Summary:                    SIP display-name needed to be empty for Avaya IP500
Description: 
Hi,

a customer of ours has a customer which uses the Avaya IP500. It
features some kind of "directory service" -- a phone book. This
phone book also has the feature that it only does lookups if no
name is already present:

From:
http://marketingtools.avaya.com/knowledgebase/businesspartner/ipoffice50en/mergedProjects/manager/directory_services.htm
(yes, you need a login, I don't have it either)

> Name matching is not performed when a name is supplied with the
> incoming call, for example QSIG trunks.


This means that for SIP calls, the name matching is not performed
when the "display-name" part of the From-header is set.


Unfortunately, chan_sip does not allow the CALLERID(name) to be empty.
If it's empty, it sets it to the CALLERID(num), so you get:

From: "0123456789" <sip:0123456789 at server>



Quick ABNF refresher:
