I'm trying to get external validity by checking if people with different setups than mine can reproduce the issue.
Assuming they are blocking it, it's interesting that they're allowing the handshake to take place, but not the actual voice data.

Update: I just talked to Nuclearcat (who works at VISP), it seems that Ogero has indeed blocked SkypeOut. This means all (legal) ISPs are affected. It seems that deep packet inspection is being used. Any further technical info about the filtering would be appreciated.

But I don't get it, why blocking skype and not all VoIP services ? I am making calls over the Internet everyday, service has never been better.
Buy a VPN account with a dedicated ip ?
www.nvpn.net is a good and cheap one.
The point was to investigate whether it were being intentionally being filtered by Ogero or if it is a misconfiguration issue.

Eliminating 80% by doing 20% of the work.
I have a skype phone and I am experiencing exactly what you're facing with skypeOut. (TerraNet) Is there any workaround possible ?
same here. I have Skype on my phone and I use it all the time to make calls to landline and mobile numbers and lately I have been experiencing the same, cant hear the other person and vice versa.
Yes indeed they blocked skype out and all the other VOIP.
If you use windows Hotspot shield is your new friend for VOIP
I mean a "Skype Phone" as in literally a cordless home phone that has skype on it. Any solution for my case or am I obliged to use some vpn and call only over pc? The skype phone connects to the internet through lan, is it possible to connect my pc to a vpn and output a lan cord to the skype phone by maybe adding another lan card to my pc?
I would say either use your PC as a server for your phone connected to a vpn or configure a vpn on your router (No idea if it's possible).

Though try searching for the answer online, Im sure other people have also had the same issue.
Leonedes, as long as you are calling someone who is also using Skype, you don't need a VPN because those calls are not being filtered.
I am strictly talking about SkypeOut ... I use the skype phone to call relatives on their home phones abroad.

I just figured out how to use Skype on 3G. I created a free VPN account and set it up on my mobile! I can call numbers and the other party can hear me but of course I still can't receive Skype calls forwarded to my mobile number. I will have to have Skype app open all the time so to not miss any call.
I have been facing this problem in the past months, i have tried with multiple ISP's (OGERO, Moscanet, and Lynx), it's the same.

Seems OGERO Blocked it.

What about Signing a Petition and presenting it to the Minister of Telecommunications?
Badga - he will send to you petition then, how you can help him pay country financial debt :)
This may be off topic but Google's pc to phone service is not affected as I use it daily. Their rates are pretty good and call quality is superb, for those of you looking for an alternative

The country's financial debt was not my fault. They now discovered Gas. Let them use the Gas money to pay off the Debt instead of filling their pockets.

If we do not take action, then Ogero will gradually block all VoIP. Yesterday, it was Skype Out, today it's LocalPhone, tomorrow it'll be something else.

"offtopic" IF they Begin extracting gas.. we will not get a cent from it .they will keep filling their pockets cz no one will stop them "/offtopic"
I heard somewhere that it's blocked but I can't really confirm that.
