[Users] using AVPs to write into database

Hi all, I am trying to implement the call forwarding feature in openser. The forwarding part is fine. But I have the follwing scenario: Whenever a user needs to change his forwarding number, he should be able to do so from his end device only. For eg: He first presses 86 and then the 10 digit number to be forwarded. Here the 86 has to be stripped and the 10 digit number should be inserted into the call forward value column of the preferences table. Also if he wants to remove the forwarded number, he can do so by pressing say for eg: 87. on receiving this number openser should delete that value from the table. Is this possible. I tried to do the following, but somehow it does not change the value. if(uri=~"^sip:86[0-9]*@") { if(avp_db_load("$from/username", "s:callfwd")) { #check if call-fwd feature is enabled for the user log(1,"AVP condition returned true"); strip(2); avp_write("$ruri", "s:callfwd"); avp_print(); log(1,"AVP written"); sl_send_reply("200", "OK"); exit; }; }; Is avp_write the proper method or I guess avp_db_store can also help me. The avp_print() function also does not show me anything in the log. Are there any logical mistakes or I have mis-interpreted the syntax of avpops functions. Please help me in thsi regard. Thanks a lot in advance. Jayesh. --------------------------------- Jiyo cricket on Yahoo! India cricket Yahoo! Messenger Mobile Stay in touch with your buddies all the time.
