Hi, maybe this question is a bit off-topic so I'm
sorry for that.
My question is about SIP providers using OpenSer that associate PSTN
numbers
to their local clients (SIP accounts):
Usually the client must register to OpenSer in order to receive
calls. Then it
will appear in location table with "Contact=sip:clientX@IP".
Suppose clientX has two PSTN numbers associated in a ENUM entry:
+34999000111
+34999000222
When anyone in PSTN world calls to +34999000222 the call will arrive
to the
OpenSer from a gateway in an INVITE like:
INVITE sip:+34999000222@gateway SIP/2.0
To: <sip:+34999000222@gateway>
The OpenSer will do the lookup in location table and finally send
this INVITE
to the clientX:
INVITE sip:clientX@IP_clientX SIP/2.0
To: <sip:+34999000222@gateway>
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?
You can also add multiple aliases to the same user. All INVITEs to
different aliases will be sent to the resolved user.
