VOIP Beta - Can't connect - Now fixed!

[#1]

I am using a PAP2T IPA
I can connect ok using the current system.
Please tell me what I'm doing wrongwhen changing settings to use trial system!
I have changed on the following things:
Proxy & Outbound proxy changed from sip.plus.net to nat.plus.net:5082
Auth ID & User ID changed to new SIP ID as advised
Password changed to new password as advised
All other settings as before e.g stun server etc.
I get a can't connect to login server error from the IPA.
Thanks
Paul

I don't know your device at all, but I can't see any mention of SIP domain server sip2.plus.net.

Yes, If I have to put the domain in somewhere - I don't know where it should go !

On my similar-ish Sipura SPA-1001:
Proxy: sip2.plus.net
Outbound Proxy: nat.plus.net:5082

That's cracked it!
Thanks very much
