Any guidance would be appreciated. Hope you are all good cheers John

Thanks for the response. Yes installed UC edition without any issues. I was surprised to see it set with UDP as well. Can certainly change the setting to TCP. And yes followed your stuff as well. I sort of think there are firewall issues going on as well.

Changed a few things and getting a better result as getting a SIP issue so now talking to the right server etc.

Error in logs are :
Oct 15 12:55:26 [WARN ] PHN: Could not resolve host >ceresseeds.com.au<

Tested the login no problems with that it works from a Skype client.

Very frustrating as it seems most settings are in line with your stuff
