[cisco-voip] Internet IP phone connect through PIX Firewall

Manoj:
Is your PIX giving out DHCP addresses?  On my PIX 501, I have it setup
as a DHCP server and these are my DHCP commands:

dhcpd address xxx.xxx.xxx.xxx
dhcpd dns xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx
dhcpd wins xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx
dhcpd lease 36000
dhcpd ping_timeout 750
dhcpd domain internaldomain.com
dhcpd option 150 ip xxx.xxx.xxx.xxx <--TFTP address
dhcpd enable inside

Hi All,
Does any one has configured PIX firewall to connect internet IP phones
to Call Manager. I have configure firewall to open all the port which
CCM need but still no luck. Bellow is the config of my PIX. Am i missing
anything? 

Here is the link I refered to open the TCP and UDP Ports
