The Mitel is default, and the 5 IP phones are in the Mitel sub-net. The voice mail ipocket is .3 and the pbx ipocket is .4. The router has been changed to 1.245, and is there to allow the pms company access through the internet. I can see through maint that the voicemail is "talking", and when the pbx ipocket is powered it's "talking", but won't pass data unless un-powered. Will double-check protocols today. Thanks for your help.
