Hi,

I’m trying to setup a sip trunk. The asterisk version is Asterisk certified/11.6-cert12. I had to change the CallerID to a pilot number of the trunk as provider only accept it. but when i dial I’m getting below error. Cannot hear anything

Any suggestions to fix this issue? Please help

Best Regards, Madushan

  • and this is working without any issue in elastix. I need to setup this in pure asterisk installation.
