Last time I had problem in connecting with my Intel ATOM-based Asterisk server. I do not know whether the problem came from the setting for type, which I mistyped as typp. I will check it on Monday morning to see any improvement if I changed it to type.
问题: 用SPA IP Phone注册可以(例如ext 2001),但是在Asterisk Server看到ext 2001 unreachable
解答:
1) 我的第二台Asterisk server B全用default port 5060,而我利用我的router,做port redirection,从5228 UDP Port转到5060 UDP Port of Asterisk server B IP,于是我可以注册到。
2)但是这个“转动”改动是单向,而不是双向, 所以Asterisk server B能注册,在Asterisk server B想发出UDP packets to IP Phone时,因为router不会把Asterisk server B IP:5060, 往外面转至WAN (IP) Port:5228。
3)在更改Asterisk server B的bindport=5228,和router,用port forwarding,WAN的5228,转到Asterisk server IP的5228,就可以。这个转向是双向的。
Now I have two servers running at the same time,one is QNAP TS-119 NAS Asterisk and the other is Intel ATOM-based D515 Asterisk. I may add another one IP-01 later. If I have time, I may add one more for testing purpose.
