This is my 2nd Soho account to test the sip registration. I am trying to register sip:ville2500-100@217.195.32.11. It failed to register on Nokia and also on Sipura.
Same I tried to with my 1st Soho account richard99-100, it failed too.
My Premium account has no problem to registered either Snom, Nokia E61 or Sipura.
I suspect the it has something to do with account name, both Soho account are alpha-numeric, but Premium is only alpha.
Seems this alpha-numeric account name is some how failing to register.
The bug has been fixed. It had nothing to do with the account names. Reason was that these accounts had been disabled before a software update on Jan 24th, 2008.
