Hi, The current version of pjsip, will work for 32 calls at a time, Assumed every call supports only audio. Bcz ioqueue instance can only handle 64 handlers. Could any one suggest me is there anyway to increase this limit. Thanks for all valuable suggestions. Thanks and Regds, Prasanna Kumar.N, -------------- next part -------------- An HTML attachment was scrubbed...
