Incomming calls show CallerID and PBX IP Address

[trickyhi]

Incoming calls to my cisco 7941 show both phone number and the ip of the pbx, is there a way to have it only show the CallerID and phone number they are calling from?

Hi trickyhi,

Please explain the call flow.

Is it simply calls coming in via a SIP trunk or the PSTN via a gateway?
Also are these phones local to your 3CX system or down a VPN or something like that?

Hello @trickyhi

Who is your provider and where is the PBX configured to read the calling number from? It sounds to me that your provider is using a different sip field to send the number in than the one that is specified in the PBX.
Do you have other phones that work correctly? If not try a 3CX client for a test and see if you are getting the same behaviour.

This is a local pbx, connect to a sip trunk from twillio. Incoming calls show up as [email protected] on the phone and as +11234567890:default on the 3cx softphone for windows.

The same format is shown for an incoming call from another extension on the pbx

Please make sure that you are using the default 3CX template to add the provider.

Yes I am using the default SIP settings for Twilio

Do you have a QoS for the VoIP? I'd suggest you implement it.

Please navigate to your trunk settings / Inbound parameters and send us a screenshot of the "Caller Number/Name Field Mapping:" settings so we can take a look at the trunk settings.
