Lync 2013 Call Forwarding Caller ID

Michael Esteves 1 Reputation point


We do have a site in France where we enabled forwarding calls for 5 user accounts to their technical team who works externally. Customers call the phone numbers of these 5 user accounts to ask for help technically.

Here is the scenario:

Customer phone#: 1234
User phone#: 8127
External phone#: 1500

When the external team receives the call, they do not see the correct phone number but what they see is totally different one.

I tried replicating the issue and assigned myself a phone number based in France. I used Sefautil to forward the calls immediately to my mobile phone number and when we tested it, the phone number displayed on my mobile phone is the main hotline which is 8100.

I am not sure if this is normal behavior or is there a way to manipulate the caller ID to show the customer's phone number to external contacts?

I am looking forward to your responses!

    I just would like to add that we use Audiocodes as our SBC. Is there a way to manipulate this caller ID via its GUI?

    Hi @Michael Esteves ,

    Do you mean the customer phone number display is different from their assigned phone number? For
    example, Customer has assigned “1234” but it displayed “1500” from the technical team view.

    If you want to modify the outbound caller ID to display main inbound phone number, you need to remove the line uri for the user. If they are fake numbers then they don't work anyway for inbound calling. You don't require a line uri in OCS for Enterprise Voice enabled users to make outbound calls.

    If I misunderstand your requirements, please figure it out! Thanks for your understanding!
