This list has been running long enough long enough (more than 3 years now) and I've heard many discussions about embedded use of pjsip. About CPU requirement, I know for sure people who have production hardware running pjsip on a 20 MHz MIPS (can't name them for political reason unfortunately). And don't forget about mobile devices as well, which from device capability is not dissimilar from embedded. So I don't see any problems with this. It's just a matter of configuring it correctly, and of course we all know this is never straightforward with any embedded developments. > personally have faced some problems regarding the performance in an > application using ARM9 and may be forced to abandon the use of PJSIP > in my project. > What is your expectation anyway? If you expect to run 8 simulteneous speex calls on your 200MHz ARM9 then probably it will never happen. And as I told you, siprtp is thread based so this probably is not the ideal approach for your development. And why are you using siprtp to measure up pjsip. What are you trying to do in the first place? I'm just saying that there are plenty of options with pjsip. There are plenty of features. And each features come with their own cost (CPU, memory) of course. So it's always a matter of choosing the right feature to have, to fit in the capability of the device. And you haven't explained what you're trying to do, so we can't give good suggestions for now. Of course nobody forces anybody to use pjsip. There are plenty of other choices. It's just a pity if you have to abandon pjsip based on wrong experimentation. Cheers Benny
