Re: [Users] Problem with avp_check

Hi Jose,

I think your regexp is not correct - you need to force the end of string, otherwise only a substring (prefix) will be matched.

try avp_check("$fU","re/^[0-9]{10}$/g")

Hi thanks Andrei, I tried with your recomendation but I obtain the same result, if $fu is: 012345678901, then "To-username -012345678901-" is inserted

if(avp_check("$fU","re/^[0-9]{10}/g")) { insert_hf("To-username: -$rU- \r\n", "Call-ID"); } else { sl_send_reply("400", "Peticion Erronea, numero invalido"); };

Hi Jose,

the FM operator in avp_check is not for regular expressions - FM is a
file matching- like operator (like "sip:*@domain). See "man 3
fnmatch".

if you want to check against an regexp, you need to use the RE
operator.
See:
http://www.openser.org/docs/modules/1.2.x/avpops.html#AEN384

as RE op does not support an AVP as right operand, you should try:
if(avp_check("$fU","re/^[0-9]{10}/g")) {
