callmaxwait: max waittime allowed for operators between calls (for administrative purposes)enforcestrongauth: enforce authorization and strong passwordsTry to avoid prioritizations by users, gateways, simpackets or channels (absolutepriority, priority, allowedpartners, prioritypartners, etc)Almost all kind of configuration can be set up by using only the “routing” form.4.4. Routing4.4.1. Dial patternsThe “dial patterns” terminology is not used with the mizu voip server. You can apply the number rewrite rules by the following ways (startingfrom simple to more complex rewrite rules)1. Number normalization: Opent the “Configurations” form and search for the “normalize” string to list all related settings.2. These settings can be used for basic number “normalization” to remove strange characters (like new line) and to remove IEC code. Bydefault this is set to remove the common international escape codes (00,+). To turn this off, change the followings:a) set cfg_normalizenumbers below 3 (2 should be good)b) set normalize_localpx to 0c) set “normalize_clean“ value below 4 (3 should be fine)3. Tech prefix: tech prefix related operation should be done by using the “techprefix” box in the “Users and devices” form. Set this for the“SIP servers” where a specified tech prefix needs to be sent or set it for the “Traffic sender” when you receive the traffic with atechprefix from some routes.4. Prefix rules: this is used for simple prefix add/remove operations. (discussed below)5. Dial plans: you should use this option if you need full control4.4.2. FirewallThe firewall rules are checked first when a call is initiated (SETUP or INVITE received), so this is the most effective way to block some unwanted trafficsender.All ip address are allowed except those are listed if the ip with ‘*’ is 1.Otherwise (if the ip ‘*’ is set to 0) all address are blocked except those that are listed here.
