Well, you decide where to strip, depending on your dial plan. [0-9]{10} matches exactly 10 digits.
914082743304 is twelve.
if (uri=~"^sip:1[0-9]{10}@bigu.edu") {
strip(1);
};
does not match, neither the 011 if test, so if you add strip(2); it will work (remember the ;) g-)

Greger,
thanks for the reply. I have not modified the original gateway/pstn configuration as far as digit minipulation goes. How and where would I strip the digits in ser.cfg? I tried entering strip(2) just before the if (uri=~"^sip:[0-9]{10}@bigu.edu") statement, but the config failed to start. It looked like this
strip(2) if (uri=~"^sip:[0-9]{10}@bigu.edu")
thanks,
Quoting "Greger V. Teigre" greger@teigre.com:
if (uri=~"^sip:[0-9]{10}@bigu.edu") { # Domestic PSTN probably doesn't match the r-uri you have at that point. Have you stripped 2 digits by then? g-)

hello all,
I am stuck and need your help for +xlite +ser +asterisk +pstn calls. I dial 914082743304 and get "caller Not Found". I am able to authenticate and complete sip -> sip calls, but cannot complete PSTN calls I did monitor asterisk and no reroute was offered.
please help!
