Hi.
I’m currently thinking about global telephone directory for our company. The main point is constantly up-to-date and completed list of our corporate phones within any single SIP-phone.
So, is there any Asterisk-compatible technology/protocol/module which can be used to create that directory? I’m still searching, but it looks like Google hasn’t information about it 
Or I use wrong search phrases, quite possible.
I know that hardware SIP-phones have a directory which can be configured remotely. But they are different and moreover, we also use soft-phones (3CXPhone) that have not this functionality.
Any ideas?
