[Serusers] lookup(): '' Not found in usrloc

[Kim Culhan]

A UA is trying to send NOTIFY:

U 1.2.3.4:56839 -> 5.6.7.8:5060
NOTIFY sip:machine.foo.com SIP/2.0.
Via: SIP/2.0/UDP 1.2.3.4:56839;branch=z9hG4bK-ee80efbb.
From: TPA - PSTN <sip:9876 at machine.foo.com>;tag=ddf83b1b7d0b3b06o1.
To: <sip:machine.foo.com>.

Max-Forwards: 70.
Event: keep-alive.
User-Agent: Sipura/SPA3000-2.0.13(GWg).

The reponse is:

>From the logs we see among other things:

Feb 25 08:09:13 machine /usr/local/sbin/ser[15425]: lookup(): '' Not
found in usrloc

Can anyone tell me why the user is not found ?

Any help here is greatly appreciated
