Hi guys
I would like to know if it is possible to set a Phone Service (specifically Extension mobility) using a FQDN in the Service URL
Currently I'm using
http://10.10.14.10:8080/emapp/EMAppServlet?device=#DEVICENAME#
But I want to start using something similar to:
http://extmobility.office.com:8080/emapp/EMAppServlet?device=#DEVICENAME#
but is not working the ping works from my PC and from the server, in the examples you can se that is load balancing correctly.
C:\>ping extmobility.office.com
Pinging extmobility.office.com [10.10.15.10] with 32 bytes of data:

I even tried using http://www. but nothing works, any idea of the correct setup for this?
I checked
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a0080a80386.shtml#t1
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_0_1/ccmfeat/fsem.pdf (Page 17)
All the links said that is possible, but none of them gave an example of the correct configuration.
Thank you!!!

Although Cisco recommend not using round robin it can be the best option available if the customer does not have a load balancer available. The only other alternative is configuring a backup EM service, subscribing the phones to both and hoping that the users will remember to use it. I do sometimes use round robin and explain to the customer it is a bodge.
Anyway your URL looks fine. I would try SSH'ing into a phone and trying to ping the hostname. Instructions on how to do this are available at the link below:

If you cannot ping it by hostname then check your DNS setup.

Does the phone have a DNS server in it's DHCP lease?
Did you define a Secure URL on the EM service? If yes, remove it for a moment as that would subject it to the ITL and lead us down a different troubleshooting path.
PS- Are you using a real load balancer or DNS round robin? The SRND explicitly recommends against the later.

Yes, they do, in fact are the same for my PC.

No, is unsecured.

I'm not quite sure... let me back with you tommorrow for this.

Hi Jonathan,
I double check and yeah... we are using DNS round robin.

Sorry for the BIG BIG delay with this guys!
I tried what James suggested... I can start the ssh sesion but I cannot access to the phone, I tried with:
default-cisco
default-cisco123
default-admin
default-123cisco
I know "default" is the correct username, but I don't know the password

Hi guys, just an FYI
at the end I decided to create two instance of Ext mobility, because everywhere I looked said that is not recommended to uses DNS server.
Thanks for all the help!!!
