Comments: | By: lists (lists) 2004-09-14 04:05:33 my trunkfreq is set to 30ms, when i set it back to 20ms there is no more problem. By: zoa (zoa) 2004-09-14 05:59:36 hmm.. why did you change it? And did you change it on both ends ? By: lists (lists) 2004-09-14 07:54:49 I changed it to reduce the bandwith used by this trunk (and of course changed it on both ends) By: zoa (zoa) 2004-09-14 08:05:12 hmm.. i don't think that would make any difference in bandwidth... By: Mark Spencer (markster) 2004-09-14 08:26:53 Changing trunkfreq could definitely break things because if you're sending 20ms packets but have a trunkfreq of 30ms then you're manually introducing jitter. By: zoa (zoa) 2004-09-15 03:57:45 Kram, Just to get something straight, when using iLBC, will asterisk send 20ms packets or 30ms packets ? From my measurements, with iLBC, asterisk will send 70pps for a while, then send 60pps then some more 70pps. most other codecs use 100pps fixed. (except for : g723.1 - 60/70pps and lpc10 - random). Does this mean that for iLBC we need a different trunk frequency ? By: Brian West (bkw918) 2004-09-15 08:23:32 ilbc is a 30ms codec so I think that might need 30ms? By: zoa (zoa) 2004-09-15 08:52:25 i asked kram before, and he claims thats not the case bkw. i think we need a little diagram to understand all this :) By: Brian West (bkw918) 2004-09-24 06:57:30 And how many times has kram said one thing to only say the exact reverse a few days later :P Its not really his fault... haha he is a very busy man. bkw By: adam (adam) 2004-09-24 08:30:20 *'s iLBC only allows 30ms frames, although the spec allows for 20ms too. So setting the trunk size to 30ms should work By: Mark Spencer (markster) 2004-09-27 20:33:45 Is this still the case? By: Mark Spencer (markster) 2004-10-02 10:09:11 Bug poster seems to have lost interest. Should be fixed by stevendavies patch earlier just before 1.0 anyway. |
