1. 兩個SERVER原來都可以無需使用不同的SIP port，即是同一樣用 Port 5060 即可，IAX Port 也可以同時用 4569，條件是兩個Realm 要不同， rtp ports 要不同，打出打入沒有問題，Router 可以正確辨識。
2. 至於用有線IP Phone (我用Cisco Linksys SPA942) 、Siemens S685 無線 IP Phone 的接駁SERVER時間，就有很大的分別了。 在CLI 用 sip show peers看，分別如下:
SPA942 7ms
S685 74ms
Server <-----> Server 1ms
連接香港另一網友的SERVER 25ms
從以上發現，S685 不知發生什麼原因，竟然比較有線的IP Phone SPA942 用超過十倍時間登陸。而比較遠端網友的 REMOTE SERVER 所需的 25ms 還要慢兩倍，雖然不會影響話音，但大家知道這是正常嗎?
最理想是 SERVER to SERVER 之間的連線， 1 ms 真係快過霎眼。 作者: ckleea 時間: 2010-10-16 20:25
My Siemens IP phone is 103ms.
SPA3000 11ms
網友的SERVER 25ms
IP01 (same LAN) 2ms
skype trunk 2 - 4 ms作者: ckleea 時間: 2010-10-16 20:37

Sometimes, the Siemens phone is even worse with 273 ms
Also very often has this error in the asterisk log
Oh! I am not the only one that face this situation and luckily, not the worse one
We might conclude that the delay come from the communication between the handsets and the main unit which is passing signal in wireless mode.
As I have purposely enabled the Economic Mode to the main unit to weaken the transmission power for 50% or more , I will try to disable it to see if there is any improvement.作者: bubblestar 時間: 2010-10-16 22:35
Just tried to disable the Eco mode in the Siemens main unit but it seems this measure has nothing to do with the accelearation to connect S685 with my Asterisk Server. The result remains the same at 74 ms.作者: ckleea 時間: 2010-10-19 15:16
Consistently Siemens IP phone reading is about 72 to 77 ms.作者: ckleea 時間: 2010-10-19 18:23
Bubblestar 兄, 請問每個 asterisk server 用rtp port ranges 要幾多，如server handles max 20 concurrent calls.作者: 角色 時間: 2010-10-19 20:12
