[Asterisk-Users] Something very strange regarding callerid

[Dan]

Hi,

I have disovered something very strange regarding callerid on my phones.

Callerid works on Calll Waiting!!! ...when connected to ATA186 and Asterisk,
but not when not in a call and the phone is on hook. It display just the
name, but not the number...?!?!
As my PSTN line does not transmit the name, then it display nothing...

There is any explanation for this behaviour?

Thanks,
Dan
