VIC-4FXS/DID and VIC2-4FXO Caller-ID Support

Unanswered Question
Mar 12th, 2010

Hello everyone,

I am just wondering whether or not the VIC-4FXS/DID and VIC2-4FXO support the display of both name and number caller-ID.

Thanks in advance!

I have this problem too.

  I see that Caller ID is supported and I am assuming it is a given that both name and number are supported?  Just want to verify before moving further with a project.

Thank you sir,

VIC-4FXS/DID cannot receive caller ID.

It is made to either connect analog phone or other device, or for analog DID service, that is kind of rare.

Consequently, it can generate, but never receive called ID:

They both support it, in different ways:

FXS = send caller ID

FXO = receive caller ID

One connects to the other... if you have FXS, then you need to send caller ID if you have a handset or other devices that wants to receive it.

When you receive caller-ID on an FXO, it could come from an FXS at the far end.

I don't recall seeing anything differentiating between support for name and number anywhere, so would presume (and then test) that both come together..

  So if I am running a setup on a 1760 running CME with a VIC2-4FXO and two VIC-4FXS/DIDs with a total of eight internal lines and three external lines coming from the phone company, the internal phones connected to the VIC-4FXS/DIDs will not recieve caller ID information from outside calls?

Theoretically at least, they should... see the diagram part way down this page:

Your flow in this case is User D to User A.


"A receives the calling number and name of D, provided that the PSTN subscriber line (408 555-1111) is enabled for Caller ID."

You'll note there are a few methods of picking up and sending out the caller-id = for example in the UK we have to use an obscure method (caller-id alerting dsp-pre-allocate, a hidden command last time I did this) to get it to work. No doubt if you are in the US life will be easier...

Please note that you will have poor results using a 1760, because it's an old discontinued model that does not support current IOS.

You should use an UC520 for this, as it als suppoer directly the IP phones thta are to preferred over analog instruments.

The setup is for a small restaurant business running eight extensions and analog phones.  Do you believe the performance will be very poor?

I do think so.

For example without "FXS SCCP Mode" there is no easy way to transfer a call, hold or just a speakerphone paging.

Also have you tought about voice mail? They may get business calls when they are closed.

These things are invariably requested.

I have a single 1760 installation (ebay bargain) and does the job, but they have all IP phones and the situation is very different than basic analog.


Did you have any luck with this?  I know you'll have no problems getting both incoming Calling Party Number/Name on the FXO card, but I'm quite certain you'll never get Name from the telco trunk on analog DID card.  As for Calling Number, I think (in theory) it should be attainable from the telco on the analog DID trunk, though I'd like to know if the 3rd Gen VIC3-2FXS-E/DID card will deliver it.
