We sometimes get that we cannot get through when dailing our number: 0872382607 even though no one is on a call.
It says that “ the subscriber you have dailed is not available at present. Please try again later”
I hope you are well. I see your extension is currently offline on my side. The call is failing due to the fact that the system sees your extension as offline so it will not push the call through. Please register the account and test again.
