| We already have TCP support for iOS of course. Sure. I mentioned iOS, because PJSIP seems to support IPv6 over UDP for a while now, implicitly declaring TCP the "not so important" protocol in a certain way. I just wanted to say that TCP is not "not so important" on iOS. ;) | So the question is, is | there really a situation with iOS where *IPv6* TCP is "the only" | option? Because we were talking about #1127. No. Of course TCP/IPv4 is working fine on iOS for a long time. But there are situations, where you *want* IPv6. As far as I have seen it, iOS prefers the IPv6 address over the IPv4 one, when resolving a hostname. So if you are doing address resolution using the system APIs, you need to handle that. Actually it's no big deal, because IPv4 will still be around for a while and filtering the list for IPv4 addresses is easy. It just doesn't feel right, to bypass IPv6 if it is available on the network. ;) Keep up the good work, Sebastian.
