[asterisk-biz] Wireless SIP phones?

[Michael S. White]

Hi Lane...

Snom is also supposed to have a repeater for those in the near future.. Just
in case you need a bit more range.

I currently use 1 base station with 8 M3's and have yet to have a problem.
All 8 phones have their own ext's.  I will be converting another location to
VOIP and have more M3's to use.
