SIP client behind NAT is not working. Asterisk is not behind NAT, but accessible only by dyndns.

sip.conf:

sipdebug=no

externhost=dyndns

Any idea from someone who has 1.8 properly running?

I have the exact same problem. It’s NO-IP un my case, but this has nothing else different.

In my case, I can make a call without any problem. But, as soon as I’m receiving a call, I’m getting

on the server logs. And the message gets dropped in the voicemail immediately.

Anyone?
