Here are a couple of thoughts... If these don't work, can you send a screenshot of the Phone & VG Phone, and the Extension Configuration on each of the devices?
- Are the extensions showing as a "shared line", so we can verify that they are built in the same partition? What partition are they built in?
- What partition and calling search space are you making the test call from?
- If you remove the number from the 7912 does the analog phone ring when you call it?
Thanks,
