Re: [SR-Users] how to match exact string value in mtree (Uri Shacked)

Hi Maybe I didn't understand your scenario, but I don't see how to do it with the dialplan module. Let's say you have two entries in your dialplan table: 09555333 (this should go first) 09555* If your string is 09555444 you will still get the second entry....
