Safecom SWSIP-1000

I realise that this isn’t related directly to asterisk but I can’t find anywhere better to ask about this.

Does anyone have a Safecom SWSIP-1000 and can answer a question about missed calls being saved in the phone with the callers ID/number?

Reason I ask is that my current phone shows the number when someone calls, but it doesn’t save the number in the missed calls list. Its seems to want an IP address, which is a bit pointless when all calls are routed through my asterisk server, and it only ever says ‘IP Unavailale’ anyway…

For anyone that has a wireless voip/sip phone that does save he numbers in the missed call list, mind letting me know, as I’m looking for a new phone.
