Please do not tag the answers

Please do not tag the answers as correct when they have not solved my issue.

I should say thanks my issue is sorted. not the Admin.

Manish  I read those posts and all in vain. I cleared all configs on the router  did a fresh config with the above configs but still the phone will not register. I have all the files in flash and the config above is what i used the phone still states " Unprovisioned"

I hit the "debug ccsip messages" not much output was coming i will share the output though. 

Request:  can some one walk me step by step with the configs base configs that will connect the phones tell me what i need to get it up and what result i should see when am doing the configs. I will  write erase the router and start from zero. awaiting a response from an expert.

I may just be missing some point. I believe in the basics. Can you experts help me. I dont think this is rocket science! i will do all other dial plans etc all i want it the phone to load... i can pick it up from there. Thanks in advance team!

After bouncing the phone so

After bouncing the phone so many times and trying a config clean up i managed to connect the phone. I also made sure that the TFTP server had the config file with the right mac in it.

Only issue now is that the phone can call out but it can not recieve it give a busy tone to the calling party.

I think some output was cut

I think some output was cut out. now i have the full output.

Issues is all other phones like the 7911 can not call the 7821 phone but it can call all of them. the new 7821 phone call call mobile/landline/international outside the organisation where have i lost it.

when i lift the phone to dial walk me through the dial process, why are these 7911 phones connected to the same system failing to call the 7821 but the 7821 can call the 7911? and 7821 call call any other numbers except here.

Hi,

Hi,

You need to enable the register server command:

voice service voip

sip

register server

Also, please share the output of debug ccsip messages
