We have a new install that has multiple divisions thus requiring the same extension to use different outbound CID. We resolved this by prepending the outbound routes with *81, *82, *83, etc with the 10 digit number (ie *81NXXNXXXXXX). 10 digit dialing without a prepend *8x goes to the DeadRestricted trunk.
This all works great until we tried to build the Asterisk PhoneBook and add entries for external calls as the field for the Number to be dialed will not accept the *81 as a prefix.
Does anyone have another suggestion how to accomplish this?
