[Asterisk-Users] One-way audio

Have you looked at the various comments regarding NAT on the wiki? I think 
you need to set the following in sip.conf
nat=yes
localnet=192.168.0.0/255.255.255.0 (or whatever)
externip=WAN IP address
canreinvite=no

  Hi all,

Maybe someone encountered similar issue.

I have an * with the incoming DID over SIP. * is behind a firewall. I
have no issues with other SIP devices connected from the outside
network, however on that DID when I receive a call I can hear only
incoming audio, no outgoing. If I setup a "playback" with some audio
stream, * just disconnects the call right after it receives it. The same
issue happens no matter which client is being connected to that DID. For
example:

[inbound]

exten => xxxx225612,1,SetAccount(xxxx225612)
exten => xxxx225612,2,Ringing()
exten => xxxx225612,3,Dial(SIP/bt101,50)
exten => xxxx225612,4,Hangup

If I change Dial(SIP/bt101,50) to Dial(IAX2/firefly,50) it does not
change anything.

This example can only receive audio.

This one just answers and disconnects call the same second:

[inbound]

exten => xxxx225612,1,SetAccount(xxxx225612)
exten => xxxx225612,2,Answer
exten => xxxx225612,3,Playback(vm-goodbye)
exten => xxxx225612,4,Hangup

Sincerely,

--Andy
