A Phone’s Gotta Connect… it takes 2 or more!
| System | Vendor/Brand | Type | # of Lines | Notes | Pic |
| Definity ECS R9 (Compact Modular Cabinet hardware) | Avaya | Digital PBX | 8X32
1 8 CO Line 1 8 DCP Line 1 24 DCP Line 1 16 Analog Line (licensed to 300 stations) |
Acquired in 2015, a vast majority of the desktop hardware in the following years came for free.
Caller ID is supported but would require forklifts between the CO card and the Analog line |
 |
| ICP 3300CX | Mitel | IP PBX | 16 licensed IP stations, 6 CO trunks | Christmas gift in 2015 |  |
| 1760V | Cisco | IP PBX | Up to 24 Cisco’s IP and or SIP extensions, 2 outside line via VICFXS2 | Acquired in 2013, not in production for year | |
| G250DCP | Avaya | TDM/IP PBX in a Rack Sized Gateway | 12 DCP ports, 2 analog station, 2 CO lines, supposedly 16 VOIP stations | If there is no media server that handles PBX, the Avaya has Survivable system inside, but it’s very primitive. | |
| C2801 | Cisco | IP based VOIP routing | Up to 42 SCCP or SIP extensions | It used as a primary call processing for old VOIP phones and to connect to Phunco | |
| TVA24 | Citel Portico | Analog Telephone Gateway | 24 FXS ports
The Gateway can be tied to have multiple phone numbers dialing the port. |
System prefers to interconnect to an Asterisk type of PBX. No survivability. You can’t call another phone number on the gateway, it must route through the SIP server over IP | |
| Issabel | Asterisk derriative | Unified PBX system | Limited to the server’s compatibility | The system is virtualized to interconnect all the VOIP and legacy system. It has a modified interface that was derived from Elastix | |
| FreePBX | Asterisk derriative | Software based IP PBX | Preferably under 100 | This is the basis for PHUNCO. I am using version 18 or so so I can use chan_sip because PJSIP renders half of my SIP phones to not work | |
