Why not?
VoIP phones normally connect directly to each other, with the VoIP exchange used to advise the phones of the other phone's IP address, using H.225 (Registration, Admission and Status or RAS) to pass the info between phone and VoIP exchange and also between exchanges. If you don't use real world IP addresses to the phones, you'll have to use a gateway at each carrier, convert the call so some other network to get to the next carrier to reach the destination. RFC1918 addresses could work, but only within one carrier's network.
They are likely going to replace current smartphones, all of which have IPs now.
Right now, there are still a lot more 2G phones around and people are still buying them. These are the old GSM or CDMA phones that have been in use for years.
They are all behind nat too.
Yes, I was already aware of that.
Visitwww.whatsmyip.net on your nexus one. Then dial *#*#4636#*#* and select Phone Information. Scroll down till you see Interface Rmnet0, compare numbers.
4G phones is a meaningless term. LTE is meaningful, but does not require ipV6.
LTE is the progression towards full 4G. And no, they do not "need" IPv6. What they do need is sufficient IP addresses to support them all. IPv4 is near exhaustion. Using RFC1918 addresses and NAT will get in the way of setting up a proper VoIP network. Here's a link to a Wikipedia article on 4G: http://en.wikipedia.org/wiki/4G That article includes the following: "Unlike 3G, which is based on two parallel infrastructures consisting of circuit switched and packet switched network nodes respectively, 4G will be based on packet switching only. This will require low-latency data transmission. By the time that 4G is deployed, the process of IPv4 address exhaustion is expected to be in its final stages. Therefore, in the context of 4G, IPv6 support is essential in order to support a large number of wireless-enabled devices." http://en.wikipedia.org/wiki/4G -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
