[Asterisk-Users] extension pattern matching

[Graham Turner]

dear all, was hoping someone could give me instruction on the syntax of
extension pattern matching for letters

the proposed 'dial plan' is one where any letter in the dialled digits
causes the pbx to assume we are dilaling a sip url and as such forward to
the appropraite sip service provider

was hoping to avoid the plan in john todd's example that assumes anything
prefixed with 3 is a sip address
