I unchecked all the stun servers and have it "Local SIP Port to listen on 5060" for all of them (pbx, and both of the express talk) now it give me a different error "error call attempt timed-out" and "the server is not replying"
even though i have them all listen on port 5060 as i mentioned above but the axon is listening port 5060 and the etalk on the same machine is on port 5061 (eg. 192.xxx.xxx.19:5060, and 192.xxx.xxx.19:5061) and the other etalk is on 192.xxx.xxx.21:5060), can you email all or you screen shots if you don mine. they might help
Thanks
