[cisco-voip] Remove Caller ID Delay

FXO ports usually take at least one ring for it to PLAR over to the gateway. If you haven't requested Caller ID from telco and you have it PLAR'd, you'll encounter even more rings before the call enters the gateway ringing an IP phone on the gateway side. This is normal.

CCM 4.1.3, H323 2801, FXO ports.

People call in, they will hear 1.5 rings before we hear any rings.  I assume this is setting up Caller ID.  Anyway to stop this, just let the phone ring before Caller ID is transmitted?
