i have an asterisk install with a digium 4 port fxo card and cisco 7960
sip phones -- running on a compaq Pentium III (Coppermine) at 800Mhz
256KB cache and 1GB of ram.
when a call comes in on zap/1-1 for example, the delay between when zap
sees the line going to ring state, and when the desktop telephone rings
can be as long as 7000 milliseconds (or about 3 or 4 rings on an ear
piece).
below is some of the log -- note 2 seconds to get from Ring Begin to In
Use and a total of 7 seconds before the sip phone rings.
anyway to speed this process up?
cheers
charles

It would appear the progress is associated with waiting for callerid
info. If you are in the US, callerid occurs between the first and second
ring. That's about 7 seconds or so.
If your pstn line does not have callerid, then add statements into your
zapata.conf file like 'usecallerid=no', 'immediate=yes', etc. I don't
recall exactly which statements are needed, but start with the above two
and see what you get for delays.
