I'm deploying some Talkaphone emergency phones on my 200ICP. The phone dials an extension hosted on a 3300, and the call works as expected. However, when the remote party hangs up, the line stays open on the phone. There is a fast-busy, then eventually the phone's timer expires and it hangs up. Talkaphone support tells me their phones need a CPC. Can the 200ICP provide this? They also mention I could use a Viking CPC-1, which I may have to use if I can't get this to work.
From the device manual:"If connected to a PBX, your extension must provide: at least 24 Volts at 20 mA off-hook (no current is drawn on-hook) either a disconnect pulse (voltage drop at end of call) or 30-seconds of silence after hang-up (no re-order or howler feature)."
Any ideas?
Thanks in advance!
