SIP Providers: Spoofing An Existing POTS Number?

For my Skype setup, I have Skype spoofing our land line number.

That way, when we call somebody who filters incoming calls based
on the number of the calling phone their equipment sees the same
phone number it always has and we don't have to do anything more.

I'm guessing this is service-dependent and maybe even
country-dependent.

From USA-ian perspective, is there any chance of duplication the
abovementioned functionality with a SIP provider?

 

In the other thread Theo mentioned a provider called Betamax
They offer umpteen similar but slightly different packages and your
choice will be dictated largely by the mix of international calls you make.
I have used this company for all my outgoing calls for several years, the
"clone" I currently use is called smartvoip.com.
The two websites below will help you identify the one that you might use.

Beware of those that charge a connection fee, that isn't reflected in the charts.

Now, to answer your question. All the Betamax clones I have used allow you
to present any number you like. You have to use their dedicated softphone application
to do this there is a confirmation button that initiates an automatic call to the number
you choose as a CLI. When you answer the call you hear a 4 digit code which you
have to type into the softphone. This proves you own the number, or at least have access
to it. So there is no problem presenting your cellphone, landline, or a VoIP number
you might have signed up for with another provider.

Other providers might allow you to present the number of your choice too, but
I understand they sometimes require documentary evidence you own the number
like having to send them a paper bill.

 

Unfortunately it is not reliable. Sometimes it presents the number
that you've assigned, generally it shows as International on a BT
line. (Using SMSListo.)

 

Per Graham.:

That's a one-time setup procedure, right?

Thanks for the links to your providers.

I think I'll pull the trigger on the Cisco SPA3102 today.

 

I've not had that problem with voipcheap.co.uk, voipcheap.com, smslisto.com, or smartvoip.com
If I try to present a non-uk number however, BT will usually flag it as "unavailable"
(no surprise there) but the mobile networks generally accept it.

 

It is one time. Once you have verified that you own the number it is
permanently available in a list and you can remove the SmartVoip (or
other Betamax) software client from your computer.

I have never had a problem presenting my chosen CLI when using either
SmartVoip or SMSListo.

 

I use voip.co.uk - and can present any of several numbers (landline,
mobile, etc.) once I have proved to them that I own the number.

I usually present my landline number so that anyone who uses ringback
comes back to me on the landline (I prefer to use VoIP for just outgoing
calls).

Using voip.co.uk's on-line account management system, it is very quick
to change the presentation number to one of the other pre-authorised
numbers (but it's not practical to do it on a per-call basis).

Per (PeteCresswell):

FWIW, I signed up with CallCentric.

Their response to my request to have my home phone number sent as
CallerID was so fast it made my head spin.

Also, I find their user "Home Page" tb quite convenient/intuitive
- especially the ease with which I can add dollars to my account
balance.

 

Are voip.co.uk starting to accept private customers again? I have two
active accounts with them but they were created years ago.

Last I heard was they were only accepting commercial accounts.

 

I think that's probably right - I can't see any mention of private
customers on their website - so it's not an option for anyone who is not
already with them.

I mentioned them as an example (the only one where I have any direct
experience) of a VoIP company which allows you to specify your outgoing
CallerID - with the expectation that others would be similar.
