Abstract

Many users of the DirectTalk* voice response product have problems configuring their setup to match that of the telephony switch which they are connecting to. This solution attempts to address that problem by suggesting a method by which the two products can communicate to establish settings. Switches are currently connected to DirectTalk via Digital Telephony trunks, and also via ACL links, which usually take the form of a serial line or ethernet connection. The ACL connection allows the systems to send extra information to each other over and above the voice information being sent down the telephony trunks. This solution is to use these ACL (or sometimes called EDL) links to enable the products to converse and allow one another to be auto-configured. DirectTalk could be sent the information from the switch saying what country, E1/T1, ISDN/CAS, and more detailed information to do with signalling and capabilites for transferrring calls. It could even go so far as to include handshaking as in modems to set a mutally agreeable protocol that supports the best functionality from both ends when both ends support a wide range of diverse protocols and sometimes converters between protocols.
