It seems that the tftp-binding is not set up correctly. The CME can not find the file requesting by the CIPC end point.

You have to look the new TFTP server's address that you will need to correct on your ip phone under network configuration

Thank you for your replay.

I added the following and that problem was fixed:

tftp-server flash:g3-tones.xml alias United_States/g3-tones.xml

tftp-server flash:us-mk-sccp.jar alias English_United_States/mk-sccp.jar

tftp-server flash:us-tc-sccp.jar alias English_United_States/tc-sccp.jar

tftp-server flash:us-td-sccp.jar alias English_United_States/td-sccp.jar

The remote phone was an 7911 and now is a CP-7941 registered as mtp with the following configuration:

ephone 30

device-security-mode none

mac-address 001E.135D.64E0

username "user9" password 226


type 7941

The problem is that the phones show "registering".

Any help on that?

Thank you.

I am unable to solve the problem!

I am using a site-to-site vpn with 2 pix501.

Can it be an access-list isssue.

The remote phones ip is

Office vlan1 (DATA) ip add 10.10.10.x

Office vlan100 (VOICE) ip add 10.10.100.x

Office router 2811 cme 7.0 ip add

Closed ports 1720 & 5060.

Any help?

Thank you.
