Speed up dialing from SIP to ZAP

hi all

i purchased a Dock n Talk and attahced to a TDM 400P with 2 FXO and 2 FXS to enable GSM calls.

Everything is fine with the exception it takes a while for asterisk to acknowledge the number, pick up a line in g0 and dial.

ie

– Executing Macro(“SIP/0-0832d170”, “GSM|01242227929|30”) in new stack
– Executing Dial(“SIP/0-0832d170”, “Zap/g0/01242227929|30”) in new stack
– Called g0/01242227929
– Zap/1-1 answered SIP/0-0832d170.

Is there a way to have asterisk dial immediately once the number is sent instead of waiting for x seconds from ’ Called …’ to ‘Zap …’

Also, CDR seems to captured the calls as ‘ANSWERED’ even when the other end did not pick up the line or busy.

thanks for your help
