[OpenSIPS-Users] is_request(), is_reply() functions in OpenSips

[Vitalii Aleksandrov]

I'm also used to have is_request()/is_reply() and when switched to 
opensips started to use following helpers:

route[IS_REQUEST] {
         if (route(IS_REPLY))
                 return(-1);
         else
                 return(1);
}

route[IS_REPLY] {
         if ($mb =~ "^SIP/2\.0")
                 return(1);
         else
                 return(-1);
}


Of course checking $rs should be really better that my regexp.
