[OpenSER-Users] avp_subst and regex

[Daniel-Constantin Mierla]

Hello,

indeed there seems to be an issue with interpreting the strings in 
config file, before getting to avpops function parameters. When the 
config file is parsed, inside the string, \[0-7]{2,3} is interpreted as 
a ASCII code in octal base and replaced with its code. Try:

avp_subst("$avp(s:fromuri)","/^(sip:)([134][0-9]{4}@.*)/\\\x01121285\2/");

However, in 1.2 you can achieve same by:

$avp(s:fromuri) ="sip:121285"+$(avp(s:fromuri){uri.user}) + "@" + 
$(avp(s:fromuri){uri.domain});

Cheers,
Daniel
