[AusNOG] mobile phones coverages alternative

[Joseph Goldman]

My thought would be a local (preferred) or hosted (if connectivity is 
decent) VoIP server and a SIP client on each phone (assuming smartphones).

However, to *receive* calls, the phone will need to be set to call 
forward to your VoIP server. From what I can think of, this will mean 
putting up with 1 of either of these 3 issues:

     1) Users will have to turn call forwarding on and off each time 
they come in/out.
     2) Users set call forward on no answer to VoIP server, instead of 
Voicemail. If they want Voicemail at all then the VoIP server will need 
to handle it full stop
     3) Call forward always set to on, and the clients register via 3G 
chewing up 3G data with each call. Problem with this is, the Mobile 
Service is charged for each call diverted on as an outgoing call, so 
this could be costly when all added up.

  There may be scenario's or setup's I haven't considered. My personal 
favorite would probably be number 2.

Thanks,
Joe
