星号修改头文件

Question

我想替换星号的SPA2102。如何修改标题，如From, To和Contact?我需要替换标题，比如

From: "asterisk" <sip:[e-mail].6>;tag=as1ea48bca

到标头，如SPA2102。

我的SPA2102发送的是

"XXXX174264" <sip:[e-mail].6>

如何

我试着用SPA和Asterisk打电话。两者都注册成功。但是Asterisk不能打电话。下面是来自SPA的tcpdump:

Answer 1

尝试修改sip.conf:

[general]
realm=yourprovider-domain-here
useragent = Linksys/PAP2T-5.1.6(LS)
sdpsession= Linksys/PAP2T-5.1.6(LS)

Answer 2

您可以在dialplan中使用SipAddHeader，如

SipAddHeader(P-Preferred-Identity: <sip:XXXXXX@10.0.10.10>

Answer 3

有两个地方可以修改这些头信息。

在您的PBX中，对于PBX -> SPA意义上的呼叫，您应该这样修改您的sip.conf文件:

[general]
...
realm = my_realm.com ; This will substitute From: "asterisk"

在您的SPA2102中，对于SPA -> PBX意义下的呼叫，您必须进入SPA配置并更改用户信息。这是本指南的第5步:http://www.voipvoip.com/spa-2101/这里写着"显示名称"
