Incoming calls forwarding to voicemail

Post by beket7 »

Was working fine during 2 years, and suddenly incoming calls forwarding to voicemail with no rings. Outgoing calls with no issue.
When you call, says:"customer is unavailable, leave your message"
How to fix?

There are a few causes for this problem.

As always, make sure your device is configured according to the official guidelines at http://forum.fongo.com/viewforum.php?f=15 . In particular, your registration interval should be set to 3600.

If your equipment is already configured properly, try the following steps in order and let us know which one (if any) solves the problem.

1) Be sure that Call Forwarding or DND is not accidentally enabled.
2) Change your SIP Port / Local SIP port / X_UserAgentPort to a random number between 20000 and 65535.
3) Change your SIP Server or Proxy from voip.freephoneline.ca to voip2.freephoneline.ca or vice versa.

If that does not help, please answer the following questions so that we can offer more specific advice:

4) What ATA are you using? Does it report that it is registered, and if not, what does it say?
5) What router are you using?
6) Who is your ISP?

Good luck and merry Christmas,
