I suppose that you have QoS for your voice traffic. There's a FIFO queue for traffic entering the encryption engine and this causes jitter in voice. So, I would advise you to use "tunnel pre-classification" feature to copy the packet priority value to the tunnel header.

Just a question about this fifo qos pre-classification. What kind of QoS will you be able to achive with this ?

How do you configure the QoS settings of the protocols ?
