[asterisk-users] Asterisk and NAT one way audio

[Silvia Menendez]

Hello may situation is the next:

Asterisk <--> NAT1 (router)<---> internet <--> NAT2 (router) <--> x-lite
                          ^
                           |
                          ip phone (cisco)

Asterisk and de cisco phone are in the same LAN. I want to make a
call between the x-lite and the ip phone. I can do the call but there is
only audio from de ip-phone to the x-lite. From the x-lite to de ip phone
there is no audio.
I have made port fordwarding in the router 1. I have opened ports 5060-5070
to SIP and 10000-20000 to RTP.
In the sip.conf file I have externip, localnet, bindport, bindaddres, nat =
yes etc.
I have used wireshark to see the frames and there is rtp traffic in both
direccion so i don´t know what the problem is.
I have used the x-lite in the same LAN than the ip-phone and all is good so
the two phones works fine.
What is the problem? Thank you in advance
