asterisk users - Jan 2015 - Semi OT - LDAP multi-valued attributes support in SIP phones

Hello,

I've just started to look at LDAP in IP telephony.

1. I've read parts of RFC2798 which defines inetOrgPerson class.
I could find homePhone or telephoneNumber (multi-valued) attributes
but nothing like phoneExtension.
Did I miss something ?
I not, what would you advise to store private extensions in LDAP db ?

2. Several SIP phones can query LDAP databases.
Have you met any success with such SIP phones and LDAP entries with
two values for telephoneNumber ?
In other words, is it required by SIP phone to only have one
telephoneNumber or mobile attribute value per entry ?

Regards

it is some time ago that have looked at this kind of stuff... AFAIK most
phones have the possibility to define some sort of filters to select the
attribute(s). If I remember correctly the phones from Snom, Gigaset,
Tiptel and Yealink have a parameter to select attributes for name and
number.
