When trying to debug the issue instead of trying our client (Blink) I tried pjsua 1.5 and got the same results, at least on MacOSX. I'll try in on Debian and report back. I went through the bugtracker and found the bug you mention, but it's already included in the 1.0 branch (which Blink uses) so I didn't patch anything. So, from what I've understood (Nanang, please correct me if I'm wrong) pjsip is 'adapting' himself to use 16KHz. I'll capture the RTP in a test call (sip:wbdemo at conf.zipdx.com) and report back what I can see in the RTP timestamp. Thanks again for your help. Best regards, -- Saul Ibarra Corretge AG Projects
