SIP scanners - Receiving calls from name/number 100

[DPMc]

Dear ObiHai,

I can not find the way to make the change as outlined in part 2 of the instructions on the first post in this page. Would you please tell me where to find it on the ObiTalk 100?

2. A more fool-proof method is to enable the parameter: X_EnforceRequestUserID. This parameter is under SPn in the SIP Credentials section.   What this does, is it makes sure the incoming INVITE has a User ID that matches the User ID of your SIP service account. If it does not match, the INVITE will be rejected and the phone will not ring.  Enabling this parameter will maintain normal voice service as well as block SIP scanners. Notes:  Some service providers do not adhere to this rule. This parameter is not available on the OBi100 and OBi110 devices. http://www.obitalk.com/forum/index.php?topic=4067.0
