TalkAnytime Quick Start Instructions System Examples
Technical Configuration for Specific Extension Calls via IVR
Alternative Method to Access Multiple Extensions.
In this example, we used an IVR to allow access to various
extensions of the PBX. Specifically, the end-user used the TalkAnytime keypad to dial digits in response to instructions
given in the IVR’s outgoing message.
Be aware that external extensions could have been reached in another way without an IVR: the end-user could be
allowed to dial any extension on the PBX from the TalkAnytime keypad (determined by the setting Digits=Yes in the
URL). In that case, the PBX would have to be configured in a way that blocks PSTN calling by the PBX extensions to
which the TalkAnytime channels are connected. In either method, it is important to prevent unwanted access to the
PSTN and especially toll calling through the PBX.
