Closed. This question is off-topic. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it's on-topic for Stack Overflow. I want to configure Kamailio server so that traffic will be forwarded to other four asterisk servers equally. It is working fine with a single asterisk box but I am unable to forward a call to another asterisk box. Here is the kamailio.cfg that I am using. #!KAMAILIO #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT #!define WITH_ASTERISK # *** Value defines - IDs used later in config #

GSMA RCS架构

由开放移动联盟(OMA)和GSM协会(GSMA)等主要标准组织制定的消息传送技术在架构和技术细节方面有许多相似之处。 OMA融合IP消息系统(CPM)从一开始就基于OMA SIMPLE IM进行设计. 因此重用了其大部分有关即时消息功能的详细技术。 GSMA丰富通信套件(RCS)在其早期版本中采用了OMA SIMPLE IM架构. 并且最近采用了OMA CPM架构来提供融合通信服务功能。 因此. RCS由许多具有最先进的服务特性. 协议和接口的功能组件组成. 本文将对此进行简要回顾。 GSMA富通信套件(RCS)最初基于OMA SIMPLE IM架构. 但采用了RCS r4.0的OMA融合IP消息系统(CPM)架构。 虽然RCS r4.0更新至RCS 5.0及以上版本. 但整合了更多的服务特性和更详细的技术要点. 但其架构本身保持不变。 SIMPLE IM和CPM之间的概念区别在于SIMPLE IM专注于在SIP / IP核心上实现IP消息传递功能. 而CPM侧重于如何实现不同通信技术中的融合用户体验. 例如IP消息传递 . 语音. 视频等。在CPM架构之上. RCS已经指定了内容共享. 位置信息共享和社交呈现信息共享等附加增值服务功能. 反映了近期许多社交网络服务已经证明的市场需求。 SIMPLE IM启动器由IM客户端,IM服务器和IM XML文档管理服务器(XDMS)组成。

《FreeSWITCH: VoIP实战》:SIP 模块

谁说我不能喝 提交于 2019-12-02 21:00:39
SIP 模块是 FreeSWITCH 的主要模块,所以,值得拿出专门一章来讲解。   在前几章时里,你肯定见过几次 sofia 这个词,只是或许还不知道是什么意思。是这样的,Sofia-SIP 是由诺基亚公司开发的 SIP 协议栈,它以开源的许可证 LGPL 发布,为了避免重复发明轮子,FreeSWITCH 便直接使用了它。   在 FreeSWITCH 中,实现一些互联协议接口的模块称为 Endpoint。FreeSWITH 支持很多的 Endpoint, 如 SIP、H232等。那么实现 SIP 的模块为什么不支持叫 mod_sip呢?这是由于 FreeSWITCH 的 Endpoint 是一个抽象的概念,你可以用任何的技术来实现。实际上 mod_sofia 只是对 Sofia-SIP 库的一个粘合和封装。除 Sofia-SIP 外,还有很多开源的 SIP 协议栈,如 pjsip、osip 等。最初选型的时候,FreeSWITCH 的开发团队也对比过许多不同的 SIP 协议栈,最终选用了 Sofia-SIP。FreeSWITCH 是一个高度模块化的结构,如果你不喜欢,可以自己实现 mod_pjsip 或 mod_osip 等,它们是互不影响的。这也正是 FreeSWITCH 架构设计的精巧之处。   Sofia-SIP 遵循 RFC3261 标准,因而 FreeSWITCH

Android video calls using android's sip

[亡魂溺海] 提交于 2019-12-02 20:52:19
I want to develop a program for a video calls in android. I thought of using the built in sip that introduced in android 2.3.3. But how can I initiate the video calls? I see that it is not supported. TryTryAgain I believe the generic Android SIP stack supports video. Taken from: https://developer.android.com/reference/android/net/sip/package-summary.html If you want to create generic SIP connections (such as for video calls or other), you can create a SIP connection from the SipManager , using open() . If you only want to create audio SIP calls, though, you should use the SipAudioCall class,
