We currently have Linksys SPA922 and SPA962 phones that we bought a while back and have tested for integration with CallManager. Our lead engineer tells me that it is more labor intensive to configure them than a 79XX series phone. Can you provide a technical contact that may be able to assist in this review process? Do the SPA 5XX phones differ in how they are configured or would it be correct assuming that if we can get the SPA9XX to work we should be able to get the SPA 5XXs to work?
It is certainly true that configuring CallManager to support the 7900 phones is significantly easier than configuring support for an SPA phone. CallManager does not, and has never provided any specific support for the SPA phones, beyond them being configured as a third-party SIP handset. As such, it does not automatically generate configuration files for the phones the way it does for the 7900 phones. There are no plans at this point in time to change this.
In terms of getting technical support for this configuration, there is no formal support for this setup. However, if you post questions to the support community you will usually get an answer. In particular, this thread might be of interest:https://www.myciscocommunity.com/thread/2498.
Regarding the SPA5xx phones, in general they offer a superset of the functionality of the SPA9xx phones, so you should be able to deploy an SPA5xx wherever you have been previously deploying an SPA9xx, using the same configurations for both phone types.
