[Serusers] call forwarding and *21

[Kyriakos Mavromichalis]

I have done it with avpops.
User inputs *21*1*number  for forwarding to.
First 6 digits get stripped and the rest gets stored in user_preferences.
*21*2 is for dectivation and what it does is that deletes the row from 
user_preferences of the user sending the deactivation request.

		if(uri =~ "^sip:\*21\*1\*")
		{	
			log(1,"route[3]:Call forwarding activation detected\n");
			#check if cf option already exists and delete it
			if (avp_db_load("$from/username", "s:callfwd"))
			{
				log(1,"route[3]:Call forwarding option already exists, deleting it....
\n");
				if(!avp_db_delete("$from/username", "s:callfwd/usr_preferences"))
				{
					sl_send_reply("500", "Server DB error");
				}
			}
			strip(6);
			avp_write("$ruri","s:callfwd");
			avp_db_store("$from/username", "s:callfwd/usr_preferences");
			
			#replace this with number that points to IVR saying "Service activated"
			subst_user('/.*$/22693314/');
			route(8);
			
			break;
		} else if (uri =~ "^sip:\*21\*2")
		{	
			strip(5);
			log(1,"route[3]:Call forwarding cancellation detected\n");
			if(!avp_db_delete("$from/username", "s:callfwd/usr_preferences"))
			{
				sl_send_reply("500", "Server DB error");
			}
			
			##replace this with number that points to IVR saying "Service deactivated"
			subst_user('/.*$/22693314/');
			route(8);
			
			break;
		};

thanks for the help!
