the subject says it all. Technical details:
– Asterisk 22.214.171.124
– Behind NAT
– Using external SIP Provider
The call forwarding is tested both with this functionality on the phone and with configuration in the dialplan. In the latter case a database variable is set to the external number, if set a Dial command calls this number. So really nothing fancy (actually I followed the example on http://www.voip-info.org/wiki/view/Asterisk+call+forwarding ).
sip.conf has nat=yes, externip= … and I tried every setting of directmedia in the providers configuration part.
Followme works flawlessly, so I’m really wondering if this is a NAT issue.
Can anyone point me into a certain direction?
