I have set up Phone Proxy on my ASA 5510 according to this guide:

The phone downloads it's configuration from the CUCM, but somehow it's just stuck on "registering".

My ASA is running ASA 8.0(4) and ASDM 6.1.5.

I have attached debug output with "debug phone-proxy tftp" and "debug inspect tls-proxy" turned on, when the phone boots. after this the phone is just stuck on "registering"

any help is greatly appreciated !

Best regards

Looking at the debug you have sent, looks like the phone is not able to setup a SSL connections to the ASA.

Can you tell me what is the model of the phone? Also, have you tried to register this phone inside the network and does it register?

Also, you can refer to this link for help on how to configure ASA for phone proxy. Please pay special attention to certificate install on ASA.

Have you tried resetting the TFTP service on UCM where the phone is attempting to download its configuration? We have found that this cleared up our issues.

what settings have you actually done on the phone itself? We have the same issue as you had but in our case it looks like the phone can not receive the CTL file from the ASA.
