Hi to all,
I’m a new bie of FreePBX and Asterisk, and I’m trying to setup my first VOIP system.
I have FreePBX 2.7.0.5 with a PCI card TDM400P and 2 FXO channel connected to 2 analog phone lines. I configured the system with 3 GrandStream phone and 1 XLite softphone.
All works perfectly if I made internal call or receive call from the TDM interface, but I can make no external call from the SIP phone.
I configured an outbound route over the trunk Zap/g0 created by default from FreePBX but when I try to make an external call, I get always the voice saying the channel are all busy.
Where is the problem in your opinion?
Thank you very much for your help!!
