When we do SIP <-> SIP with asterisk 1.2, we do NOT experience this. Polycom 501s, the instant you hit Send on the phone or the digit map times out, the target phone rings AND you hear ringback. it's instant, so I would guess this would be configuration on your end. back to the digit map timeout maybe?

I'm a little confused about your 'pick up and dial' phrase because, well, we're talking about SIP here and not Zap :)

I have had a lot of complaints about the time it takes to setup a call. I
have timed it and it is almost five seconds before it even starts ringing. The SIP device sends the request almost instantly but the channel is taking a long time to pickup and dial. It wouldn't be so bad but they hear nothing. I would like to provide ringback before the zaptel actually starts ringing
the channel. Has anybody done this, it seems like it would be a zaptel
option.

I'm not sure if it's related, but we are doing only SIP to SIP calling
with Asterisk 1.4 and experience the same thing. The signaling shows
up instantly, but it takes 5-7 seconds before ringback is heard.
Watching the CLI it does look like it takes a long time for the
channel to pick up an dial.
