Hi

I live in Cyprus and have broadband with satellite.

Using Skype is not very good. There is latency

I have spoken to our service provider and enquired about using Tesco
Internet Phone. He says if I find out what ports Tesco Internet uses he will
prioritise the ports.

Does anyone know which ones it uses?

Are these the same ports as used by other SIP phones?

Many thanks

It's not looking likely -

Eh? Works perfectly well on cable.

I can imagine "Tesco Internet" not working, or some form of CPS or Indirect
Access for call charges not working. However, the OP was asking about Tesco
Internet Phone.

So, in answer to the OP's question, I'm sure that their service is IAX
based. The standard port for IAX2 is 4569

The Tesco service uses the IAX protocol which does both signalling and
audio on a single UDP port, 4569.

No. SIP uses multiple ports. 5060 (generally) for signalling and a range
of other ports, which can be specified by some clients, for audio.

A search with 'IAX' and 'Tesco' will pick up previous posts of interest
to you made in this newsgroup.

If your broadband is via satellite, your always going to have at least
~ 240 mS of latency due to the distance of the satellite from the
earth, regardless of using Skype, Tesco or anybody.

You are thinking of Tesco Home Phone which is a CPS service over a BT
line.. the OP was enquiring about Tesco *Internet* Phone which is an
entirely different service.

Wouldn't the ground station to satellite distance be 35,786km?

Assuming a geostationary orbit and a receiver on the equator at sea
level?

Wouldn't we get latency when Internet traffic is routed normally through
satellites and packets get re-routed? I mean, a call from the UK to
Australia is a) very far & b) probably going to pass through a satellite
somewhere so VOIP shouldn't work at all.

Thanks guys, much appreciated.

Bearing in mind the points raised would people suggest the Tesco system one
perhaps one of the other service providers?

Thanks
