[Freeswitch-users] Audio Connection Delay with SCA

Thanks for the reply.
We use all CSICO SPA504G phones.
I did have the jitter buffer set up "HIGH" (choices: Low, Med, High, Very
High, Extremely High). I dropped them down to Low now for testing. They do
have pretty good network speeds (business level cable modem).
There is also something labeled: " Jitter Buffer Adjustment: " Choices
(Up, Down, Both, Disabled). I have both.
However, the issue is present, but far less pronounced in non-shared lines.
They have always said there was a connection delay at this site, but with
SCA it seems to be compounded.
Maybe Group Call Pick will work better for them, they are all in the area.

what type of phone? If it has a jitter buffer, you can try reducing or
its probably a combo of jitter buffers charging up on the phone, and the
auto-ajust trying to fix the broken sdp for NAT.
