I have a 3845 router that has been working fine as a VOIP only, DHCP server. I just deployed 5 new VOIP 7960 phones and neither of them could attach to the Router based DHCP (VOICE VLAN 7) server when coupled (on the switch port) with vlan 8 (data vlan), however when the switch port has vlan 9 (another data vlan) the VOIP phone is able to reach the proper router based DHCP server that supplies IP's to the VOIP phones.
* vlan 8 has a Microsoft DHCP server that supplies IP's to the PC's...however, it is also giving IP addresses for my VOIP phones and I don't want that.
VOIP VLAN W = FIRST OCTET

I have 62 total ip's in my dhcp scope, and I have 28 leases still available
GW-RTR#sh ip dhcp pool
Pool VOIP :
Utilization mark (high/low) : 100 / 0
Subnet size (first/next) : 0 / 0
Total addresses : 62
Leased addresses : 34

1 subnet is currently in the pool :
Current index IP address range Leased addresses
W.13.103.163 W.13.103.129 - W.13.103.190 34
W = first octet
Summary : I have two problems
1. when the VOIP phones look for a IP it should go to the Router DHCP (W.13.103.129 255.255.255.192) - instead it finds its IP from the Microsoft server DHCP and will not find the Cisco Call manager
2. Not mentioned above I have several 7960 phones and I can do the factory reset on them all except this new batch, on these new 7960 phones I can't do a factory reset ....below is what mean by a factory reset
From CISCO website
Reset the 7940 and 7960 IP Phones to the Factory Default
In order to perform a factory reset of a phone if the password is set, complete these steps:
Unplug the power cable from the phone, and then plug in the cable again.
The phone begins its power up cycle.
Immediately press and hold # and while the Headset, Mute, and Speaker buttons begin to flash in sequence, release #.
The Headset, Mute, and Speaker buttons flash in sequence in order to indicate that the phone waits for you to enter the key sequence for the reset.
Press 123456789*0# within 60 seconds after the Headset, Mute, and Speaker buttons begin to flash.
If you can help I would appreciate it
