Sip plugin with openjsip

Has anyone got openjsip to work with the sip plugin

I’ve got everything installed. In the sip phone mappings, I setup a user and it tested green; When I try to connect using spark I get a ‘Failed to start phone’ message.

When I check the server logs, I can see the log showing the login from when I tested the account in the admin console; but I see no logs from when I try to connect with spark.

Any ideas on what to trry or where to look for more information.

Thanks in advance, John
