I am running Asterisk 1.4.21 behind a NAT
I have setup my asterisk server and my phones located intothe building are working fine.
I have a VoIP provider that I am using -> fine !
I can make phone called and receive without any problems.
Now, I have ONE phone located outside the building.
I can register
If I dial the extension -> the phone is ringing
This phone can make ring my local phone,
- I can’t hear anything
- The person over there can hear me
I thought about an NAT and RTP problems, but I really don’t know anymore what to do ?! ?
I place a another phone, registering to my asterisk server via Public IP address, thinking that I will force the COM to get out from the router and come back. Not sure about this is really happen like this or not
I forced it into the SIP file with
And this phone INSIDE the building works fine
the other one OUTSIDE the building doesn’t work ( And both have the some SIP configuration [ CANINVITE=no, NAT=yes…etc,)
I am lost …
Any Idea ?
Thanks and regards,
