Access a Variable across the Dialplans

1. Brekeke Product Name and Version:BSS Adv Ver 3.5.2

2. Java version:1.8

3. OS type and the version:RHEL 6.1

4. UA (phone), gateway or other hardware/software involved:SIPP

5. Your problem:
I need to save the value in a variable and use the variable in the next dial plan.
In the first dial plan, I want to run a webget and retrieve the value from a remote server. If the returned value is 404 then I want to get the action to 404. In the next dial plan I want to check if returned value is 503 then I want to set the action as 503. If the length of the retuened value is more than 3 then I wan to terminate the call as explain in the last dial plan.

Rule-3: Route Call

[Deploy Patterns]
To = sip:%{&my.variable}@192.168.2.130

Thanks and appreciate your help.

This works perfectly fine but I am not able to pass on the INVITE Parameters. to Leg-B

for example I recieve the INVITE as :

INVITE sip:+111@192.168.2.5:5060;user=phone SIP/2.0

and I am sending out the INVITE as

INVITE sip:+222@192.168.2.55:5060 SIP/2.0

Change Rule-3 as this.

[Matching Patterns]
$math.gt($str.length(&my.variable),3) = true

[Deploy Patterns]
To/uri = sip:%{&my.variable}@192.168.2.130

Appreciate your response.

One final request. How to enhance the rule-3 with failover option
For example, first attempt should goto 192.168.2.130 and in case .130 does not respond or respond with roll over cause code then second attempt should be attempted to 192.168.2.131

FYI:

To/uri = sip:%{&my.variable}@192.168.2.130
$session = failover sip:%{&my.variable}@192.168.2.131

Math.gt function is throwing java exception. Following is the output from the dial plan log.

Pattern: $math.gt($str.length(&my.variable),3) = true
Input: $math.gt($str.length(&my.variable),3) = null
Result: false

put a double-quotation around 3.

$math.gt($str.length(&my.variable),"3")

Math.gt problem got resolved, thanks for your help.

Following helps to fix the parameters in the TO header but it does not help to replay the paramaters in the INVITE request.

Deploy Patterns
To/uri = sip:%{&my.variable}@192.168.2.130


Incoming Packet INVITE sip:+11111@192.168.2.5:5060;user=phone SIP/2.0
Outgoing Packet INVITE sip:+22222@192.168.2.130 SIP/2.0

How can I main the INVITE params?

Something wrong in SIP packet or settings.
Check the DialPlan history whether "user=phone" exists or not.

Also can you paste all of DialPlan rules here?

Here is complete rule-3


Matching Patterns
$math.gt($str.length(&my.variable),"3") = true

Deploy Patterns
To/uri = sip:%{&my.variable}@192.168.2.130
$session = failover sip:%{&my.variable}@192.168.2.131
&failover.timer.inviting = 1
$b2bua = true
$rtp = false
$ifdst = 192.168.2.5
$ifsrc = 192.168.2.6

Did you check the DialPlan history to see whether "user=phone" exists originally?

If yes, enable "DialPlan" at [Diagnostics]->[Debug Logs] page and check why it is removed.

Yes, I did. I copy/pasted from the the dialplan history.

Have you checked the log too?

Add the line below at [Configuration]->[Advanced] page
