[Serusers] PSTN connectivity - sr-users

20 Jun 2006

Hi SER users ,

                      At present iam using SER-0.9.6 as proxy,registrar ,and
the sip to sip calls i tested are o.k and is perfectly going and now when i
tried to connect to PSTN it showing 500 internal server error i dont
understand whether it is the mistake of cisco sip gateway or SER 's

                     here is the sip messages which i get when i tried to
call SIP to PSTN .  I HAD GIVEN SIP TEST CLIENTS USER ID AS 32331000 AND THE
LOCAL PSTN NO. ARE LIKE THIS :eg: 22458792

My Domain/Realm=81.21.33.35

and iam using onsip ser.cfg as the ser config file

        if (uri=~"^sip:011[0-9]*@") { # International PSTN
        route(4);
        route(5);
        break;
        };

       if (!lookup("location")) {
        if (uri=~"^sip:[0-9]{8}@") { # Domestic PSTN
                route(4);
                route(5);
                break;
        };

and the pstn connectivity lines are like this:

and here are the sip messages when i tried to call pstn number

my pstn gateway which iam testing now is 81.21.38.21
