I guess the proper answer is: this is an option of the dialplan of
the pbx.<br>
<br>
But based on experience so far, the pbx doesn't sent the call out to
a provider when the call is to another extension in the same pbx.
More, in many cases there is not 1-to-1 relation between pbx
extensions and PSTN numbers. Typically a pbx has more extensions
than PSTN numbers. PBX extensions are short numbers allocated as
needed, while PSTN numbers are bought based on estimation of use,
being mappend to some internal pbx extensions.<br>
