[Asterisk-Users] X100P delayed ring on incoming calls?

[Joseph Gutowski]

3-4 rings seems kind of long, I usually see 1.5-2 (enough to grab the
caller ID here in the States).

The only way I know of to speed it up is to turn off all of the
features like distinctive ring detection, caller ID, etc. -- depending
on your usage, that may help some. I haven't confirmed that this
actually does anything myself, but it seems logical that Asterisk
could pick up quicker if it wasn't waiting for caller ID. This is what
people suggest if you Google the list.

Either way, the best I've ever managed on the X100P's was 1 ring
before Asterisk picks up and starts doing its thing.
