I am looking for a little guidance.... I am new to VoIP. I have 2 separate buildings. The demarc is on the second floor of the main building with a cisco ME 3400 Router. The service building is just across the parking lot. All 4 switches are HP ProCurves. 3/ 5406zl and 1/5412zl. The phones are Avaya, unsure of the model. There will be appr. 300 phones. The vendor will be using Avaya IP Office.

I am a little confused about the setup and would like some clarification before I start. It would make troubleshooting easier down the line.

1.Create the the voice and data vlans on all 4 switches. I think I got that.
2.What is needed to connect the 4 switches? I understand trunking is link aggregation in Hp terms.
3.link aggregation is where the confusion is for me.

Thanks in advance
