[Serusers] Rewriting Record-Route headers

[Evan Borgstrom]

Hey Jan,

I've forwarded the same info off to the Vendor (incl. full packet dumps
from ngrep) to see what they say, but perhaps it's something with my
rewriting code. Anything you see that's not as it should be.

# 7 digit call - append area code of caller
if (uri=~"^sip:[0-9]{7}\@.*") {
        exec_dset("
          /bin/echo -n 'sip:' > /tmp/.areacode.$$;
          /bin/echo -n $SIP_HF_CONTACT | /bin/cut -c '2 3 4' | /bin/tr -d '\n' >> /tmp/.areacode.$$;
          /bin/echo $SIP_RURI | awk -F'sip:' '{print $2}' >> /tmp/.areacode.$$;
          /bin/cat /tmp/.areacode.$$;
          /bin/rm -f /tmp/.areacode.$$;
	  echo>/dev/null;
	");
};

# 10 digit call - append 1
if (uri=~"^sip:[0-9]{10}\@.*") {
	prefix("1");
};
