[OpenSIPS-Users] regex extract value from $ru

[Satish Patel]

Following is $ru and i want to extract following  sip:sipprovider.com:5060

sip:123456789 at sipprovider.com:5060

to

sip:sipprovider.com:5060

I am using following regex but its not working, does following make sense?

 $var(z) = $ru;
        $var(z) = "s/[^:@]*@//";
        xlog("My regex $ru\n");
