Right.
What cud be the cause of the call drops?
There could be a variety of problems. Please enable logging of the Server side and monitor to see the cause of call termination.
Also is there a tool i can use to measure VoIP perfomance.
VOIP is sensitive to jitter. One of the causes of jitter can be packet-loss. You may want to conduct a couple of tests (end-to-end) tests using something like iperf to see what throughputs are available. Secondly monitoring the link using smokeping or something like mtr would tell you where the packet-losses are.
Also note that i have not done any QoS because the calls are too few
Whats the current link utilization like? Regards, Michuki.
