Hello all

I put a Telular gsm plant to a fxo port, I try calling to a cellular central number for test that works, but at the time that call answer for the plant, immediately is hangup.

For test the working in the Telular plant, I connect a normal phone, the call is answer and working fine, but at the time that the plant answer the call I hear a “click”, I think that this is the reason for that the call is hangup in Asterisk.

Someone knows how prevent that Asterisk detect the “click” like hangup signal.

Thanks

Sorry bad English.
