CISCO IP TELEPHONY CME 7821 PHONES XML PARSING ERROR

[samsam926]

Dear All,

                   my cme IP address is 10.0.40.1 and all phones are registered and working fine. To provide telephone lines to another partner company I configured another lan IP 10.10.20.1 on another interface and configure dhcp in that range . Now the sccp phones are connected and working well, but the 7821 sip phones are showing xml parsing error and when I checked the debug messages , I can see  connection  "unauthorized" for the 7821 phones . So trusted the subnet in trusted list, but still the same error exist. Can anybody suggest me a solution

Phones in the same LAN of the CME. If yes then remove then apply these commands and restart the phones

voice service voip
 sip
  registrar server expires max 60 min 3600

voice register global
no authenticate register
no authenticate realm all
 create profile 

If the phones are in remote LAN, then apply these commands and restart the phones

voice service voip

When there is no dial tone, can you share the output of the command show voice register poo all brief.

Seems that the phone isn't registered and thats the reason you aren't getting dial tone.

Is this the case for one phone or all phones.

Dear Mohammed,

          When I check 

 sh voice register pool telephone number 9882  I get the output as registered , but physically phones in registering mode . 

All the sccp phones are connected in the same lan 

All other sccp and sip phones in my ip address 10.0.40.1 255.255.254.0  lan working perfectly 

  Now am away from site , so I cannot paste the output

In my case, setting source interface to be loopback solved SIP phone registration issue.

I do not know why, but there will be a bug.
