它的具体流程是这样:
1. Physical Interfaces -- Phone1 Port -- DigitMap:对拨的号码进行一遍预处理。033-86-xx.的处理结果还是033-86-xx.
2. Physical Interfaces -- Phone1 Port -- OutboundCallRoute:拨出路由选路。 {(Mtg1):tg1}会被命中,这样就选中了Trunk Group1
3. Trunk Group1的Member只有一个SP2,它就由SP2拨出了,而拨出的号码还是033-86-xx.
4. voip.ms收到033-86-xx.会选Value是因为这是voip.ms的定义。参见这页:

Prefixes for International calls are
00 and
011, however, remember you can still use
033 for Value and
044 for Premium. These codes work as an override to the setting from the portal, so you can place a single call using one route, without having to change the settings.
