[SR-Users] Kamailio presence

We have tried all of your suggestions, but still not getting any light
changes on the watcher.
The basic problem seems to be that the watched phone sends PUBLISH
packets to the server, but the server does not send NOTIFY packets to
the watcher phone.
We are seeing the following error in the logs every time the watched
phone changes status:
DEBUG: presence [notify.c:1263]: publ_notify(): Could not find subs_dialog
We are running Kam 4.4.2
If anybody has any ideas what could be causing this, let me know.
Thanks in advance, Bill
