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

[Voll, Scott]

I assume that saving money on IP Phones should have been switches.

 

If you want to encourage cisco switches tell them they need twice as
many ports so you can run the phone on one Vlan and data on the other.

 

Really, if bandwidth is not an issue across the LAN then running on the
same VLAN shouldn't be an issue.  I just wouldn't what to support it, or
the security.  And TAC will say go talk to Nortel with any voice issues.

 

Just my 2 cents

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?
