[Users] query on openser

Hi, I have installed openser v1.1.0 on Linux system. I have problem checking if "Route" header contains the "username" of Req-URI as below: Req-URI will be like "sip:7267261000@<domain>" and Route header will be like "<sip:termdoneatscsf_7267261000@<domain>;lr> # To get the RURI I did like this avp_write("$ru/username", "$avp(UNAMEOFRURI)"); avp_print(); # To get the Route Header, I did like this avp_write("$hdr(Route)", "$avp(ROUTEUSERNAME)"); avp_print(); Now, what is the best way to check if $avp(ROUTEUSERNAME) contains $avp(UNAMEOFRURI)? I tried as below, and it gives error "regexp requires string value" if(avp_check("$avp(UNAMEOFRURI)","re/$avp(ROUTEUSERNAME)/gi")) { log(1, "Usernames of RURI is found inside Route header."); } else { log(1, "Usernames of RURI is NOT found inside Route header."); } Instead of avp_check, I tried to use search as below: if(search("^(Route):.*$ru/username.*")) { log(1, "Usernames of RURI is found inside Route header."); } But, it didn't work either. Please suggest what is the best method to do this? Thanks, Vivek __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
