434
In Switch A above, the IP Trunk server’s originating entries will be as follows, in
order for calls through that IP Trunk server to be routed to Switch B and Switch C
appropriately.
These entries allow any line/port on the IP Trunk server to carry calls to the other two
locations. It also allows each unique string (extension range) destined for one of the
other two locations to be evaluated and routed to the appropriate location. There
would need to be terminating entries in Switches B and C that correspond to the
entries above, allowing the appropriate dialed strings to be terminated at those
locations.
For example, in order for calls to be received at Switch A, from Switch B and C, the
terminating entry in the IP Trunk would be as follows:
Only one digit is required to uniquely identify calls to this location, no other location
has extensions that begin with “6,” and since this encompasses the entire range of
extension numbers, only this entry is required.
