[Asterisk-Users] callerid, callwaiting callerid, Asterisk and ATA

[Dan]

Hi,

There is any difference in the way callerid is transmitted when a call is
received (in callwaiting mode- when in a conversation) or a regular call
(phone on-hook)?

I have a phone connected to ATA which receive and display the callerid
during callwaiting, but not when the phone is on hook.

Any hints?

Thanks,
Dan
