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
