I am guessing that if you have your asterisk system divided into two computers, you need to use two different port numbers for IAX to work.
I think I read this in some posting that I can no longer find.
The default is port 4569, so I suppose the second one might be 4570 or 4568?
Can I ask a system admin to arrange for 27061 to use a different port and let me know where to change the port number in my set up?
Thanks
Ken
PS: how about a feature - default secondary port number that can be used without special intervention?
