whoops, reading better current config:

- don't change fa0

- configure a vlan100 interface and give it a different network address

- configure that address as ip source under telephony-service

- configure network, default router and option 150 for the above under dhcp pool phone

if you have problems with the PC connected to phone not having connectivity, change mode to trunk under all FA ports.

if you give static ip under fa0/0

then you have to connect this interface to the inbuilt switch for the phones to reach default gateway?

There is no need to make any connection.

Just configure the dhcp pool for the phones so that default gateway is the VLAN address of the router.

thx..

i got it.

i was just replying to your first solution which was to give ip to int fa0.
