I'm running a CME 8.6 setup on a 2811 router.
When calling from a 9971 SIP phone (remote to the CME) to another 9971 SIP phone (remote to the CME but in the same subnet) the call gets dropped out at 18 seconds.
However, the call succeeds if I enable the following command under "voice service voip":
bind all source-interface vlan 1
Is there a way to not have the interface bounded and still have these WAN SIP calls work?
