SPA942 Register Failed

i have asterisk up running for some time now and now i have decided to bring in SPA942 phones to replace planet phones which seems to have some problem working with asterisk.

however after configuring my first SPA942, i realised that it failed to register with the server. i have checked the logs files and nothing seem to tell or indicates where the fault lies.

i have followed the configuration guide that came with the phones but still i get the register failed message

i am using freepbx

would appreciate if anyone can direct me to where i can find a solution or any suggestions to fix this


I am using 941’s, same phone basically. Let me know if you are still having problems and I’ll see if I can help you out.

  1. Try getting support from the trixbos forums (
  2. Is the phone and the same subnet or are there any routers in between ?
  3. Anything set in IP tables ?
  4. What comes up in the CLI ? Anything ?
  5. Try the asterisk users list @
