Hi All, I wonder if anyone has used the PJSIP in an embedded environment, with low requirements of memory and processing power (something around 200Mhz). For what I have seen the stack is behaving well in desktop, but I have not seen much discussion on embedded environments. I 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. All opinions are welcome. Thanks in advance.
