Routing a call to an ivr extension (Dial Plan)

1. Brekeke Product Name and Version:
Brekeke PBX, Version 3.16.5.0/576.2, Pro

2. Java version:
OpenJDK 64-Bit Server VM, Version: 11.0.23

3. OS type and the version:
CentOS Linux release 7.9.2009 (Core)

4. UA (phone), gateway or other hardware/software involved:
None

5. Your problem:
We want to route incoming call to a pre-recorded audio file but getting User busy (17).

Dial Plan (for testing we are routing all incoming calls to extension 1234)

Matching Patterns:
$request = ^INVITE

Deploy Patterns:
To = 1234@192.168.x.x:5056 (Brekeke IP Address)

Would you kindly advise how to deal with this?
Thank you.

Are you using Brekeke SIP Server aside from Brekeke PBX?
Or is it a SIP Server bundled in Brekeke PBX?

Hello James,

We have SIP Server bundled in Brekeke PBX.
Sorry for my late reply.

If it is the bundled SIP Server in Brekeke PBX, you don't have to add or modify any DialPlan rules. The default DialPlan rules make all calls go to the PBX.
Instead of tuning DialPlan, let you use IVR in Brekeke PBX to meet the requirement.

FYI:

Hi James,

Thanks for sharing below details.

I have disabled the custom dial plan and kept default rules enabled only. I have also created the ivr extension as described in your link below. The calls are passing & matching "To PBX" rule:

Matching Patterns:
$request = ^INVITE|^SUBSCRIBE

Deploy Patterns:
$pbx.in
$auth = false

But we are getting User busy (17) and ivr message not playing. I am not sure if it is related to configuration issue or something else. We want all incoming calls to play the uploaded ivr greeting message.

Have you made users in the PBX?
https://docs.brekeke.com/pbx/brekeke-pbx-quick-start

We are not aiming to register users on brekeke for initiating calls.

We have a voice switch which will forward certain dialed numbers to our Brekeke PBX to play/run pre-uploaded ivr voice message.

For this we've created an ivr extension with uploaded audio file. When passing the calls to brekeke we are getting User busy (17) and ivr message not playing. Please note that we have disabled authentication for register & invite towards brekeke from our voice switch.

Mansour

Hi Mansour

On PBX, please try to create a new ARS route which forwards inbound calls to your ivr extension "3002".


Matching pattern:

To: sip:3002@

Deploy patterns:

To: 3002

Hi Brett,

Many thanks... It worked.
Have a nice day.
