Hi
I am trying to find a way to detect if the Invite URI starts with a *.
How do I match this as ser normally sees * as a wildcard.
Regards
Jon

I'm not really enlightened in the realms
of URIs, but can a URI really contain a * ?
I was under the impression that the only allowed
characters were [A-z0-9-.] plus @ as a separator
of username and domain.

I believe SER uses regular expression type of
matching and thus * is not really a wildcard, but
rather "0 or more instances of the previous
character". Anyway to match a request-URI starting
with '*' you simply do
if (uri =~ /^\*/) { #blaha }
I'm from the OpenSER world so request-URI might
not be called 'uri'.

Almost, but the scheme is part of the URI, so it would be
if (uri =~ "^sip:\*") { ; }

Thankfully, this is IETF land and we can easily check:
SIP-URI = "sip:" [ userinfo ] hostport
uri-parameters [ headers ]
userinfo = ( user / telephone-subscriber ) [ ":" password ]
"@"
user = 1*( unreserved / escaped / user-unreserved )
unreserved = alphanum / mark
alphanum = ALPHA / DIGIT
mark = "-" / "_" / "." / "!" /
"~" / "*" / "'"
/ "(" / ")"
escaped = "%" HEXDIG HEXDIG
user-unreserved = "&" / "=" / "+" / "$" /
"," / ";" / "?" / "/"
They userinfo part of a URI may actually contain quite a lot
non-alphanumerical characters. Well, pretty much everything, really.

I would try:
if (uri=~"^sip:\*")

p.s. =~ is regular matching operator in SER config language, \* is the
RE expression for the "special character".
