I would go to the OBiTalk Dashboard. to the right of the name that you gave
to your OBi, do you have a green icon under Status, which indicates
Online? Click on the name that you gave to your Obi. Under
Configure Voice Service Providers (SP) does it say Connected or Registered
for the service provider that you are having the problem with?
To test for router problems if you have a separate router, consider
connecting the OBi directly to your modem without the router as a test.
Do your symptoms change?
Regarding "touter = router", there is a Modify that you can click on to modify a post. There is also a Remove.
