Abstract

This invention provides a method and apparatus for, incorporation, with a non-modifiable legacy IP telephony call control system, of additional language character support, that further, does not compromise the maturity of the call control system. A system according to the present invention comprises (A) a legacy call control system for receiving incoming events and legacy strings and, in response, outputing resulting events and said legacy strings; and (B) an adapter for, (i) receiving said incoming events and alternate strings, (ii) generating said legacy strings corresponding to said alternate strings, (iii) passing said incoming events and said corresponding legacy strings to said legacy call control system, (iv) receiving from said legacy call control system said resulting events and said corresponding legacy strings, (v) identifying said alternate strings using said received corresponding legacy strings and (vi) outputing said resulting events and said alternate strings.

Claims

1. All control system for incorporation in an IP telephony switch, said system comprising:

a legacy call control system for receiving incoming events and

legacy strings and, in response, outputing resulting events and said legacy strings; and

an adapter for, (i) receiving said incoming events and alternate strings, (ii) generating said legacy strings corresponding to said alternate strings, (iii) passing said incoming events and said corresponding legacy strings to said legacy call control system, (iv) receiving from said legacy call control system said resulting events and said corresponding legacy strings, (v) identifying said alternate strings using said received corresponding legacy strings and (vi) outputing said resulting events and said alternate strings.

2. The system of claim 1 wherein said adapter additionally stores pairs of said alternate strings and said corresponding legacy strings, for use in identifying said alternate strings.

3. The system of claim 2 wherein said adapter comprises a memory for storing said stored pairs.

4. The system of claim 1, wherein said adapter comprises:

an input adapter for (i) said receiving of said incoming events and alternate strings, (ii) said generating of said legacy strings, and (iii) said passing of said incoming events and said corresponding legacy strings to said legacy call control system; and

an output adapter for (iv) said receiving of said resulting events and said corresponding legacy strings, (v), said identifying of said alternate strings, and (vi), said outputing of said resulting events and said alternate strings.

5. The system of claim 3 wherein said IP telephony switch includes:

an IP telephony application,

a device control,

a switch management system,

and a trunk,

and wherein said adapter further comprises a plurality of clients for cooperating with said IP telephony application, said device control, said switch management system, and said trunk.

7. The system of claim 2, wherein said adapter comprises:

an input adapter for (i) said receiving of said incoming events and alternate strings, (ii) said generating of said legacy strings, and (iii) said passing of said incoming events and said corresponding legacy strings to said legacy call control system; and

an output adapter for (iv) said receiving of said resulting events and said corresponding legacy strings, (v), said identifying of said alternate strings, and (vi), said outputing of said resulting events and said alternate strings.

8. The system of claim 3, wherein said adapter comprises:

an input adapter for (i) said receiving of said incoming events and alternate strings, (ii) said generating of said legacy strings, and (iii) said passing of said incoming events and said corresponding legacy strings to said legacy call control system; and

an output adapter for (iv) said receiving of said resulting events and said corresponding legacy strings, (v), said identifying of said alternate strings, and (vi), said outputing of said resulting events and said alternate strings.

6. A method of adapting a legacy call control system for inputing incoming events and legacy strings and, in response, outputing resulting events and said legacy strings, said method comprising:

i) inputing said incoming events and alternate strings into an adapter,

ii) withen said adapter generating said legacy strings, corresponding to said alternate strings,

iii) withen said adapter passing said incoming events and said corresponding legacy strings from said adapter to said legacy call control system,

iv) withen said adapter receiving, from said legacy call control system, said resulting events and said corresponding legacy strings,

v) withen said adapter identifying said alternate strings using said corresponding legacy strings received in step iv), and

vi) withen said adapter outputing said resulting events and said alternate strings.
