Hi again everybody,
I have T41p phones (firmware 188.8.131.52) on a FreePBX (v12) system connecting to SIP provider. My issue is that when the incoming call comes in, there is a brief delay in audio. Eg. when the person answers and says “Hello thanks for calling”, you basically don’t hear the “Hello Thanks” part of that, so maybe about 1 second audio delay. This could be the establishment of the SIP call or possibly related to the phone timers. Is there anything in the phone configuration that could be adjusted to prevent this delay from happening?
I believe however, this is SIP related. It takes a bit of time when pickup up the call for it to get established and RTP to start flowing. I don’t have this issue when I use say an IVR to answer the call, because it has already been established. Anything you can think of if say I setup an incoming ring group delay?
