Emergency response is a matter for all operation and maintenance engineers have to face, whenever there has been a major service failure, the person in charge needs to be able to respond immediately and organize team members to quickly restore service, at this time, operation and maintenance team once contact less than that in terms of the service is disastrous, and for the operation and maintenance team is concerned, it completely lost the trust of the people.

Therefore, to achieve real-time telephone response, it is a very important thing. There will be such a point of view, as long as I have enough sense of responsibility, they will not miss calls, in fact not the case, responsibility is important, but if there is no good way, even if done, as well as luck, this Wu Jun Silicon Valley letters from the difference between professional and business, have made it very clear. Therefore, today I share with you and the next is how to do

To do not miss a call, you first need to know enough about the phone, and then targeted responses

You can hear information about the calls and the following:

• Operators

• Signal quality

• Prepaid Tracker

• remaining battery

• Silent shock

• Ringtones size

• Software Settings

• Phone hardware

• Whether carry mobile phones
  
  to tease out the factors mentioned above, it will be more clear how to solve

• Operator: Select the local network coverage is good , I am using a telecommunications, telecommunications because there are only a cell signal

  • Pit 1: Dual SIM mobile phone is one solution, but in general the company's system does not support multiple phone numbers, and therefore need to ensure that all relevant personnel know that you have two phone numbers is also a cost, I do not recommend
  • Pit 2: Dual card mobile phone + unresponsive call forwarding, one solution is better than the previous, but the need to consider the cross-way call transfer operators and unresponsive on a reasonable set of circumstances, this time, be careful insufficient number of phone calls two problem because during the call forwarding, two numbers will be charged, but the average person calls to alternate phone numbers will not give a good redundancy

• 话费余额：建议选择各类APP的定期缴费 ，且缴费金额一定要高于月租一个档次，缴费时间要设置在每月扣月租前几天缴费 ，有些运营商提供余额预警也可以用上，但不要完全依赖于他，同时每年预充500元兜底

  • 坑1：每月10号充值，每月1号扣费，然后有一次1号费用不够就停机了
  • 坑2：每月定期缴费功能异常，没有缴费

• 剩余电量：确保下午六点前手机电量至少50%

  • 坑1：六点前手机快没电了，结果有聚餐活动
  • 坑2：六点前手机快没电了，结果出门堵车堵死了，或者有其他突发事件
  • 坑3：不要乱装APP，不要让APP在后台运行，把电给耗没了
  • 坑4：不要玩手机，电量损耗会非常严重，很难让你顺利回家

• 静音震动：将手机常态下设置为铃声+震动，确保静音模式下一定会震动即可

  • apple watch ：这是一个很好的解法，基本上带上apple watch后，漏接的概率会大幅降低，等到apple watch3在国内支持打电话之后，游泳都可以放心大胆的玩了

• 铃声大小：一般来讲建议是铃声越大越好，不好设置较大声音的地方，靠震动来解决

  • 家里有小孩，完善休息，如果长期Oncall，肯定不适合太大铃声，那把手机放枕头下靠震动搞定

• 软件设置：一旦设置好，做一次手机备份需要的时候快速恢复，不要把手机给小孩玩

  • 坑1：婴儿玩手机，口水把手机充电口，听筒搞坏了
  • 坑2：儿童玩手机，把你手机设置修改的面目全非，你却浑然不知
  • 坑3：给你来一个飞行模式或者关闭某些项，通话功能无法使用了

• 手机硬件：每年更换新手机 ，尽量换好点的手机

  • 坑1：铃声+震动的模式，常态下报警短信较多，时间长了，手机就容易坏，高峰时候，半年换一个手机，所以每次手机都舍不得买太贵的，然后形成恶性循环，最后，换了iphone，这种情况缓解很多
  • 坑2：iphone爆出了通过判断电池新旧来进行手机CPU降频，手机慢容易死机，有个紧急电话你接不起来，估计想死的心都有了

• 手机是否随身携带：这个真心要养成习惯，就放裤兜 ，不然谁也救不了你

• 信号质量：短时间的无信号可以用来电提醒来补充，长时间的无信号一般都是犄角旮旯的地方，或者是地下室或者车库之类的，需要尽量避免去这类地方

  • 坑1：聚餐选了一个很有特色的地方，特色到了连信号都没有，那这顿饭吃的就没那么踏实了，要尽量避免，一般连锁类品牌或者不错的地方，信号都不会有问题，主要是小地方，需要注意
    上述的解决方案，主要是针对应急响应，如何不漏接电话，如果大家的主要苦恼是报警短信/电话太多，那么可以参考上述的方式，但正道是要快速降低报警量。

上面的各种坑，也是我自己这么多年运维工作，一个个踩过的，所幸很多情况没有被人发现，所以现在也可以和大家吹牛说如何确保不漏接电话。但挂万漏一，之前我的经理电话我的时候，因为月初扣费导致停机无法接听，所幸平时口碑不错，没有给老板留下不好的映像。但如果是新老板第一次联系你呢？呵呵

上述的一些经验，执行下来，你就会看到这样一个形象：每年换新手机和watch，还全是apple的，吃饭聚餐从来不爱去犄角旮旯特讲究排场，话费余额至少300+，聚会时总会看看有没有信号和来电，没电了立即把别人的充电宝抢过来充电，好像生怕错过了上亿的生意，活生生一个“土豪”，但这个“土豪”容易吗，哈哈！
