Question

当从手机拨打到SIP外线号码416XXXXXXX时，呼叫将直接转到Ext语音邮件，然后发送到电子邮件。通话记录显示以下内容：

[2015-06-02 13:52:49] WARNING[13331][C-00000003]: func_channel.c:538 func_channel_read: Unknown or unavailable item requested: 'reversecharge'
[2015-06-02 13:52:49] WARNING[13331][C-00000003]: app_dial.c:2437 dial_exec_full: Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)

即使SIP提供商编号似乎注册正常，看起来我的注册扩展名。如果SIP线路注册但扩展没有注册，是否有明显的原因？请帮忙！ THX！

查看sip调试的日志，看起来像是获取CHANNEL扩展注册的问题。

Answer 1

(cause 20 - Subscriber absent)

这意味着您尝试发送呼叫的SIP电话未连接到Asterisk PBX。很明显，因为你正在接听电话，所以后备箱工作正常。

请在此处发布手机配置，以便我们查看。同时发布结果：

sip show peers

...在PBX CLI。

当然可以！ /etc/asterisk/sip_additional.conf

为什么我的星号PBX没有注册扩展名，而是从sip.provider.ca注册sip行
