Guys,

Apologies if that has been asked before, I think I have read the answer somewhere but cant find it. What is the rule for device profiles with reference to phones e.g Is it ok to configure a device profile for a 7961 phone but use a 7941 instead. Something tells me due to the template (6 buttons for 61 and 2 for 41) this is not best practise. Can someone confirm this.

Many Thanks

Paul

Hey Paul,


Hope all is well! Here is a clip that describes the behaviour;


On authentication, if the login profile matches the login device (that is, the user has a user device profile that is configured for a Cisco IP Phone Model 7960 and logs into a Cisco IP Phone Model 7960), Cisco CallManager Extension Mobility behaves:


•The phone automatically reconfigures with the individual user device profile information.


If the user has one user device profile, then the system uses this profile. If the user has more than one user device profile, the user can choose the user device profile that will be used from a list.


•The user can access all the services that the user configured on the device profile.


If that same user logs into a Cisco IP Phone model where the user does not have a configured user device profile, the login profile will not match the login device on authentication. In this scenario, the system loads the device profile default for that phone model onto the phone, and Cisco CallManager Extension Mobility works as described here:


•The system copies all device-independent configuration (that is, user hold audio hold audio source, user locale, userid, speeddials, and directory number configuration except for the setting "line setting for this device") from the user device profile to the login device.


•The system uses the device profile default for that phone model for phone template and softkey template configuration and, if the phone can support addon modules, for the addon module.


•If the phone model supports Cisco IP Phone Services and they are configured, the system copies the services from the user device profile.


If the user device profile does not have Cisco IP Phone Services configured, the system uses the Cisco IP Phone Services that are configured in the device profile default for the login device that is accessed during login. If parameters exist for the subscriber service, the system copies the parameters from the device profile default and the parameters may not reflect the correct information.


For example, the following scenarios occur when a user who has a user device profile that is configured for Cisco IP Phone Model 7960 logs in to a Cisco IP Phone Model 7905, and the device default profile is loaded on the phone.


•The user can access the user's hold audio source, user locale, userid, speeddials and directory number configuration. The user cannot access his phone line setting; the system configured the phone line setting from the device profile default that is configured for the Cisco IP Phone Model 7905.


•The user can access the phone template and the softkey template of the Cisco IP Phone Model 7905.


•The user cannot access an addon module because Cisco IP Phone Model 7905 does not support it.


•The user can access Cisco IP Phone Services if they are configured for the Cisco IP Phone 7905, but, the parameters from the subscriber services will reflect the device profile default, not the parameters that the user chose on the User Options window.

if you plan to do so what you need to configure are default device profiles for all phone models that could be used.


if your profile is for a 7961 but you only have a 7941 on other office, then create a default device profile for 7941 model and then you can use it also. this avoids creating a device profile per model, per user.


you certainly can use it, just have in mind that not all phones have the same amount of lines and will affect which lines are on the phone

Java,

Thanks, this is what I thought. I found the source of my query. One of the CCVP books for CIPT states you cannot use a user device profile on a 7941 if you have configured it to be for a 7961. But the few docs I found on cisco sort of say this is not true, as you do, by stating as long as the default profile for that phone type is in the system then you should be able to use it.

Thanks

Paul

Rob,

Thats the sort of information I was looking for thanks for clearing that up.

So the message is if you dont configure a default device profile for each phone you have on the system, then EM will fail if the Users profile has no default profile to fall back on if they are using a different model of phone than that they have be configured for.

Once again many thanks


Paul
