You did not attach any file from what I can tell. If you want us to check your configuration please provide it in an attached text file. First thing to check, does your version of IOS have support for the 7811 phone model?

Add bind statements to voice service voip / sip and I’m not sure if you need these.

authenticate register
authenticate realm all

Remove the below, if you use authenticate register you need to configure username and password under voice register pool.

authenticate register

 authenticate realm all

2.12.0.0

removed the authenticate commands . load command , removed the extension from the file name, still no luck. Phone keeps showing reg in progress. show voice register shows the number of attempts to register. getting reg send failure.  have reset the phone and rebooted. any other shots worth trying. thanks again. 

this keeps showing up on tftp events.

Can you do a factory reset for the phones and try.

Make sure you have the dn associated. After making changes make sure you issue create profile under voice register global.

2.12.0.0

2.12.0.0

DN is linked to the pool created. Did factory reset multiple times . doesnt want to work still. 

[Roger Kallberg]

Is this the only model of phone that you have this problem with, are other models of phones operating as they should?

Make sure that you have followed all the steps in this document for how to configure CME. Cisco Unified Communications Manager Express System Administrator Guide 

[Nithin Eluvathingal]

When ever you make changes make sure you issues create profile

[rajkamath]

create profile command runs , but keeps throwing error about not able to find cisco jabber-config.xml file.going through the docs to ensure nothing is missed. if anything else to look at like debug logs which could point in the right direction, would be helpful.

finally managed to get it working. did the binding to interface, added username and password with the authenticate register command. and issued create profile . worked like a charm. not sure what caused it to not work earlier. incoming calls are working properly. need to understand the outbound calling feature as the next step.  thanks again
