96xx and 46xx on the same IIS server?

[victor5908]

I am having a strange issue right now at a site where they are trying to use both phone types.
The 46xx phones are working fine but the 96xx phones simply refuse to get DHCP even though the 242 string is properly administered on the server-I would know-I set the IIS servers up from scratch all of the time.
I thought I saw a doc on this one time but of course now I can't seem to find it.
The phones come up with "DHCP Conflict"
Do you need to add another scope and segregate the IP ranges?
We overcame the issue temporarily by assigning mac address reservations but ultimately would like to have the network function correctly.(Although the phones did say "bad file server' even though I know that is also correct and I can web browse to the directory and Web Dav is allowed?)

Please try in the DHCP server the following.
Right click on the server name and go to properties. Go to the advanced tab and change the value of "Conflict detection attempts" to 2 or 3.

Thanks-I will give that a try
I will have to wait until we have a tech onsite.
I will let you know if we have success.

46XX IP phones use Option # 176
96XX IP phones use Option # 242

normally, 46XX IP phones are setup to be updated from a TFTP server, not a Web server. Only the very latest versions support HTTP upgrading. It is safeest to use a TFTP server for 4600 IP phones.
