Over here it's GSM. nothing more nothing less. Yes, it's noticable, but it's not terrible and it is consistent. I'm not aware of the networks imposing more compression on top of what the handset itself does. > They compress the audio so much it's rather > obvious.

I'm getting the impression that the telcos in the US are basically shafting you because of the monopoly they have. More intersted in keeping themselves happy than their customers. I think it's nice I have a choice of 5 major mobile phone carriers in the UK, and well over 100 ISPs for broadband via the BT Wholesale network. > A fun test is to call a landline from your cell in the same room and > note now long the delay is.

There is a delay - but I've never really noticed it unless I play tricks on the network like that. It's certianly nothing like making a call to Austrailia! > None of the carriers really offer a phone that can do SIP, as far as I've > seen. As soon as the iPhone software 2.0 is out, there will be one for that. Don't rely on the carriers to provide you anything - there are plenty of phones on the market which do SIP now - most modern Nokias do. I use an E90 Communicator, but the E95 is popular too, so I'm experimenting with using my mobile as my "one" phone, via Wi-Fi/SIP when I'm in the home/office and GSM/3G when out and about. It's not perfect yet, but getting there. (And 10:1 gives you a SIP service on the iPhone that's locked into their own service ;-) Cheers, Gordon _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
