X100P and Asterisk 1.2.7.1 here;
simple config to ring SIP extension (ATA-186) on incoming call from the POTS line.

I experienced about a 1-ring lag between the SIP phone and the rining on the POTS line.

I fixed this by setting:
usecallerid=no
in zapata.conf

(I do not have callerID service on my POTS line anyway). I assume that Asterisk
is waiting to see the caller ID data between ring 1 and ring 2 in order to be
able to switch based on caller ID data (which never comes). Disabling it allows
it to not have to wait.

Not sure where this additional lag is coming from. Could be something inherent in
your SIP phone I guess (my only SIP experience is with Cisco ATA 186).
