# configure terminal
# interface [INTERFACE]
# switchport mode trunk
# switchport trunk encapsulation dot1q
# switchport trunk native vlan 1
# switchport trunk allowed vlan add 1,[X]
# switchport priority default (0)
# power inline auto
# end
# write mem
Where [X] in the last line is your Voice VLAN (Found in System IP Configuration in the Mitel)
Where [INTERFACE] is every interface with a phone attached, and the uplink to the Mitel 3300
The above will allow data traffic through (VLAN 1) and Voice traffic through (VLAN X). Mitel phones and the controller use the 802.1p tags to prioritise traffic, the switch will obey this and give untagged traffic a default of Priority 0 (Equivalent to 3)

Some Cisco switches don't like 3rd party devices even though they are supposed to be 802.1af compliant. You may want to try the Mitel Cisco power dongle -- Mitel part # 50003734 (10 pak) or 50004023 (single dongle)
Also, that 3500xl supports only 15.4 watts of power per port without a RPS (additional power supply) . From the Cisco document: When a device needing power is detected, the switch determines the device power requirements based on its type or uses an initial allocation of 15.4 W for power budgeting.
Here is an excerpt from the Mitel Engineering Guidelines:
Mitel 3300 power dongle (Cisco compliant)
Certain older Cisco network switches are capable of providing power but are not fully
802.3af compliant. In this instance, a separate 3300 Power Dongle (Cisco-compliant)
used to get powered operation. The 3300 Power Dongle (Cisco-compliant) may not be required
when powering Mitel phones behind a Cisco Catalyst 4500/6500. For this to be the case,
must ensure you are using an 802.3af-compliant version of the 4500/6500 switch.
And more -- this is referencing particular compliant switches...of course, all HP Procurve switches are compliant and cheaper :-) and....come with a FREE lifetime warranty.
Your Cisco switch is not really mentioned so it sort of appears that you need the dongle.
Cisco
" Cisco 3560 series
" Newer versions of Cisco 4500 series
" Newer versions of Cisco 6500 series
Note: Some of the older versions of 4000 and 6000 series are not IEEE 802.3af-compliant
(check before using). The older 3524XL-PWR and 3550-PWR are not fully compliant
and have been replaced by the newer 3560 series. For switches that are not IEEE
802.3af-compliant, use the Mitel 3300 Power Dongle.
Regarding power draw, which may be a consideration for you later as you add phones, a 5340 (the biggest power consumer so use this as your calculator) draws a maximum of 5.8 watts of power per phone. This is an important consideration if putting Mitel VoIP or any power demands on the let's say, every port of a Cisco switch.
