[General] VoIP For Home Usage

[Ahmad Al-Ibrahim]

Bo Rashed,

I've tried that without luck, I'm trying to connect to asterisk from my
mobile using 3G/GPRS which is behind NAT, and asterisk is behind NAT too.

trixbox1*CLI> sip show peers
Name/username              Host            Dyn Nat ACL Port     Status
300                        (Unspecified)    D   N   A  5060     UNKNOWN
200/200                    192.168.1.8      D   N   A  5060     OK (74 ms)
100/100                    95.66.116.121    D   N   A  5060     OK (946 ms)

The device is registered with asterisk without problems, calling will
ring both ways, the problem is with the sound, RTP not being connected
properly.

Ahmad Al-Ibrahim
