NAT <-> Cloud SIP Server <-> Leg B
My local calls works fine. I configure the internal and external profile the ip of my local sip server 192.168.x.x
Thanks,

I've connected a few different clients, 3 soft phones and 2 ATAs. When making calls with some of the clients the calls are dropped after 32 seconds. For other clients the calls will proceed for half an hour no issues. I have absolutely no complexity here, it's all internal phones on the local /24 lan. There are no firewalls, traffic only goes via a switch. I have no external SIP gateway, none of the clients are behind a NAT. I've done extensive googling and everything I find talks about NAT issues and VPNs, multiple subnets etc. I'm not running any of that. Packet capture and more details below.
