Initially, I was drawn towards
CTI for Range testing and optimum location decision of radio trunking controller for
maximum cell range . We were getting numerous complains from customers regarding getting
rings on their radios but not being able to acknowledge them. (explained in more details
in radio trunking section.)
CTI - Computer Telephony Integration. IVRS -
Interactive Voice Response System.
To study and test this
phenomena, we used a CTI based solution.
The CTI was basically used for voice mail application in a wireless network. We used to
dial the landline hooked to CTI and record the message from various locations. The
successful recording or otherwise verified the in/out of range. This finally led to fixing
the controller and its antenna at a central point at
site, covering the maximum range benefiting maximum subscribers.
The CTI system was not
discarded after the establishment of the network. However, We used the CTI based
IVRS solution for recording voice mail for radios, which were currently switched off
or out of range. The CTI based IVRS system periodically dialed the intended
subscriber radio and on getting a response, delivered the message.
The CTI section gives more details about this topic.
