Problem: Before switching to asterisk, it was possible for people to seize the trunk and dial out any number, and thus bypassing the numbering plan. The error you currently get is:

-- Extension '' in context 'SJH05-A4400' from '282122348' does not exist. Rejecting call on channel 3/21, span 3

Solution: In zapata.conf, add overlapdial=yes to the group definition. This will cause an additional delay of three seconds before the number is forwarded:

-- Starting simple switch on 'Zap/206-1'
-- Accepting overlap call from '293312303' to '<unspecified>' on channel 7/20, span 7
-- Executing Dial("Zap/206-1", "Zap/g8/95212347||") in new stack
