Look forward to have VOIP provider to join in. It is fair more easy to add trunk than guessing the parameter and their combination to make them work作者: 角色 時間: 2011-10-22 16:11
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.
There is a major problem on siptosis. Sometimes, your skype clients cannot be shown as online when viewed by other skype users. No reason why. But at the asterisk server, it is online.作者: 雯雯 時間: 2011-11-1 20:47
If network quality improved, cmphone works very well.作者: Maxii 時間: 2011-11-18 20:51
Making my first land line call to Hong Kong today with cmphone trial account on my ATA. Very nice call quality I have experienced. No lagging. Better than on Inum Gateway that I was using. 電訊茶室好介绍。作者: ckleea 時間: 2011-11-18 21:46
