Q2：如何与NX进行媒体数据包【RTP Package】的交互？
A2：NX对于媒体数据包来源不做验证。如UAC本地对于UAS的媒体来源有要求，为避免因媒体IP加白问题导致媒体无声，请对以下媒体IP和Port Range进行整体加白。传输协议为UDP、RTP。
| 区域范围 | 媒体IP | Port Range |
| 中国·香港 | 34.150.77.162 | 10000-19999 |

Q3：NX的DID产品，呼叫格式是怎么样的？
A3：呼出【客户—>NX PBX】
主叫：DID号码【CountryCode&Local Number，E.164不带‘+’号】，例如：85238531141
被叫：默认为仅支持呼出DID所在国家的号码【CountryCode&Local Number，E.164不带‘+’号】，例如：85296844123。如果特殊需要需支持外呼非本地，可以订阅号码前期与NX商务同事具体说明，将会提供对应的协助。注：支持外呼非本地，并非等用于支持呼出全球，具体支持的国家清单以实际的资源性能为准。
--------------------------------------------------------------------------------------------------------------------------------------
呼入【NX PBX—>客户】
主叫：NX将会透传运营商提供的原始主叫
被叫：DID号码【CountryCode&Local Number，E.164不带‘+’号】，例如：85238531141
Q4：呼出【客户—>NX PBX】出现了失败，可能是哪些原因导致的？
A4：1. 主/被叫号码未正确使用CountryCode&Local Number。
2. 被叫号码所属国家地区不在开通的业务范围之内，此类情况通常会返回Code404。
3. 呼出实时并发，超过了订阅并发，此类情况通常会返回Code480。
4. 呼出源IP地址，不在已加白IP清单范围内，此时可以参考网关配置流程进行添加，此类情况下，NX PBX不会回应invite请求，可能造成UAC端显示呼叫超时。
5. 被叫号码自身为不活跃号码，此类情况可能返回Code400/480/484/486/500/503/603等。
6. 账户余额不足，DID号码配置被系统自动锁定，此类情况通常会返回Code480。
Q5：呼入【NX PBX—>客户】出现失败，可能是哪些原因导致的？
A5：1. 存在跨国呼叫的情况，主叫所在运营商无法触达DID号码。
2. DID号码的实时呼入并发超过订阅的并发，此类情况可以登录客户端，前往DID号码模块检索呼叫记录来判断，对应的会 有显示无可用路由。
3. DID号码出现故障，如果持续的呼入不成功，可以反馈到NX客户支持团队进行进一步排查。我们的邮箱地址为noc@nxcloud.com。
Q6：网关活跃度options消息探测失败？
A6：此问题的原因，一般是源IP地址，不在已加白IP清单范围内，此时可以参考网关配置流程进行添加。
Q7：如何退订DID号码？
A8：如需退订号码，可登录NX客户端后，在DID号码模块进行退订，具体路径：DID号码——我的号码——停用【需在停用位置操作两次】
Q9：订阅DID号码，如何续费？
A9：所有号码初次订阅第一周期到期之后，后续默认按月续费。系统将会在次月1号凌晨发起扣费，如果扣费失败将会暂时停用号码服务。如果当月7号仍未续费成功，则会在8号凌晨终止号码的使用且无法通过充值账户余额来恢复号码。
