In my dial plan I’m forwarding a call that comes in to an external number.
Caller call’s DID -> Hist Asterisk Server -> Asterisk Server sends call back out trunk to ext number -> call connects with ext number
this works fine, at the destination end they have an IVR that echo’s DTMF tones pressed in order to help me diagnose the issue I’m having.
If I press any digit 0-9 or the pound key the endpoint immediately reports the digit pressed. If I press the * key it delays 5-6 seconds before it registers on the endpoint. If I call the ext termination number from my land line (provided by telco) all the keys including * report immediately so it seems asterisk is waiting to process something when it see’s * pressed. How can I prevent this and have it pass on the dtmf immediately like the other numbers.
