[SIPForum-discussion] outgoing phone number

[Renan Panes]

Hi Dave,

800 Toll-Free Numbers, like Rob have just said, are not given out as a 
subscriber number. A Toll-Free number is a virtual or a pesudo number normally 
assigned by a PSTN network service provider usually, but not limited, for 
business use. Each Toll-Free number has an equivalent hidden number where all 
the calls to the Toll-Free number is terminated, which is nothing but a 
subscrber number, too.

All calls originating PSTN network, to the Toll-Free number is then routed to 
its equivalent PSTN hidden number.

sample call flow:

Local California Call --> 800-SIP-FORUM-CALI --> Local California (Hidden) 
Number --> Network Provider.

 
You cannot use the Toll-Free number as an outgoing CLI since, as aforementioned, 
it is nothing but a virtual or a pseudo number. However, you can use any 
available subscriber number to do so.

What do you mean anyway with setting up the headers as such not to violate any 
rules?




Best Regards,
 
Renan Panes

One thing I'd like to point out.  Toll Free numbers  are not, in my experience, 
ever given out as subscriber numbers.
 
A user with a subscriber number can get an 800 number  for business, personal 
use, etc...
 
The PSTN will normally translate that 800 number to the  subscriber  number.  
 
What I've seen for 800 service is the request-uri  contains the translated 
number and the To:  field will contain the 800  number.
 
Is this not the case for you?

What do I do if I have a subscriber that only has a toll-free  number and the 
subscriber places a call to the PSTN?  What do I use for the  outgoing phone 
number if the PSTN will not accept the subscriber’s toll-free  number as the 
outgoing phone number?  How can I set up the headers so that  I do not violate 
any rules?
