Re: [Serusers] NAT ping and consumer router

This depends on wether you have control or not. As a service provider we have to deal with hundreds of different NATs/Routers all over the world. We do not have the luxury of demanding users to buy a certain NAT device (and some NATs are even embedded in the modem provided by their ISPs). On the other hand we do suggest our users get one of our "supported" UAs which have been heavily tested by us. That being said, our number #1 issue right now are broken SIP Aware NATs all over the world. We are constatly having to move these users to other ports besides 5060. I wish NAT vendors would give up on this idea. We prefer to solve this by a combination of STUN/RTPProxy which has worked flawlessly for us. I agree...please stop this futile attempt! (I can understand a handful of vendors are smart enough to get this right, but for sure it is impossible for most to do it) -- Andres Network Admin http://www.telesip.net
