Cisco ISR 871 and VOIP

Hi I have an 871 that has the following config. The phone connected behind the VLAN 174 will not communicate with the Cisco Call manager. IS there anything I need to do to have the phone communicate with Call manager? The VPN works fine.

Hi, from the CM, can you ping the phone and viceversa ?

If you're not able to do that, the VPN is not set properly, or you have other routing problems.

Unless you have it configured manually on the phone, you will need to configure a TFTP server address in the DHCP pool, such as:

option 150 ip 1.1.1.1

Hope this helps. If so, please rate the post.
