voip via cellphones

Postby 36510 » Thu Dec 03, 2015 9:09 am

Is the use of mobile voip generally permitted in Cyprus or will it be suppressed by certain providers / for certain plans?

If I've understood you correctly your mobile provider will not even know you'll be using your phone for voip calls. I have Sip Softphone on my iPhone which allows me to use my offices voip service. Our office uses voipfone.co.uk and I highly recommend them. We were paying anything between £800 - £1200 per month to BT. That cost is now down to £50- £100 per month.

Good luck with your connection.

There must be a way for them to pick that up because in Germany (where I'm from) some companies are marring voip calls on certain plans. That's why I'm asking.

I am no expert on the subject but I'm scratching my head wondering how they would detect an app on a smartphone being used for voip calls.

Blunt way - dont detect anything just block common voip ports (5060 for example). More sophisticated is to have deep packet inspection systems running on their routers. This basically allows them to determine what 'kind' of packet is passing and treat different types of traffic differently. There is no doubt some 3/4 G mobile internet providers have sought to limit the eroding of their voice call revenues by undermining voip on their data services. That is (one reason of many) why net neutrality matters.

I guess that makes sense. My cousin in Kyerina has voip in his hotel and uses the same app I use with no problems. I'd like to think the OP would not have any problems doing this in the ROC.

I'm not sure if this helps but I always travel to Cyprus through Larnaca and always roam to a ROC mobile network and almost always talk to my office through voip simply by dialling an extension number and then always call mum to tell her we are here safe and sound (she is in a state of panic until she hears from me whenever, wherever I travel :shock: ) Does this help OP's question?

To be honest it's adding another layer of confusion. What do you mean when you say you "talk to your office through voip simply by dialing an extension number"?
When using skype from my cell I simply open the skype-app and make a call (decent internet connection provided) by either dialing the number or choosing the contact. I don't understand what you mean by dialing an extension number.

Sorry if I've confused you. When I open my Sip Softphone app it behaves as though I'm physically in my office. We have 7 extensions (200-207) I simply dial one of the extensions, ie 205 to talk. To talk to my mother I dial the whole number including the international code and that call costs me 1p.

I'm of the belief that since I'm using a Cypriot service provider if there were restrictions I would not be able to do this. Check out the Sip Softphone app on line. It's really impressive and never fails.

Know what? I'm not sure if I actually need to add the international code, can't remember. Old age catching up at a rapid speed :(
