Hello, serusers!
I am trying to add support to our SER routing to do the right thing
when users add extra digits to phone numbers. We have silly users
trying to dial 1-800-JABBER-WOCK type numbers, and they don't know to
stop dialing after the "W", since you don't need to on a standard
analog line.
It seems like this would either require a reg-exp back reference
(ie, \1), or a while loop and a function like strip() that works on
the other side of the user portion of the SIP address:
try subst_uri from the textops modules.
Example from textops/README:
( subst_uri('/re/repl/flags') ):
if (subst_uri('/^sip:([0-9]+)@(.*)$/sip:3463\1@\2;orig_uri=\0/i')){$
...
while (uri =~ ^sip:[1-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]) {
endstrip(1);
}
Are any of these functions available, but not documented? I've found
the language reference/Admin's guide to be a bit obscure at times for
discovering these sorts of things. Or can anyone suggest another way
to truncate the number down?
Also, as long as I'm writing in: are there any minimum and maximum
quantifiers (ie, [0-9]{3,5}) available in SER? It's hard to read code
that's 90% repeated character classes!
Yes, they should work in all the regular expressions.
(e.g.: uri =~ "sip:[0-9]{2,7}")
