Problem with cmd dial when reaching an answering machine


on my asterisk server, i call outbounds number with a dial cmd using a voip provider.

when i call someone, if it rings and he pick up the phone, everything works perfectly.

But when i reach an answering machine that pick up the phone without any ring tone, asterisk stay waiting that the phone rings and nothing happens.

Do you know what i can do to fix this issue ?

Thank you

You will need to take this up with the ITSP. You will probably need the signalling protocol traces for the outgoing call; assuming SIP, enable the full log in logger.conf, run core set verbose 5, core set debug 5, and sip set debug on.

Asterisk is waiting for the ITSP to tell it that the call is answered.
