(I am well aware that the words "Cisco" and "Low Cost" do not go together. Lol.)
We have an old BE6000S running CUCM and Unity. It's a couple years old, and was originally only set up for internal phone calls and voice mail storage for about 60 phones. (The thing seems ridiculous overkill for what it is doing. The video capabilities will never be touched.) The BE6000S is EOL, due in 2022 and we will drag it along to the very end.
Due to coronavirus, people are now working from home and I am trying to determine what I would need to do to provide soft phone VOIP access from their smart phone to CUCM.
We do not use Cisco for anything other than the phones inside the building. There is a Juniper SRX managed by our ISP that does our routing and VPN services.
I have looked at Jabber but it seems the main intent of Jabber is to sell me a pile of really expensive Unified doodads to make it function. I am not interested in blowing $10,000 on an Expressway device and then another $10,000 on an ASA firewall just so that about ten people can use Jabber as a soft phone outside the building.
It seems like it may be far less expensive for me to just forget about using Jabber and instead use a generic SIP softphone app that can work with the generic non-Cisco VPN provided by the SRX, to join as a generic VOIP phone device in CUCM.
