4331 : DHCP pool not offering optoin 150 although it's configured

[dennis.maston1]

I am having a DHCP scope issue with it not offering option 150 although it is configured.

4331 Version 15.4(3)S4

ip dhcp pool NewVoice
 network 10.28.26.0 255.255.254.0
 default-router 10.28.26.2
 option 150 ip 10.146.1.100
 dns-server 10.151.2.52 10.151.2.56

All IPs are talking, I grabbed packet caps First at my firewall which never saw any tftp traffic.
I spanned a phone port and watched the dhcp process. And in the bootstrap it shows all the options;
53, 61,54,1,3,6,255.  However it does not show or offer the option 150.

Any ideas or assistance is appreciated.

hi,

just to cover the basics, did you configure the voice VLAN on the switch?

can you ping 10.146.1.100 from source IP 10.28.26.2 on the router?

can you post a sanitized show run output?

Thank you for your help, once I stepped back I realized I had no route on my router for the TFTP server. Once I added phones grabbed configs and came up.
