Hi all, I think there is a bug in the 1.6 version. The bug is in PJSUA when detected a DTMF digit, that is when the remote dial a dtmf the on_dtmf_digit callback is not called so the dtmf is never detected. I test the same using the 1.3 version and it functions ok. Any ideas? Thanks in advance, Jose -------------- next part -------------- An HTML attachment was scrubbed...
