I’m having this strange issue with skype connect. The trunk registers OK, I can see 200 OK for REGISTER and OPTION.
However, when I initiated a call the INVITE packets get no answer from skype (Trying, Ringing, OK, nothing). This results in 6 INVITEs sent and at the end the call getting dropped by asterisk. What’s worse, is that the destination actually rings, but it’s a dead call apparently.
I’ve tried everything in the FROM SIP header, tryied NAT and not, even tested with DMZing the asterisk VM with a public IP. Tried various softphones straight to skype. Tried destinations in various countries and tested from different sites with different ISPs everything produces the same behaviour from skype.
