I am configuring a 3CX using a Flowroute SIP Trunk and a Canadian DID. When I call out to my cell phone, the incoming call on the cell handset only reports "Unavailable" as the Caller ID.

I have CNAM sets created and approved in Flowroute but can't attach them to the DID (I'm assuming because the DID is not a US number), Attempting to "Set CNAM Storage Preset" results in a "None of the DIDs that you selected are eligible for CNAM storage service. Please change your selection and try again..."

Within the 3CX, the "Outbound Caller ID" for my extension is set. Within the "SIP Trunk"-->Outbound Parameters, I've set the:
  1. "From: Display Name" to: "'Caller Name' caller's name (default: From->display name)" (because the default wasn't populating the field either),
  2. "Remote Party ID - Calling Party : Display Name" to "'Caller Name' caller's name (default: From->display name)"
  3. "P-Asserted Identity" to "Custom Field" with value "Daryle N##########" (my name as a test--I'd like it to be dynamic.).
I am not able to get any value for an outgoing caller id showing up and very interested in suggestions.

Thanks.
 
Hello @Daryle

Since you cannot assign your outbound caller ID number to a name then i would not think this would work as Flowroute uses the Cnam service to identify and pass on the caller ID.
This is something that you will need to sort out with Flowroute.
Also i would recommend reverting the changes you did on the outbound parameters as this could affect outbound calling.
If you wish to send the number i would suggest changing the From: Display Name to Originator caller ID
 
Thanks again Yiannish. I've opened a ticket with Flowroute and share their findings back here for others.
 
Let us know how it goes as i am sure other users will find this helpful
 
So in talking with Flowroute, they agree that because I am configuring Canadian phone numbers, CNAMs will not work:

"CNAM is not supported for Canadian DIDs.

If you at least put your number as caller ID, receivers will see the number show up. You can try setting p-asserted-identity in this format,

“Your Name Here” <sip:1xxxxxxxxxx@x.×.×.x:5060>

to try to force value to pass, but it’s not a guarantee – mostly will get dropped."​

In following up, I asked where to configure this. The 3CX-->Sip Trunks-->Outbound Parameters-->"P-Asserted Identity:Display Name" field can't store this many characters with a full IP#.

Flowroute responded,

"This field should be auto-filled by PBX. _@x.×.×.x:506 _, not manually entered.

You might check with the PBX support for information on correctly entering values in this field."​

I couldn't find any explanation of how to manage these parameters on the 3CX sites.

All that comes across to the receiver's phone is "Unavailable" (see screen capture).

Any ideas of what Outbound parameters should be set to what?

Hello @Daryle

Thank you for the update on this. As Flowroute mentioned even if you configure the value in P-Asserted - Identity it will most probably fail
You can try however and see if it works for you as Flowroute suggested. To do so make a note of the settings before changing anything and then set the P-Asserted-Identity like the following screenshot.

In the custom value filed fill in your name and see if that works. If not revert back to the original settings so at least the number is shown.

US systems do not support the same system as Canadian carriers. American phone providers use a CNAM lookup which is not available for Canadian DIDs through Flowroute. Canadian carriers use a text string as part of the Caller ID value which American carriers do not support. I suspect that routing of the call through US gateways strips off the text string before it reaches the call recipient's Canadian carrier.

As a result, the best I can do with Flowroute as a provider is pass the caller ID number on outbound calls.

Within 3CX, set the following Sip Trunk--> Outbound Parameter values to:
P-Asserted Identity: Display Name --> Custom Field --> Atlas Solutions
P-Asserted Identity: User Part --> "OutboundLineId" Outbound Line Caller ID taken from Outbound caller ID setting in management console
P-Asserted Identity: Host Part --> "GWHostPort" gateway/provider host/port

Set SIP Trunk --> Caller ID to 1##########, the subscribed Canadian DID.

Set Outbound Caller ID in the 3CX Extensions menu for all extensions to ########## (the Canadian DID without the initial 1.
