[Freeswitch-users] voice recordings by mod_callcenter

Hello, colleagues. I have some problems with voice recordings by mod_callcenter. If I route my call to bridge application the recording is good. If I route my call to callcenter application - recording is no good. I have distorted voice in one channel. It seems that silence slices presents in recordings with some period. See attachment.  FreeSwitch was downloaded from GIT month ago. It works on windows server 32bit 2003. Recordings is in wav format. How can I solve this problem. Does someone have such things? Thank you and sorry for bad English. Evginey.
