I tried using Google Voice at one time to save toll charges on domestic
calls. Too frustrating because many of the family and friends I called
didn't pick up because they didn't recognize the caller ID. I always
left a message and told them to please call back on my usual landline
which I provided as part of my message. However, when many of them
called back, they'd call the Google Voice number but usually my PC was
off so no one picked up their call-back. I had more success when I
needed to make a toll call to a business or a government office. Those
numbers usually picked up or were more attentive to my request to return
my call on my usual landline. That obviously says something about many
of my friends and family members!
One thing you have to understand about VoIP is that there are multiple
companies involved: Comcast for internet service, the VoIP service
provider, and the CLEC which provides the phone number and network
interconnectivity. The subscriber deals with the VoIP service provider;
they in turn buy service in bulk from the CLEC, which is typically
bandwidth.com.
If you already have a phone number but just want to change service
providers, then take advantage of porting out the number. If you don't
have a phone number, then let the phone number be assigned by the CLEC.
I have two Google Voice numbers that are specific to organizations that
didn't already have phone numbers. I allowed the CLEC to assign numbers.
I also have a VoIP provider. At some point, if Google Voice gives me
lousy service, I'll port out the numbers and port them into my account
at the VoIP provider. It'll barely increase my annual costs, which are
between $75 and $100.
Since you specifically didn't want the new telephone number, you should
have ported out your old number and ported it in to your Google Voice
account. Then they'd have recognized who was calling.
Any type of phone number may be ported out as long as the current phone
service provider participates in number porting. The losing carrier must
have a record of the service address on your account and you must give
this service address to the gaining carrier. The gaining carrier must
find a match in the losing carrier's database, else the port out will be
denied.
Yes, I realize that these days of virtual phone service that "service
address" is meaningless with respect to a phone line being installed and
terminated at a phyical location given that handsets and terminal
adapters are portable and can be used anywhere. Nevertheless, the losing
carrier MUST have a service address in its record of your account. No
one checks that this is the address at which the terminal adapter is
connected to Internet service.
Some rural carriers are exempt from number porting by the state public
utility commission. Cell phone number can usually, but not always, be
ported out. Because a phone number (except for a toll-free number and a
few other exceptions) is tied to telephone switch geography, the gaining
carrier must ALSO be active in the geographic area the original number
was provided in. Typically, that means if you move, almost any number
can be ported from traditional land line to VoIP or cellular, but the
reverse is unlikely to be true.
