Solved Inbound SIPs not going to correct extension numbers

[deano]

Hello All,

I've gone through several different posts to find a solution, however nothing seems to be working.

The Problem

I have 5 different inbound telephone numbers (Provided by Dial9), when I am calling ANY of those 5 telephone numbers they are all routing to my extension number. What should be happening is that they go to their relative extension numbers.

I have spoken to Dial9 to see if there is a problem on their side and they have had a look at my 3cx logs and not not find a problem and do not understand why my calls are not routing corrently.

My Setup

To save space, i will explain how i have 2 telephone numbers setup;

Telephone number 1: 0330 229 XXXX

SIP: I have setup 2 SIPs by advice of the provider (Dial9), the Main Trunk No = 0330 229 xxxx
Route Calls To - Extension 1000
Inbound Paraments = Call Source Identification = True and Use Both "Call Source Identification ..." = True.
Under DIDs there are no other numbers apart from the main Trunk Number.

Telephone number 2: 0161 806 XXXX
SIP: I have setup 2 SIPs by advice of the provider (Dial9), the Main Trunk No = 0161 806 xxxx
Route Calls To - Extension 1001
Inbound Paraments = Call Source Identification = True and Use Both "Call Source Identification ..." = True.
Under DIDs there are no other numbers apart from the main Trunk Number.

What I have tried

- Enabling and disabling the Call Source Indentificatoin
- Changing the parameters
- Adding/Removing Inbound Rules (currently no inbound rules)
- Contacting the SIP Provider

Dude, use 1 trunks.

The config under SIP Trunk is a catch-all.

You should add your DIDs under SIP Trunks -> DIDs, then create an Inbound Rule for each, pointing them to their respective extensions.

Thank you! Thank you! Thank you!! A thousand Thank You's.

Thats worked, I think. I'm going to do some more testing tomorrow as my team members keep getting calls from me out of hours lol.

Of course a trunk is a catch all, point traffic to an IP, let the PBX listen and figure out what number is being passed. It makes sense now.

Just conflicting information from my SIP provider who told me to setup a trunk per number, which obviously is not needed.

It's also not supported by 3CX, and not recommend by anyone unless you know what you're doing.

Obviously no surprise that all of your suggestions worked, thank you. All this has been tested.
