Hi, I am trying to use iLBC codec with both eyebeam and some iphone client. When a ivr is called, the client can here system voice and make dtmf input. but the voice recorded from client's microphone is only noise. The call between 2 clients also have such problem. Sometimes, FS may even got crashed with the following information: 2010-10-08 19:56:21.343750 [INFO] switch_rtp.c:2527 Auto Changing port from 10.20.132.244:18570 to 8 2.132.139.197:19536 alloc: asked for negative size -2147483648 in var.xml, I have added iLBC instead of iLBC@30i, because iLBC@30i is ignored during codec negotiation. <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G7221@32000h,G7221@16000h ,G722,speex@8000h@20i,iLBC,PCMU,PCMA,GSM"/> The git version last week is used in my test. Is there anything wrong with my setup? Thanks.
