I had (and still have) similar problem. Once SPA 2000 registers with *
it all works well for few minutes. After that all incoming calls are not
answered by SPA 2000. 
Is that what you mean?

If so, I have temporaraly got SPA 2000 to re-register every 3 minutes.
This seems to work at the moment.
(Sipura tech support known about this problem for about 6-8 weeks now,
but I am still to hear from them).
