[asterisk-users] One way audio when dialing multiple registrations

[Jonas Kellens]

One-way audio is mostly firewall problem.

Are you behind firewall ?

You can check the audio-ports that are being used in the SDP-message by 
doing a /sip debug/.

Maybe you do not have enough UDP-ports open for the audio ?
