Paging not play full alerts tone

[anhdv1979 (Vietnam)]

Dear All,
I have successfully install the lastest freepbx distro (freepbx 14 & asterisk 15) and also updated to lastest for all modules. I have a problem with paging & intercom without playing full alert tone (play only a half & clients in a group stop). I have also check the quality of the file via music on hold with good quality. Pls help me check the log and give me some suggestion. Many thanks!
