[asterisk-users] Audio going blank for a few seconds andthencomes back. What could be the reason?

[Zeeshan Zakaria]

Rob, as I mentioned before, here the main trunk is a T1 PRI on which this
customer face this problem. Local phones are connected to the Asterisk
server on their local network, and then calls go through the PRI. There is a
VoIP trunk too only for long distance, and same problem happens there. So I
was thinking its the network issue.
