My Fanvil VoIP phone worked previously on my D-link DIR 825, but after a while it showed sip registered failed. What can be the problem??? As no settings changed on my side.

I made no changes on my side or the VoIP phone

Can it be that the router did an update and becuase of that my sip account does not work???

Sip ALG is turned off.

Please help me out.

sounds like it is the update on the router or a networking/firewall that is causing your issue.

  • If network routing not working from the box: check networking in general
  • SIP provider unreachable - Firewall(s) in the way of the outgoing request or the answer
  • A NAT router with SIP options in the way which happens to block internal SIP on port 5060
  • Try pinging the sip server
