I'm having difficulty with this feature. I have a Linksys SPA 3102, with both ports registered with my SIP provider. I've enabled PSTN-To-VOIP. I would like to achieve the following.
1. If I call my PSTN number from my mobile, I should be given access to the VOIP.
2. All other telephone numbers should not have access to the VOIP.
My understanding is that this can be configured with the PSTN Caller ID Pattern. However, when I put my mobile number in the field, the PSTN to VOIP gateway cease to function for all numbers. I've confirmed that the CLI is working as I can see my mobile number on the info page.
Has anybody solved this problem?
