[Freeswitch-users] [FS Unable to evaluate large regex]

[Ken Rice]

This is one of those things where you probably need to be looking at either using more regexes or even looking going beyond the basic dialplan and into things like xml_curl or other more advance call processing mechanism

Hi Brain,

With above given example, i want to match 03135082344, that went perfect, but when i append some more REGEX with this like below

 

(^(0092|\+92|92|0)312(9([0-9][0-9])|5([0-9][0-9])|0(0[59]|1[59]|5[0-9]|8[56789]|9[0-9])|1(5[0-9]|8[56789]|9[701234569]))[0-9]{4}$|^(0092|\+92|92|0)313(9([0-9][0-9])|5([0-9][0-9])|0(0[59]|1[59]|2[6789]|5[01234567]|8[56789]|9[01278934])|1(2[6789]|5[01234567]|8[56789]|9[0-9]))[0-9]{4}$)

 

i am unable to match 03135082344, and its getting failed.

 

Cheers

What exactly are you trying to accomplish with this and what are some examples of what you're trying to match?

Hi users,

i am getting some weird regex problem with my FS, if you have your regex length in more then 3000 characters if does not accept that in the condition, i split my regex in around 2000 characters, now i can see that FS is unable to resolve the Below Regex in the condition( i have a lot of other concatenated with that)

 

^(0092|\+92|92|0)313(9([0-9][0-9])|5([0-9][0-9])|0(0[59]|1[59]|2[6789]|5[01234567]|8[56789]|9[01278934])|1(2[6789]|5[01234567]|8[56789]|9[0-9]))[0-9]{4}$

 

But when i try that alone in the condition that works, i even tried to execute the whole in online regex tester and that did worked, but not working on FS.

There must be a length of regex in condition that FS can evaluate,

So

i) i want to know that length so i can split my regex even shorter.and FS can evaluate that.

ii) How FS people will look into this issue, so they can guide/fix this issue.

 

Regards

Abbasi
