Use Quality of Service to maintain prioritization Many devices support Quality of Service QoS tags to maintain traffic priority across the network. It may be beneficial to tag your voice traffic with the appropriate tags, so it can be prioritized anywhere in the network in the event of a saturated link. As such, it is highly important to understand what the expected flow of traffic will be, and ensure that all firewalls have been configured accordingly.
Furthermore, it is important to understand if traffic will pass through some form of NAT, and if so, what type of NAT is in use. The options and limitations of the network may make certain configuration types infeasible. Avoid sending VoIP traffic over non-optimized links As discussed above, VoIP traffic is extremely sensitive to fluctuations in data transmission.
How do I configure the MX to meet my voice provider's requirements? The following questions are commonly posed by voice providers regarding network capabilities: Can Application-Level Gateway be enabled on the MX? ALG is a technology that allows stateful firewalls to dynamically assign ports and broker communication through a NAT.
The MX security appliance is a full-featured stateful firewall that does not have any ALG functionality. Can the UDP timeout value be changed? The MX does have a simple UDP timer function, which will drop a traffic flow after an extended period of inactivity.
This timer cannot currently be changed. However, a timeout would require both peers to be completely silent for an extended period of time in order to take effect.
UDP communication between peers on an active call, for example, is highly unlikely to be dropped due to a timeout. Spiceworks Help Desk. The help desk software for IT.

How does this answer it? Thanks Kenny, One thing It kind of depends which switches you're using and how they handle the phones I have a variety of switches, the catalysts no - they have a specific voice vlan setting so the port doens't need set as a trunk as long as you have the voice vlan stuff set up correctly I have some basic linksys switches where you have the port in trunk mode, with the data vlan untagged and the voice tagged with the appropriate vlan number, this doesn't give you proper QOS required for the voice without some extra work though.
