Re: Hm, picocells .... can those work with SIP?
"make my SIP numbers available on my mobile"
Just buy a decent mobile, mine has SIP built in (its an SGS4), so I get my sip calls on my phone no problem...
I also have a quite nice Gigaset DECT SIP phone for my office, that handles SIP & POTS calls.. it also has built in bluetooth and is basically very nice, so i'd argue against all sip handsets being crappy
One thing I would like is a way to route the POTS lines I have to SIP without needing a separate server.. also I'd like my phone company to allow UMA so i don't need their crappy femtocell when out of range!
