Office Number


Recommended Posts



we use the feature DISA to dialin in the pbx and to make outbound calls via the mobile.

We have clipnoscreen on by the provider so the number from the caller is to show by a redirection of the extension to the mobile.


Outbound calls via the mobile to show the mobile number and not the office number, our customer want to send the office number.

Our idea is to handle this via the dialplan and to change / replace the mobile number to the office number without sucess.


We must set the P-Preferred-Identity to the office number how can we do this in the dialplan or any setup idea for this.

There is a setting in the domain for that, did you try to flip the switch yet? Regarding the SIP headers, there are a lot of variables at https://vodia.com/doc/trunk_custom_headers that you can use to present what you need to present to your provider. You can use the if tags with disa, so to make conditional content in the headers. It might be a little bit of tinkering, but you should be able to get that working properly.
