This is probably a good place to park this information on how call routes work, just for clarification. I hope it's of use.
For each Trunk (SP, LI, PP, BT etc), configure routing rules for incoming calls in the following format:
rule or {rule},{rule},...., where:• Rules and peerings are tested from left to right
• The first matched rule will be selected and used to route the call
• Every rule must be placed inside a pair of { } curly brackets
• Digitmaps always inside round brackets (Mabc)
• If there is only 1 rule, then { } is optional.
• {0255556666:SP2} is the same as {(0255556666):SP2} - since 0255556666 is just a constant, the parentheses are optional - however:
• If the rule includes things like xxxx and so forth that is a part of digitmap syntax, the round brackets are required, like this: {(025xx.):SP2} or {(xxx|123|(MMMM)):}
