Hi Developers, Using PJSIP v1.7, I found that the current PJMEDIA tonegen only clears the count of tones once *all* queued tones have been played out. Therefore, the tone queue can fill up quickly, once full it prevents further tones being queued for playout, even though there are less than the maximum tones allowed that are remaining to be played out, effectively blocking tone generation for PJMEDIA_TONEGEN_MAX_DIGITS (e.g 32) tones worth of time. Fix: - Tone queue is now circular. Added "next" field to use as the insert index. - cur_digit is used as playout index. No more tones to play once cur_digit == next. - tonegen->count now stores the actual count of tones in the queue. - Added function to query number of tones queued. See attach diff files. Please excuse the formatting change in c file. -- BRgds, Steve King Design Engineer Zetron Australasia -------------- next part -------------- A non-text attachment was scrubbed...
