A phone number that has been in use since last year has begun to refuse to register with freespeech.
I have tried different methods/applications but all have the same result - failure to register - most of the time.

Any suggestions?

Thanks.

contact the help desk

I didn't find a "help desk" but I did log in to my account which I had not done for quite a long time, and the number seems to be registering OK since.

Maybe I need to log in to the account every so often?

Seems OK now.

Thanks.

I forgot to post back here ....... the problem was that my ATA was set to retain the registration for a long time.
If I had problems and rebooted my router several times then the max amount of registrations was reached until one of them timed out ---- a long time as I said.

Changed the registration time on the ATA and all is well.
