Hi all,

the subject says it all. Technical details:
Asterisk 1.8.7.1
– 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?

Thx!!!!

BC

  • Do the call both ways again and check(post) the CLI output.

  • Hi.

    Thank you.

    You mean do each call separately? That works without a glitch, nothing peculiar.

    Thx,
