[Frage] Verify DID/VoIP // why is my DID/VoIP-in gone?

[Agile]

Dear Forum,
I have an account with SipDiscount (aka Betamax group) and I got a DID/VoIP-in when I created the account a few years ago (a +31 85... number).
I have not very actively used it during the last period. Recently I topped it up again and found the DID/VoIP-in does not work anymore.

However, if install "MobileVoIP" on a smartphone, it reports that there is a VoIP-in number; the one I previously 'owned'. I verified on another Smartphone to ensure the MobileVoIP app gets the VoIP-in number from somewhere outside the phone. From the app I can actually use it as caller-ID (this is probably not relevant).

So, if MobileVoIP can retrieve the DID/VoIP-in from somewhere, I figured there could perhaps be a way to reactivate it.

Question:
- Can I check the 'status' of this VoIP-in number on some website or using some tool?
- Would there be a way to reactivate it with my SipDiscount account?

Tnx, Agile.

Dear Forum,

I understand that the VoIP-in/DID number is still "Active" (information from SIPdiscount helpdesk)
So, what I need to do is forward the number [again] to <username>@sip.sipdiscount.com.

Is there a way retrieve where my VoIP-in/DID number is registered?
