I have a strange problem,
It's the same as described here: http://forums.asterisk.org/viewtopic.php?p=178420
But I haven't set up any custom stuff, All my extensions and queues are created in freepbx.
people can transfer between extensions if the call is internal, but if the call comes from a queue, then it gives that "not a valid extension" error as soon as you press anything after initiating the transfer - exactly as described in the link above.
here's my extensions file:
As I say, all the settings were done in freepbx.
I've got asterisknow 3 installed.
I did try yum update - and installed the updates, but that didn't help.
