[cisco-voip] Nortel LAN switches and Cisco IP Phones

[Tim Medley]

A customer just posed a question to me and I couldn't find anything  
on google.

Are there any interoperability issue with using Nortel LAN switches  
with Cisco IP Phones. The CIO for this customer is looking to save  
some $ by using non-cisco ip phones.

My first thoughts were that the Cisco switch provides two things,  
power and voice vlan support. The nortel switches do support 802.3af  
so power should not be an issue. But since CDP is a cisco proprietary  
protocol, the nortel switches won't support CDP which means that the  
phones will not automatically use the voice vlan for voice traffic.  
This just means that the customer would have to do something else to  
segregate and QoS the voice traffic such as an acl.

Are there any other considerations?
