DHCP by definition is not a stored value in your phone but is a stored value in your router. Your router would have the ability to have a DHCP reservation (you will need the hardware MAC ID and IP address you want assigned to it. You also can choose to assign the IP address manually in the snom interface. Moral of the story, you won't have the same IP address consistently when your network is restarted. (You may have the same ip 3 out of 4 times, but then another device connects before yours and suddenly the other device has a new ip.) I always assign IP addresses for resource items on a network. (printers, phones, NAS Storage, any server) Yes it is a lot to do when setting up a device and may require some tweaking to do it well. But when your router or ISP goes out of service even for a short period, the stores values allow your network to come up with the most consistent values. (also remember to back up your router settings and your ip phone settings on a external storage) Just in case something happens and the power goes off for a longer period or a firmware update removes the settings you don't have to re-create everything from square one.DHCP by definition is not a stored value in your phone but is a stored value in your router.

Is your phone connecting to a hosted PBX provider or is it connecting to a premise-based IP PBX? Incoming and outgoing calls are usually handled by two separate connections between your PBX and the service provider SIP trunk. Sounds like a registration problem with the SIP trunk. There is nothing you can do from the phone itself to fix this.
IP addresses can either be assigned manually or automatically. When they are assigned automatically, a DHCP (Dynamic Host Configuration Protocol) server hands them out and determines which computer or other device gets which address. This process usually flows smoothly, but there are times when you may need to release or renew an IP address even when using DHCP.
There are several ways to release and renew IP addresses in Windows XP. Each procedure is described below.
From the system notification tray:
1. Right click on the network connection icon in the system notification tray. 2. Select Repair. Windows will automatically release the current IP address, reset the network connection, and request an IP address from the DHCP server. (The new IP address that gets assigned may be a different one from before, or it may be the same one.) From the Start menu:
1. Click the Start button. 2. Right click on My Network Places. 3. Select Properties. 4. Right click on the network connection that is currently in use. 5. Select Repair. (If you choose a network connection that is not in use, Repair will be grayed out.)
For either of the above methods, you can release and renew your IP address manually by clicking Disable instead of Repair, and then right-clicking and choosing Enable. From the command prompt:
1. Click the Start button. 2. Click Run. 3. Type "cmd" and press [Enter]. 4. At the command line, type "ipconfig /release" and press [Enter]. 5. Type "ipconfig /renew" and press [Enter].
6. Type "exit" and press [Enter].
The IP address cannot change if it is a static IP.Only dynamic IP address can be changed.You can check your static IP address in this site Ip-details.com .
To lock or unlock a Snom 300 keypad you will
use the * key. Hold this down until the lock icon appears and hold down
again until lock icon is gone to unlock.
I bought SNOM 300 and i was unable to connect the router in first go. it was keep saying Send DHCP reqt but nothing was happening. i tried even connecting SNOM 300 dirctly to my laptop but in vain. in last i started receiving message Ethernet cable unplugged.
I reset the SNOM 300 to the factory defaults which solved the problem immediately.
Get to the phone menu "configuration-Reset" and select this option. it will ask for the admin password which is 0000. This will fix the issue. try it.
