When anyone in PSTN world calls to +34999000222 the

OpenSer from a gateway in an INVITE like:
INVITE sip:+34999000222@gateway SIP/2.0
To: <sip:+34999000222@gateway>
why gateway in the host part? isn't host more likely the ip or hostname
of your proxy?
The info about the called PSTN number is just
available in "To"
header, so a
way to get different behaviour for each associated PSTN number is
matching "To" URI.
Is common to do it? which other alternatives are there?
your proxy could add other headers to the invite, such as diversion or
history-info, if your sip ua knows to look for them.
