I have Telex Radio Dispatch system I want to integrate this with our Cisco phone system.
Telex has interfaces to the radio networks and the telephone network.
Each user has an ADHB-4. This device mixes the audio. Coming out of the ADHB-4 is a headset for the dispatcher. The dispatcher has a desktop application were they can select different audio sources.
The interface between the phone needs audio tx and rx along with on/off hook switch and ground across 6-wires. The box/application needs the hook switch to answer and hang up calls.
Basically we can not find any information on CCO about Telex Radio Dispatch integration or NENA connectivity to a Cisco phone.
Any and all help is appreciated.
