[Freeswitch-users] Strange problem with Freeswitch and external extension

[Michael Collins]

What kind of phone is it? Just curious. Also, be sure look at the SDP ports
and compare them to the actual ports to which RTP is being sent by pfsense.
It's entirely possible that there's a mismatch somewhere. If you can nail
down what is actually happening vs. what should be happening then it will be
easier to know where to look next. My money is on the phone or the pfsense
router.
