Cannot use Jabber soft phone with Cisco Agent Desktop

[michael.lax1]

I work on a help desk and use Cisco IP Communicator instead of a physical phone; I cannot upgrade past Jabber 12.0 because it no longer integrates with CIPC.  I would like to move to using just Jabber, but from what I understand the Cisco Agent Desktop only works if Jabber has a single line.  This makes absolutely no sense; if Cisco is retiring CIPC to replace it with Jabber, why make it impossible to actually do that?  Jabber multi-line has been available for three versions (12.0, 12.1 and 12.5), so this is not something new.  Any input on this would be appreciated.

It’s worth mentioning that CAD/CSD reached end of SW maintenenace in 2016 (https://www.cisco.com/c/en/us/products/collateral/customer-collaboration/unified-contact-center-express/eos-eol-notice-c51-733721.html). No one has looked at or tested that code in years.

Having said that, CAD supported multi-line on physical phones and only did CTI subscription of up to the first four lines. It’s likely that this looks identical for Jabber multi-line since CCX is seeing it through the lens of a CTI Manager subscription. Give it a try and, if it works, feel free to use it. You’re already self-supporting at this point due to the EoL software; it’s a matter of how much risk you’re comfortable accumulating.
