ASA5505 and Avaya 9620

I have an ASA5505 with Avaya 9620 phones connected remotely as VPN Peers. The phones are having quality issues as well as keep reseting at random times. The phones that are geographically further away from the ASA seem to be having a harder time with everything. Is there anyway to make them more stable?

you say that the only traffic going through the ASA is for the phones, but is this a dedicated ISP connection, or do you have traffic from another firewall/router going over the ISP connection ?

A debug of the traffic that you are seeing from the phones would be helpful. Off the top of my head i have found issues with access lists, QoS as the biggest culprits in these situations. Also just wondering, is the Avaya hardware on the inside or in a DMZ?

I also wanted to add that there is no other traffic going through this ASA other than the Phones. Would you still suggest QoS for that? If so how would I go about doing that?
