ASA Phone Proxy Setup Issue

[Charlie Mayes]

My phone was working fine now it is not. I keep getting the errors below. Does anyone know what is going on?

P: Intercepted Data Block 15 from inside:10.7.7.253/33217 to  remote phone outside:50.73.73.66/18446
Error: block # is 15, expecting 1

PP: Intercepted Data Block 15 from inside:10.7.7.253/34234 to  remote phone outside:550.73.73.66/43043
        Intercepted Block 15

Hello,

It looks like The ASA is receiving TFTP packets from the CUCM out of sequence, or perhaps some data packets are being lost. I would suggest setting up captures on the ASA to confirm what the debugs are showing, as well as at various points in the network between the CUCM and the ASA to see if something is getting lost or incorrectly routed. If that doesn't help narrow it down, I would suggest opening a TAC case.

Hope that helps.
