请教一个Cisco outbound的问题

基于IVR campaign 模式的外呼。sipdialer中的虚拟端口向外部拨号时,经过网关发送sip邀请时,网关回给sipdialer一个503 service unavailable的错误,有人清楚为什么吗?
下面附上网关debug ccsip message的信息

不清楚是否需要做dialpeer进行匹配
对于IVR模式的外呼的流程不是特别清晰,有知道的可以介绍一下吗?官方文档表达的不太明白

有关SIP dialer IVR campaign的call flow可以参考附件19页。

1.Textfile doesn’t have to be placed on the logger. A network drive can be mapped tothe logger and the import process can read the file. Need to make sure that the file name iscorrect, however, otherwise the import proc

2.Import process will put the records inthe DB based on the rules created for the campaign.

3.When a campaign is active the dialer willrequest records. The number of recordsrequested is defined in the skill group configuration for the campaign. (See p. 135 of the 8.5(1) outbound guide.)

4.Dialer tells the GW to place the call

5.GW dials the customer and connects

6.CPA is performed to determine live voiceor AM. RP call is transferred to maydiffer based on result.

7.IVR location requested.

8.MR PG makes rout request.

9.Route is returned.

10.Dialer receives the number.

11.Dialer tells GW to transfer to IVR.

12.Call is transferred via UCM

网关应该已经有Dialpeer配置了, 否则应该是404, 估计是和下一跳某些参数协商有问题。 可以再看一下SDP部分。
