The third element of Spark, Cisco Spark, is Spark call. So Spark call let's you make and receive calls as you would expect it to be. It can use an actual physical handset, or it can use a Spark client running on your PC, your Mac, your smartphone, or your tablet.
Now, Spark call comes in a couple of different flavors. There's the Spark call that comes from Cisco, directly from Cisco, and hosted in the Cisco cloud. And the media for that, the actual SIP connectivity and the PSTN capability, is provided by partners like West. So it's Cisco plus West providing that Spark calling capability.
Now, another way to do Spark calling is what Cisco has called Hybrid. So Hybrid calling leverages a current Cisco unified communications infrastructure you may already have either on-prem with CUCM, Cisco Unified Communications Manager, or something hosted by us like VoiceMaxx CE, which is our VoiceMaxx Cisco Edition product. So you can use that existing enterprise-class calling capability and then extend that out into the other Spark scenarios. The one we've talked about before, the messaging and the meeting. So you have a couple of different choices. You can go with Cisco plus West, or you can go with Hybrid, which in our vernacular is going to equal VoiceMaxx CE.
So we would really recommend you look at Hybrid first and foremost. It has the enterprise-quality, highly tested, proven calling capability. If you want to go into the Cisco and West option, that's more of an emerging set of technology. Something we think is going to be exciting, but maybe something suitable more for smaller-sized businesses to get started with.
