Hello. I am currently setting up a FreePBX Call Center with Asterisk. Everything works fine, but when I restart the VM holding my Asterisk distribution and I make a call, suddenly CDRs start getting duplicated, the voices feel robotic and the buttons (with the associated IVRs) do not work (so the caller can not leave a VoiceMail when pressing 2, for example).
The interesting and funny thing is that after approximately 1 hour running, everything starts working fine without doing anything.
Has someone ever had this bug or something similar? Thank you.
