Hello !
We've got Cisco AS5350 as E1-to-VoIP gateway. On our calls from VoIP into E1 call flow looks like this:
VoIP phone <---> Cisco
------> SETUP
<------ PROGRESS (this is fake progress)
..... TCS-MSD interconnection. ....
<------ PROGRESS (here is real one)
<------ ALERTING (real alerting and my phone starts ringing only here)
..... and the call continues ....
Question is: how could we disable that first fake H.323 PROGRESS message?
Thank you.
