[cisco-voip] phones getting IP from data VLAN

[Curt Shaffer]

I have a series of phones on the network that seem to keep getting an IP
from the data VLAN DHCP server. All of my switch ports are configured the
same. It's just some work and some don't. I have searched docs and the web
about this and found that there are some issues with older firmware but the
thing is that I have phones that did this at first and work fine now and
some phones worked fine at first and now do this. It's really quite odd. Has
anyone seen such an issue or got any advice? I'm not onsite so I can't
easily span the port and grab a capture today. DCHP is coming from the CME
router just FYI.

 

Here are the specs:

 

Phone models:

 

7940 and 7960

 

Version :

P0030301MFG2

 

Switch IOS (x2):

 

Cisco IOS Software, C3560 Software (C3560-IPBASE-M), Version 12.2(35)SE5,
RELEASE SOFTWARE (fc1)

 

Router IOS:

 

Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version
12.4(15)T1,RELEASE SOFTWARE (fc2)

 

Thanks

 

Curt
