Can't make outgoing calls on Voxalot

[richard]

Hi

I have a Voxalot account configured for my Dad on a SPA-1001 (line 1) with VoipBuster as a outgoing service provided on Voxalot. It has been configured like this for weeks and has been worked perfectly.

All of a sudden (a few days ago), my Dad can no longer make outgoing calls on line 1 via Voxalot. He can't make calls to PSTN numbers via VoipBuster or calls within the Voxalot network (ie: 500 and 600). Strangely enough he can receive inbound calls via a DIDWW DID which is pointed to his voxalot account.

I am not near my Dad and have not been able to visit him to do any tests, but I can confirm:

1. Its logged into Voxalot
2. He gets dead air when he tries to dial out on line 1
3. His MWI on Voxalot shows a message waiting (shutter tone heard)
4. SPA shows both lines status as "Registered"
4. Line 2, which is directly configured for VoipBuster WORKS FINE!!! (It's on port 5061).

When I get to his house again, I was going to try other ports, ie: 4060, but haven't made it there yet.

Martin or anyone else, any idea what could have suddently gone wrong?

Could it be a change with my ISP?

Could it be something specifically wrong with his Voxalot account?

Any help would be appreciated.

Thanks


Richard
