Host Not Found - Extension Mobility problem

[sayeedibrahim]

Hi

I have enabled extension mobility.

I understand that the service is configured properly as some users are able to login/logout successfully and when I check the URL in the settings of their IP Phones it displays the IP address of the server.

For some users, when I press the service button it displays message "Host Not Found" and when I check the URL in the settings of their IP Phones it does not display the  address of the server.

I have already tried the common mentioned solutions but no luck.

1. I have already made changes in Enterprise settings and replaced the CCM Hostname with IP Address.

2. I have added an entry in DNS server

3. Re-configured the service

4. Restarted the IP Phones, services [TFTP, Extension Mobility]

5. Rebooted the server

The only thing I missed out on was changing the hostname to IP address.

When i go to System---Server ---Find --- it displays the hostname. I am afraid of loosing service if I change from Hostname to  IP. The application itself warns from doing the same. I am managing the server remotely and have no technical assistance at the site.

Appreciate guidelines from all you techies out there.

Thanks

I didn't catch what models phone you have - but make sure you are telling the phones what domain to use when they do a DNS lookup.

If your using an IOS device for DHCP - make sure you have in your "ip dhcp pool Voice" a "domain-name mydomainx.com"

Name resolution should work fine and my personal recommendation is to stick with name resolution and use the CUCM server name instead of IP address.

Hello Everybody

The strange thing is that Services are working for some users and not for all users.

Check attached file and take at the loads info.

IP Phone with DN 9556 has all the services working while the other IP Phone with DN 9669 does not have the services running.

Hi

Those two phones are running completely different firmware - the non working one has not upgraded.

Can you screen grab the 'network configuration' page on the phones? It looks like one has not been able to upgrade for some reason. Do they both have the same TFTP server configured? Can they be PINGed from the TFTP server?

I do not have a seperate TFTP server.

Both phones are using CCM as the TFTP server.

On the IP Phone with old firmware I tried basic reset [erase option from settings menu on the phone]  but no changes so i tried factory reset but now this phone keeps rebooting.

Here is the network config info:

Any hands on experience how i can upload new firmware on the CCM and IP Phone.

[Aaron Harrison]

You don't need new firmware on the CCM; you need to make sure the phones on your network that have not upgraded can access the firmware you already have.

Pls check the below msgs that i see under the Device Logs - Debug Display

Hi

Looks like you have a load that falls foul of the problem listed here:

Try upgrading them to an interim version of firmware as discussed in those posts, and then upgrading to 8-5-2SR1S.

This is noted in the release notes for that firmware:

I have opened a TAC case and they suggested the same like you Aaron.

I will update once they solve the problem.

Thanks!

[sayeedibrahim]

All services are now working on the ip phones after upgrading the firmware

All available IP phones had old firmware version 7.x

The new Call Manager 7.1 had phones firmware 8-5-2SR1S

I uploaded SCCP11.8-2-2SR3S on the CCM . IP phones did an auto upgrade to 8-2-2SR3S

Then changed the default device firmware back to 8-5-2SR1S and this time ip phones upgraded to the latest version a/v on the system

Thanks all for the support.

Thanks Aaron,

it also helped me, as the telephone was not used for a while and the firmware of cucm has been upgraded meanwhile. I have done a factory reset on the phone, took the new firmware and it worked. Thank
