回復 25# lamsoft
多謝lamsoft 兄的測試分享。看來cmphone 能夠於Asterisk 打出打入的問題解決後,一定會有很多朋友申請使用了。
說起SipToSis 大量耗用電腦資源一事,我也略有所聞,翻查之下,在官網有以下一段敍述引證lamsoft 兄的說法。
How many concurrent active Skype calls/channels can I make using this SIP Skype gateway with a PBX such as Asterisk? You are limited by your available resources (memory, bandwidth and cpu). Here's the approximate per channel memory consumption and cpu usage for both supported multi channel platforms.
Windows - 56-70mb - Approx 12% cpu with an AMD Athlon 2700
Linux - 52mb+ for SipToSis & Skype and 16mb+ for Xvfb - Approx 5% cpu with an AMD Athlon 2700 using snd-dummy. If you use a different method to create X sessions, your memory usage will be different.
Conservative Ram Calculation: (#channels x 100MB) + OS ram requirements MB + Other APP requirements MB = TotalRam MB
CPU usage above is with standard PCMU codec (30ms packets) and RFC2833 DTMF. You will have to experiment to find the limit for your environment. You can always expand your channel count by adding more boxes. There are no built-in limits. Use of a broadband internet service provider with sufficient bandwidth is required for multi channel operation.
I have run 10 channels myself - I do not have enough bandwith to run more. Some have run 40 channels. If you run 40+ channels I recommend a dedicated 64 bit quad core server with 8gb ram running linux.
好在我暫時只是使用一條Single Channel 作測試/備用,影響不大。始終Skype可到之處,實在很廣泛和方便,有時真的很難抗拒使用。 |
