[Lab] Familiar with virtual office telephony options?

[Michael Lechasseur]

Hi,

I'm investigating migrating our existing landline number/fax/toll-free 
to a virtual office that would have to follow our 4 office workers to 
landlines/cell/softphones/SIP phones. Also provide messaging service 
when we're not available. Auto-attendant. FAX reception.

www.ringcentral.ca seems to fit the bill.

Any other services that I should consider? or avoid?

I'll need user friendly access and config for the end user, and lot of 
configuration options, routing and scheduling rules for the sys admin.

We're a REALLY small office; 2 full-time and 2 part-time with a budget 
of about $100-$150 a month (or less?).

Thanks for pointing me in the right direction..

Michael
