The Softswitch "authenticates" (if you can
call this authentication ;-( by looking at the
Contact header and comparing it to its database of numbers assigned to provisioned SIP
Servers.
I therefore need to be able to specify a rewrite of the Contact header to
replace harry@<Contact IP:port> with 12345621@<Contact IP:port>
when the callee is of the form <number>@<whatever>
I am aware that this would be strictly speaking not proxy but rather B2BUA behaviour, but
would still be
interested to know whether anyone has a solution to this problem or whether we need to
hack one ourselves.
You can try a brute-force approach, create a regular expression that
will match Contact: harry@<Contact IP:port> and replace it with
12345621@<Contact IP:port>. You could use textops subst function for
that.
E.g.: subst('/^(Contact: *)harry(@.*)/\112345621\2/i');
However you will need to have one subst for each user hard-wired
in your ser conf.
