* enum -
support for query on the originating side, useful in
PSTN
inbound processing
Could you send this patch to the mailing list and cc Juha?
Attached.... but... this is one of our crazy-experimental stuff. I
mean I haven't yet figured it our what to do with multiple response
or what is the final list of things to change in the message, so it
looks a bit messy to be merged in the master now.
As a bit of background info, this thing is useful when you have some
sort of PSTN access gateway that would proxy all calls towards a SIP
network. The node in charge of deciding the what-next part is called
in IMS related terminology a TRansit Control Function (TRC or TRCF)
and I have also attached a sample cfg for such a node. The advantage
of doing also enum_orig() is that this node can decide, based on ENUM
configuration, whether to trigger or not an originating leg
processing in an originating domain proxy. Or putting it in another
way, this provides the glue to have originating SIP services for PSTN
UEs.
If you just want to make ENUM lookups on the caller's number you can
also use K's enum module:
It is very flexible and allows you to make ENUM lookup with a pseudo
variable - which can be anything.
