Ok, I suspect some else is binding to port 5060 on the system in this case. As per:
0x7f000001 : Port=34760
86293360 sip_stack Error ERROR - SOCKET - RvSocketBind(sock=15,addr=192.168.0.86:5060,scopeId=0,range=(nil),useRange=0,errno=98)=-2145371137
86293360 sip_stack Error ERROR - TRANSPORT - TransportUDPOpen (Local Address 0x0xb5d3ab68): can't bind UDP socket -1 (crv=-2145371137,rv=-1:UNKNOWN)
This is O/S socket call failure. Check for netstat output to see what else might be using that port on the system.
