Solved Call from Multiple DID from provider DIDX goes to same ext

tsww · Dec 21, 2020

Hello Dear,

I am new to 3CX. I have multiple DID from DIDX and I am trying to test with 3CX. I did set up as per below.

- Inbound trunk setup
- Two ext 1000, and 1001
- two DID: DID1 and DID2
- I did set up Direct Inbound Dialing (DID) for DID1 to 1000 and for DID2 to 1001 under extension.
- I have created 2 inbound rules. DID1 route for 1000 and DID2 route to 1001.
- I have also configured at the provider side to DID1->1000@my3cx and DID2->1001

No matter what DID I call, call always go to ext 1001.

Did research and reviewed other posts with a similar issue and tried different settings under SIP Trunks>Inbound Parameters> Call Source Identification. But none is working. When I select "Use both "Call Source Identification" rules and "Caller Number/Name -> CalledNum" field mappings (Note: Disables catch all routing capability)"

I don't receive a call at all.

Does anybody use DIDX as a provider, would appreciate or know which settings would work.

Thanks,
Saur

You should check (confirm) the incoming calls in the 3CX Activity Log to see if the DID numbers sent, match your DID rules. If there is not an exact match, then the calls will route to the default destination. You may want to consider using wildcards (*) for the first few numbers in your rules, to cover variations of the numbers.

Inbound call Routing - How to setup inbound call rules (3cx.com)

And is DIDX a supported provider? Because if so, the template should be preconfigured to know where to look for the DID.

JohnS_3CX · Dec 22, 2020

As per what @leejor mentioned, this is likely a matter of the PBX matching the incoming call, otherwise the trunk's "catch all" destination will be used since none of the Inbound Rules matched first.

These articles can help you better understand how the procedure works so you can manually tweak your settings. Note that as @cobaltit said, this will not be an issue with a 3CX supported provider since we test beforehand and prepare ready made templates that have been confirmed to work as intended.

No, I can't find DIDX in the list for US drop-down under sip trunks. It's strange why it's not supported by 3cx when it's in the market for a long time and has tons of customers.

See attached log, I have replaced the original IP for security reason. Call from DID come to 1001 ext but somehow it doesn't get processed to that ext and always goes to 1000 ext. also see attached settings of the inbound parameter. Please advise.

I see caller ID, but don't see a CalledNum ( the DID), in the le log you posted.

https://www.3cx.com/docs/sip-trunk-inbound-calls/

Are you confirmed with them, that they are sending DID numbers?

tsww · Dec 25, 2020

Does called number is needed because I have set forwarding from DIDX side to
DID1 to [email protected] and DID2 [email protected], and it actually sending it as per log. Why 3cx don't forward call to ext as per its coming.

ivan.antic · Dec 25, 2020

Hi tsww,

Try with changing the following:

1.
SIP Trunks => DIDX (Name of trunk) => General
Main Trunk No: DIDX (Name of trunk)
Destination for calls during office hours: End Call
Destination for calls outside office hours: End Call

2.
SIP Trunks => DIDX (Name of trunk) => DID's
Add DID1 and DID1

3.
Inbound Rules => DID1 Route calls to 1000
Inbound Rules => DID2 Route calls to 1001

Hi Ivan, I have done exactly what you have suggested see the below result in the log. It doesn't work.

tsww,

Based on what is the configuration DIDX that provided could be helpful.

I see on DIDX website that for Asterisk setup they don't require any kind of authentication, you just need to match default context in sip.conf where the inbound calls will land.
Contexts as such don't exist in 3cx.

Try with creating two different trunks against DIDX with each DID you have with them, and then route to 1001 and 1002.

I did try as you suggested, but it's going to ext set in the first trunk. In other words, DID1 and DID2 both land to Ext set in the first trunk.

Finally, It worked now with 2 different trunks and an inbound parameter set with the custom setting as per the attached screenshot. Thanks, everyone, for your help.

I created a separate trunk for each DID, and In the custom field of the inbound parameter for each tunk, I put an extension number for that DID. Also, on DIDX (DID provider) side, I have set a call to land on that same extension that I have set for a particular DID.

I hope this will help someone and will save time for him.
