[Serusers] enum module error ser2.0

Hi! I was trying to utilize the enum module of ser but whenever I try to do the check for the user part of the request uri I get the following error: ser@sen:~/ser/ser-cvs/proxy$ ./ser -c -f ser.cfg 0(5401) parse error (721,14-15): unknown command, missing loadmodule? I have the enum module loaded and the line for this happens is: if (is_user_from_e164()) { I also tried is_e164() which I found in the module header file but with the same result. it this is not going to work how can I make the check by hand? for instance having such uri sip:+4822102@domain.com will somthing like this work: uri=~ "sip:+[0-9]{7}@.*" ??
