Sip trunk - Incoming calls fail

[rodri332]

Dear,
I have installed in a IP Office 500 Release 9.0 with a SIP trunk like with 50 channels. It has to be registered with an username and a password.
The service's supplier asks as a requirement to the outgoing calls that the "From" field of the SIP URI sends the ID's username.

Settings for the outgoing calls:
SIP LINE --> SIP URI --> LOCAL URI: Use Credential Authentication Name
SIP LINE --> SIP URI --> REGISTRATION: 1: Credential Authentication Name

With this settings the outgoing calls are out with no problem.

The problem is in the incoming calls. When an incoming calls enters from the trunk line SIP in the traces, the screen shows the error 404 Not Found. The supplier sends the caller ID (12345678).

Settings for incoming calls:
USER --> SIP --> SIP NAME: 12345678
USER --> SIP --> SIP DISPLAY NAME: PRUEBA
USER --> SIP --> SIP CONTACT: 12345678
ICR --> STANDAR --> LINE GROUP ID: 17
ICR --> STANDAR --> INCOMING NUMBER: 12345678
ICR --> DESTINATION: 5678 (PRUEBA)

Could somebody help me with this problem that I've got?

Thank you very much for your help

Thanks for your help. I've configured these options but doesn´t work.

Could you possibly give me some other advice to solve this problema?

For the settings in SIP LINE --> SIP URI --> try with "Use Internal Data"
