I’ve been reading everything I can find about asterisk for the past week, and I’ve got a couple of things I’m not clear on.
On my home network (behind a dlink router - nat) everything works fine. Got a couple softphones and a dta310 (with flash update) working just fine.
When I try to connect from outside my home network (using x-lite) I can connect, but when I call another extension or one of the * features (*61 for example) I get dead air. From everything I read, connecting from a network behind a nat router to an asterisk server behind a different nat router is difficult at best (using SIP.)
So I take that what I’m experiencing is normal? (I’ve got my asterisk server in the DMZ with the following ports forwarded to it, 4569, 2727, 5060, 5036, 100000 to 200000 (all UDP, with 5060 TCP forwarded also.)
So that takes me to IAX and IAX2, I take it that these are not compatible, meaning that if I configure a IAX2 extension using AMP that I need a IAX2 softphone?
Could someone recommend a decent windows IAX2 softphone?
And lastly, in the configuration for extensions, what is the significance of context. Everything I have set up (test extensions) are all ‘from-internal’. Does that mean that Asterisk is expecting it to be from the internal network (home network) or is it more like group/policy type thing?
Sorry for the rambling, but I think answers to the above would really help move me along.
Thanks in advance.
