Regular expression with "\d" operator.

[tuctran]

1. Brekeke Product Name and Version: Brekeke SIP SEVER, 3.4.x.x release

2. Java version: 1.8.0_45

3. OS type and the version: 8.1

4. UA (phone), gateway or other hardware/software involved: does not master

5. Your problem:
I create below rule to check a NOTIFY message then inform to user for a number of new voicemail messages come to his mailbox. A number of new voiemail message is filtered out from NOTIFY message by this expression "expression $body("Voice-Message: (\d+)/") = (.+)". But this expression always returns a null value instead of a number (4) as I expect from this body content "Voice-Message: 4/0 (0/0)".
Could any one tell me if any thing wrong with the expression. Please see below for detail of the problem.

Thanks,

Create below dial plan rule:
Rule name: "PN3_NotifyVoiceMes"

Matching Patterns

$request = ^NOTIFY $getSIPuser(To) = (.+) $pn.user("%1") = true Content-Type = application/simple-message-summary $body("Messages-Waiting: (.+)") = yes $body("Voice-Message: (\d+)/") = (.+)

Deploy Patterns

&pn.notify.user = %1 &pn.notify.message = You got new voice message $pn.notify.counter = %2 $continue = true

*Below is actual NOTIFY message I got.
============
NOTIFY Message:
NOTIFY sip:1003@127.0.0.1 SIP/2.0

Content-Length: 85

Messages-Waiting: yes
Message-Account: sip:8@192.168.0.3
Voice-Message: 4/0 (0/0)


=> With the input "Voice-Message: 4/0 (0/0)". The expression "$body("Voice-Message: (\d+)/") = (.+)" should return "4" instead of "null"

[Harold]

Which Voicemail system are you using?
Is it Brekeke PBX? or 3rd product?

If you are talking about Brekeke PBX, let you post the question at the PBX Forum. http://www.brekeke-sip.com/bbs/viewforum.php?f=33

if you are using 3rd product, let me know the product name.

[Harold]

Have you applied the DialPlan rule?

According to the log, you used $body("Content-Length: (\d)") instead of $body("Voice-Message: (\d+)/").

Yes, I have.
Sorry I posted a wrong log file. Please see below for a proper one.

Try \\d
Since it is within a "", you need to escape \ with one more \.

$body("Voice-Message: (\\d+)/") = (.+)

Thanks Harold,

It works now.
