[Asterisk-Users] Passing Callerid

[William Piper]

How do I setup a dial plan that will allow a customer to set their own
callerid?

No matter what I try, the username that I have for them in sip.conf is
passed because I have no callerid setup for them. If I setup a callerid in
sip.conf that is passed & I can change it and it works. 

That is well and fine but I want to send what the customer is passing as
their callerid... what am I doing wrong?

To eliminate the customer being wrong, I tried with a pair of my asterisk
boxes and I have the same problem. I even try setcallerid(1234567890) and it
still doesn't pass.

Could it be because I am having them register?

Thanks,

bp
