78xx XML Directory search on incoming phone call

[Dr Alban]

The 78xx series of phones query the XML directory for an incoming phone call.

What is the format of the response the phones are expecting?

Hi,

78xx phone uses UDS to query directory. UDS devnet guide should include
format details of request and response

Thanks but this is for a 3PCC phone so there is no CUCM involved.

It's what is referenced here:

I've found out through experimentation that the phone simply expects the normal XML directory. It will then find the entry that corresponds with the incoming or outgoing phone number and display it accordingly.
