And If pjusa enable vad, the hold music will be played badily, So I have disable it. OSSPhone based on opensipstack has the same problem. But it dosen't matter. Disable it is OK. ---------- ?????? ---------- ????"hlzhangxt <hlzhangxt at 163.com>" ?????2008-04-06 10:27:57 ????nanang at pjsip.orgpjsip <pjsip at lists.pjsip.org> ??? big bug in pjsip A is pjsip usa, B is grandstream hardware ip phone. The Server is Asterisk. The Hold music is sent from asterisk.( /var/lib/asterisk/moh). After asteirsk play on hold music to A(for example, B press hold key, or B transfter A to another phone), then A is easily(I mean, sometime a can hear, sometime A is deaf, and the possibilty that A is deaf is much more than that A can hear) to be deaf. But if I delete hold music files from linux, then asterisk can not find any hold music to play. Then everything is ok.(ie, the problem is that, if A listen to some sort of music, then A is easily to be deaf, not definetly,But usually) I also tried sipek2, same problem exits. I have to make A to do unhold to resume normal. I also tried another opensource phone OSSPhone based on opensipstack, it has not this problem. ? ? ? ? ? ? --- ? ? ? ? ? ? ?166 ? ? ? ? ? ? ? -------------- next part -------------- An HTML attachment was scrubbed...
