Hi,

I have set up a 3CX system in my lab with a SIP trunk from 2Talk with 10 numbers attached.

I notice that on outbound calls the pilot number is always presented as the CID, even though I have configured the Caller ID for the extension in 3CX. The call is made successfully.

Can anyone advise if what I want to have happen (show extension DDI as Caller ID) is possible. I know that 2Talk is not a 'supported' provider as far as 3CX is concerned.

My next step is to get a wireshark capture of the outbound SIP initiation, but if someone can tell me whether this can or cannot work I would appreciate it.

I have logged a support ticket with 2Talk but heard nothing so far.....

Cheers

Rod.

Yes it works fine. I have this setup at home for business + home line. I'll check my setup later if I get time and post back.

Thanks to CoffeeBaron for confirming this should work.

I had a look at the outbound SIP mappings and changed

'From : User Part' from ' AuthID Identification' to 'Outbound Caller ID from Extension setting in Management console' (not verbatim cos' I cant cut and paste from the drop down) and all is good.

Cheers

If you are using SIP registration to 2talk you firstly need to go to your registered number and turn on "Outbound Trunking". SIP peering this isn't required.

Then you just need your invites going out like "ddi"@sip.2talk.co.nz and as long as "ddi" is on your 2talk account it will be presented.

is the "outbound trunking" a functionality of 3CX or 2talk?

I guess it is a function of both. It is just a SIP trunk as far as two talk is concerned, and I have set up outbound rules in 3cx to use the trunk. I have defined it as a Generic SIP trunk in 3CX. So far very pleased with the whole setup - about 30 extensions running very well on a Hyper-V 3cx instance running on an Intel NUC.

You enable this particular option in 2talk

Hi All,

Thanks @mod for unlocking this post.

I am trying to do the same and I either get call blocked / forbidden or the pilot number.

Of the 3CX installs I have done, none have had DDI's.

Getting the DDI to work was easy enough but I cant get the outbound CLID to present the DDI

In 2Talk - Pilot Number ==> Outbound trunking ==> enable outbound trunking on this line is enabled.

2talk - DDI ==> Caller ID and Privacy. Present a number from your account / account number selection = DDI

3CX

Extn: Optionally assign a DID to receive calls directly to this extension has the DDI number.

If I call that number from home my extension rings, but if I ring home I get the pilot number.

3CX

extn: A bit further up there is a field called Outbound caller ID ( Below mobile number ). If I leave this blank I can make a call.

If I populate this with my DDI my phone says forbidden.

If I go to the 3CX logs

SIP Server/Call Manager ID: 12294

Call or Registration to Home Number@(Ln.10001@2Talk Pilot Number) has failed. 27.111.14.xx replied: 403 Forbidden; from IP:27.111.14.xx:5060

I can receive calls however

If I remove the field called Outbound caller ID ( Below mobile number ) I can make a call straight away.

We are using a lightsail 3CX 16.0.14.504 ( Professional )

Our 2Talk is a SIP registration with std 3CX settings ( Auto discover for want of a better term )

If I could please use the wisdom of the crowd to get this working i would appreciate it.

Cheers & stay safe everyone.

regards

John

On the SIP Trunk you have setup have you added the numbers that you want to be presented as the caller IDs?

SIP Trunks - Select your SIP trunk - DID's - add single DID

Hope that helps...

Thanks for the reply.

Sadly, yes, that has been done already.

Are you using the certified 2talk trunk config in 3CX? The one that the wizard sets up?

Should be SIP peering and it will set up the invite format for you.

Then once SIP peering is enabled on 2talk and pointed to your 3CX install, it will take whatever is sent either the From user or P-asserted ID.

I got it going - Yay, but will do more testing.

In the SIP trunks ==> 2talk sip trunk ==> Outbound parameters From:DisplayName "OutboundCallerID" Outbound Caller ID taken from Extn

to From:DisplayName "AuthID" Authentication.

Same for From:User Part "OutboundCallerID" Outbound Caller ID taken from Extn

to From:User Part "AuthID" Authentication.

Thanks for everyones help.

Yes this is the certified 3Cx config, basically I just entered the phone number and password and the wizard did the rest.

At closer inspection is must be peering as the

Registrar/Server/Gateway Hostname or IP is peering.2talk.co.nz

Thank you so much for your help.
