Scott,
You can add customer options to Windows DHCP. I had to
add options 150 for our Cisco phones. Open DHCP under Administrative
Tools. Right click your server and left click Set Predefined Options.
Give the options a name, enter code 120, and specify what type of value
it will contain. Once that is done you can configure the global scope
option or individually for each scope. Also, what register expiration
timer are you using on your phones?

Hi,
I just want to add some information to this question. If I am behind a
router could this issue have anything to do with DHCP Option 120.
I notice that this could be needed in some cases. But my phones worked
when I first brought them up then they lose contact overtime and I am
unable to make calls.
So I was wondering if DHCP Option 120 would help? The only problem I
don't see this option on my Windows 2003 server R2. How would I
configure this if this is needed?
Thanks
Scott

Subject: sipx version 3.11
Hi,
I have sipx version 3.11. On a daily bases I need to reset the sipx
server in order for my phones to come up so I can make a call..
I reset the server and the Siemens optipoint 410 phones come up and go
right from saying they are registering to
coming up so I can make a call. I am not sure how long it takes for the
phones to go from being up to trying to register.
I have been waiting for 4.0 so I can upgrade to the latest sipx server.
Has anybody else had this issue. I am wondering if it has something to
do
with dns. Is there anything special I need to do on my dns server. I
have created forward and reverse lookups but this hasn't helped my
issues.
Thanks
Scott
