OK, I know nothing about configuring Voice GWs ... But I can see a problem in your configuration that could be the cause ... It resides in the DHCP excluded IP addresses ...

In this part you informed the DHCP to not provide IP addresses from 192.168.100.1 till 192.168.100.255
ip dhcp excluded-address explaination from Cisco:Quote:
Router(config)# ip dhcp excluded-address low-address [high-address]
This means, you can either specify low/high IP range, or use only the low IP and the DHCP will consider the end of the subnet is the high IP.
Ex:
Router(config)# ip dhcp excluded-address 192.168.100.100 <<<<<<<< This will exclude the IP Addresses from 192.168.100 till the end of the subnet 192.168.100.255
Router(config)# ip dhcp excluded-address 192.168.100.1 192.168.100.100 <<<<<<<<<< This will exclude the IP Addresses from 192.168.100.192 till 192.168.100.100, this means that the connected hosts will obtain IPs starting from 192.168.100.101
Hope you get my point ...
