I found your message on one of the threads I’ve created.
[quote]One bug you should be aware of-
In the AAstra phone setup (config files or web ui), there are two NAT options. There is SIP NAT IP (or something like that, feed it your external IP) and SIP NAT PORT. SIP NAT PORT does not change the local SIP port of the phone as it should, rather only changes the contact header of the phone to refer to a different port (and packets are still sent from and must be recieved to port 5060). I have contacted AAstra about this, the support guy I talked to agrees it’s a bug but the engineering department disagrees, its not a bug its a feature Smile
so if you are putting multiple AAstra phones behind a NAT registering to a remote * server, this will probably nto work reliably.
To make one phone work tho, forward udp port 5060 and an RTP port (you can set it up in the aastra setup, that one configures itself correctly) to the aastra phone. Now set the phone to register to your office LAN IP, which should have port 5060 and the rtp range from *'s rtp.conf forwarded to it.[/quote]
So what you are saying is that I cannot use use multiple Aastra phones. (That’s what I wanted to do…) do you have any more recommendation on phones that I can use instead that will do the job?.
