Hi
I’m new to the forum, nice to meet you all…
First of all… sorry for my english 
I 'm having this strange problem…
I’ m using the latest trixbox, this is my configuration:
PSTN <----E1----> Cisco AS5400 <---- SIP (nonat) ----> Trixbox Box
I’m using idefisk for IAX2 and a Cisco IPPhone 7912 for SIP.
Everything works fine when I call from any phone (SIP, IAX2) to any phone or when I call from any phone (SIP, IAX2) to the PSTN.
Now, when I call from the PSTN to any extension, the phone rings, but when I answer I can’t hear anything…
The odd thing is that I configured a catch all inbound route to an IVR who has the same extensions configured as options 1 and 2… When I call the main E1 number (we call it “cabecera” but I don’t know how is called in english) the IVR answer, still can’t hear anything, but when I press “1” or “2” it transfer me to the extension and then I CAN hear the voice.
I have “yes” in “Allow Anonymous Inbound Calls” in “General Settings” on FreePBX.
Any help will be really appreciate.
Thanks in advance.
This is are my configuration files:
