Hi,<br>
<br>
I am experiencing a hard to solve problem with my VoIP provider. I can
make calls without any problem but I can not receive any. Actually,
calls arive to * but the phone just does not&nbsp; ring. I believe must
be a problem with NAT but&nbsp; I think I have a good config:<br>
- Extensions have nat=always and qualify=yes<br>
- Have introduced in sip.conf&nbsp; Externip and localnet<br>
- ADSL modem/router is redirected to my * server<br>
- With sip debug I can see the call arrives<br>
Am I misssing something that someone else can see?<br>
<br>
Appreciate any hint. Thanks<br>
