Sudden issues with IVR

OK - interestingly enough. If I setup up this way:

Incoming call -> Ring group B -> IVR,

it works when the ring timeout is set to 10 seconds. It doesn’t however work when ring time is set to 20 seconds.

When using both ring groups (at 10 seconds timeout each) it doesn’t work.

Is there some overall timeout that is causing this at 20 seconds?

going to try each ring group at 5 seconds.

Ok - with both ring groups set to 5 it works.

However, that is not enough time to pickup the phone.

I guess I now need to figure out what setting is causing this.

Check your RTP timeout in your Chan_SIP settings? Or could try session-timers=refuse.
