[PreViking-devel] "standardised" method of doing number translation

[<za...@gr...>]

Aymeric

Correct me if I am wrong, but the number translation we had proposed of
sending a set of tags such as:

TRANSLATEADDRESS address=02081234567 srcformat=uk destformat=carrier carrier=BT

which may have returned:

200 translatedaddress=442081234567

could be done by dynamic generation of a URL and sending to a SIP
redirect server:

I guess the URL for the above example could be:

uk-...@bt...

and PreViking would send:

INVITE uk-...@bt...

The redirection proxy would return a 302 Moved with the redirection
address as:

442...@ps...


Am I barking up the wrong tree or is this a valid use of SIP?

The dynamic number translation would be used by PreViking to figure out
what to dial.

A good example of where it may be useful is, lets say you have a calling
card service in the UK.  You want the users to dial a number as if they
are in the UK, but the carrier you may use to actually place the call is
based in USA so expects a number as if dialled from the USA.  Some sort of
number translation is required, especially if there are many carriers
requiring different dialling methods.
