Asterisk with voip gsm voiceblue

I want to set up a pbx with a voip gsm VoiceBlue.
I have a bridge I VoiceBlue configured with pbx, but when I made ??a call pbx to the gateway I hear a dial tone but the phone I want to join does not ring.
I do not understand can you help me

This is an Asterisk forum not a Trixbox forum. So there is not a lot of chance that someone here can help you. Furthermore, Trixbox is a dead product for quite some time. If you want to use a bundled distribution, I would suggest Elastix, PBX in a Flash or any other active distributions.

ok I’ll change the title of my post.
thank you
