For security sake, please uncheck "Allow guest calls".

可能真是跟你們的Router proxy 設定有關。有沒有在GUI 設定outbound proxy?

When make outgoing call, it reply with 503 Services Unavailable. But it was funny that there is no problem if I use Linksys RTP300. Can make call sucessfully.


Workaround is to use a Linksys router with a customized image to make a transparent proxy. This route all requests to allow outbound proxy requests to be possible.

角色兄何以不試試你的 IP01 呢? 我用你提供的號碼是可以在 IP01 使用跟你通話。你可以從那裡開始去尋找問題癥結所在。

我Network 要同時行兩個Asterisk 的時候，我一定會很清晰地分開兩個 Port 5060 及另一個是 50XX，但我想有很多時候一些版友會一時間忘記此重點的。Incoming call 沒法派送到不知名地址(位址)，就會馬上被 drop 掉的。

If qualify is set to "yes" then, by the looks of it, Asterisk will use the information about round trip time to decide whether or not to bother registering. If the SIP OPTIONS packet doesn't receive a response, it assumes the server is unreachable and probably doesn't bother trying to register. Switching off "qualify" is obviously necessary with such providers.

It's also generally a good idea to have qualify=no for softphones and maybe some hardphones. the OPTIONS packets can cause problems with them.

Purpose of qualify=yes
On the other hand, one of the main benefits of qualify=yes is to detect network problems with peers.

We send a lot of calls via a service provider using SIP but we have qualify-yes set so that if it becomes unreachable the dial fails
immediatly without having to wait for a timeout which enables us to
seamlessly failover to an ISDN or other connection.
