Hi I'm using PJSIP on raspberry Pi. It works completely true. But I want to know, do anyone have done this before to make a product. Because it's so important that a successful story exist. Maybe on another platform. If anybody has experience, please share some benchmarks: CPU and RAM usage. It's my results: In an active call with G711 ulaw codec and 8ms tail echo cancelation, on raspberry the CPU usage will be about 75%. And it's so high as my idea. However it should be noticed that I used USB sound card. What other hardware platform do you suggest to work on? Oh, is this possible to use external hardware codec to work with PJSIP, has anybody solution about it? Thanks a lot Farzan -------------- next part -------------- An HTML attachment was scrubbed...
