Hey,<br><br>Hope someone can help me. I have a GSM Gateway attached to my 1760 router via a VIC2-FXO. The sim card which is installed in the GSM Gateway is an O2 Simplicity Sim (Unlimited calls to same Cellular Provider). Now O2 operates a multitude of dialing prefixes for their mobile phones and at present I have cut down some of the work to reduce the long list down to their main components. <br>
<br>Example - Previously where I would had destination-patterns for 07510, 07511 all the way to 07519 that has been replaced with - destination-pattern 0751[0-9]T<br><br>However, I have only managed to whittle the 86 dial prefixes down to 34 (with the new destination-pattern's)<br>
<br>What is the procedure for nesting if it can be done to further reduce the destination-patterns. Can there be multiple instances of [ ] ie<br><br>Based on the following 3 prefixes - 07858, 07860 & 07864<br><br>Could I do destination-pattern 078[5,6][0,4,8]T<br>
<br>If there are any better suggestions, by all means say.<br><br>Help appreciated.<br>
