name = ('1' + name) if name =~ /^[2-9]\d{9,9}$/

req.Header.from.FromURI.User = name
req.Header.From.FromName = name
可能会有用，你试一下。

瞎蒙出来根据区号，选择性使用哪一 GV account。
但 CID 似乎还没弄出来。如果有大侠，能否帮忙搞定 CallerID，并检查一下语法. 多谢。
原问题和代码如下
==============================
用 SIPGate + GoogleVoice + SIPSorcery, 一直用 Simple Dial plan.
有哪位高人能发个具有如下功能的 Complex Dial plan 么？
1. 根据区号自动选择使用哪一 GV account.
本人有两个 GV account, 一个搬家前的区号，另一搬家后现在的区号。希望和老朋
友联系时用搬家前的号码。打现在本地时，使用新的号码。
2. 来电显示
现在来电显示在姓名处显示的是 SIPGate 的号码，在电话号码处显示的是对方真实号
码。希望能将 SIPGate 号码替换成对方实际姓名。
我知道网上的 Complex Dial plan 可以 Customize 实现上述功能。
想偷懒，如果谁有现成的直接能用最好。
另一方面也是实在忙得没空。

标 题: 自己换exhaust manifold靠谱么？
发信站: BBS 未名空间站 (Thu Apr 22 01:28:56 2010, 美东)
现在的这个header锈穿了，搞得发动机舱比平时热好多，担心那些电子部件和线路的寿
命，还有也怕哪天锈的厉害直接掉了（看到很多买的人都是因为这个原因）。
买了一个short header（http://www.americanmuscle.com/bbk-shorty-headers-9904v6.html），问了熟悉的garage，换要人工180刀，是不是比较贵了？自己搞这个麻烦么？他说要搞大半天，至少5个小时。

如果工具对的话很容易，不要拿“L"型的小铁棒整，用不上力。我的也是altima，整了
很多遍
了。
楼上的说道exhaust，那我也顺便插句。首先exhaust可分4部分：头段header；三元催
化剂CAT；
中段和尾端catback。
任何一部分都可在ebay单独买到，对于02altima，header的改装件（比原厂的性能更佳
）100-ish
就可以买到，CAT不晓得，catback顶端品牌500-ish刀，中端品牌200-ish刀，尾端
muffler几十
刀。labor fee：header和catback各需一个小时，按正规的小时计费100刀/H，可以自
己算下这个
exhaust的维修到底要多少钱。如果exhaust再发生问题，希望LZ能省点钱 |

发帖数: 7271 | 38 照我理解，以dll办法为例：
1. 所有找到的某个目录下的decoder dlls，加入链表；
2. 把header依次传给decoder的回调函数来分析header并返回是否接受；
3. 如果某一个decoder回调函数返回接受，就把数据传给该decoder的
decode回调函数；
分析header的回调函数是decoder来implement的。新decoder
的code当然需要编译成dll。除了这个，还有什么要重新编译的么？

Houston 报纸版面字数限制，我们还对一些文字进行了删减。这篇稿子基本是原文长度
的，当然进行了一系列的编辑。
我们还有 5 篇通稿，该交给谁联系一下？
另外不好意思的是，因为这些通稿以前是发给 Houston 报纸的，所以用的 header 是
Houston chapter 的。我这里也有 OCEF 总会 header 的，可能对国内发行更好。这个
是 OCEF 各地义工共同劳动成果，至少有 6 位参与写作 － 我 push 得也比较厉害，
汗一下。。。
再汗一个，header design 的很简单。。。 |
