Hi guys,
I have a friend that's trying to call me but he
gets message
"488 Not Acceptable Here"
When I call him everything is ok. He is behind nat
and uses Draytek Vigor 2600 ADSL router.
Stun tells:
Port restricted NAT detected - VoIP will work with STUN
Does not
preserve port number
Does not supports hairpin of media
Public IP
address: his_ip
Any idea what is the problem?
Thanks in advance,
Pavel Siderov
