Many of my company's mobile 100 has worn out and since Alcatel doesn't provide mobile 100/200 any longer, I want to use some other DECT phones. From here I know Siemens S45 or E45 can do the job well. But I don't know how to register these DECT phones. After reading Siemens gigaset S45 manual, I find S45 can register to at most 4 bases, and it needs base PIN and base number during the registration procedure. When registering a mobile 100, I choose "N" when asked which base to register, then it registers to all the base stations. By using dectarea, I found there are 16 base stations in my company. So, what should I do after choose GAP handset type and run dectinston -g command, how do I deal with these base number and base PIN issue. By the way, I have tried to register the mobile 100 in GAP mode, its procedure is just like the GAP+ mode, no need of base number and base PIN.
