[Asterisk-Users] Preserving CallerID when forwarding to cellphone

[Robert Goodyear]

Submission to the list:

I noticed that some VoIP call origination prepends a + symbol ( plus 
sign ) on the callerID presentation.

When I forward a call outward, this breaks the callerID, so I'm using 
this to clean up the string as soon as the call comes in:

exten => s,3,SetCallerID(${CALLERIDNUM:1})
