Voxalot to Voxalot is not working here

[Nakkoush]

Dear Experts,

I have two basic free voxalot accounts registered since more than a year.
I don't know what is recently happening, just like that 4 or 5 days ago I cannot call voxalot to voxalot, or let me say it was hardly working for the last one week (some times I hear voxalot machine cutting my calls and saying to call back later during the call) until today it has stopped completely.

Am I the only one facing this problem?

Thanks in advance.
