[Asterisk-Users] Caller Name: Asterisk reading too fast

[Alexander Lopez]

This is because Caller ID name is being send in the FACILITY messages
instead of in the SETUP.

Wait(1) is the solution, There is nothing wrong with your install or
asterisk. 

Asterisk picks up on SETUP as it should. When it recieves the Name via
FACILITY it propigates it in the channel, however the other channel has
already started to ring so it does not have the name when it gets built
and since ZAP, IAX, and SIP, etc. do not support Caller ID after the
setup you never get it....

Search on the Mantis for this....
