Hi all,
I've just been setting up such a phone with * and I'm facing some
problems.
At this time there is no customized extensions & others, so I use extension
8500 (voicemail) in default config.
What I get when this extension is called from the SNOM is pasted below. The
phone ignores *'s invites and * sends a "BYE" to it. Please note
the IP in
the "Contact" header... * also send on a port the phone doesn't
seem to be
listening on.
* is running on 192.168.35.4, the phone is 192.168.35.110.
Thanks for any help.
