摘要： A voice gateway receives packets transmitting voice data between two voice gateways, each received packet includes header data and voice media payload, means for establishing a voice trunk between the two voice gateways based on the header data of the received packets. The voice media payloads of the received packets are extracted and combined into a single packet, the single packet including for a voice call a dedicated channel data of the established voice trunk comprising an identifier of the respective voice call and the voice media payload of the respective voice call. A single set of header data is added to the single packet, the single set of header data includes base information for synchronizing the flow of data between the two voice gateways. The single packet is transmitted to the receiving voice gateway via the voice trunk.
摘要翻译：语音网关接收在两个语音网关之间发送语音数据的分组，每个接收的分组包括报头数据和语音媒体有效载荷，用于根据所接收分组的报头数据在两个语音网关之间建立语音中继的装置。接收到的分组的语音媒体有效载荷被提取并组合成单个分组，单个分组包括用于语音呼叫建立的语音中继的专用信道数据，其包括相应语音呼叫的标识符和相应的语音媒体有效载荷语音通话。单个报头数据集合被添加到单个分组中，单个报头数据集合包括用于同步两个语音网关之间的数据流的基本信息。单个分组经由语音中继发送到接收语音网关。

摘要： A method for supporting non-secure warning tones on packet-switched networks involves receiving a call attempt from a source phone to a destination phone, checking if a connection of the security domains of the source phone and the destination phone via a MLS voice gateway is allowed, and checking if a generation of a non-secure warning tone locally by the source phone is required. A call is established from the source phone to the destination phone upon acknowledgement of the local generation of the non-secure warning tone by the source phone.

摘要翻译：一种用于在分组交换网络上支持非安全警告音的方法包括从源电话接收到目的地电话的呼叫尝试，检查源手机和目的地电话的安全域经由MLS语音网关的连接是否是允许，并检查源手机本地是否产生不安全的警告音。在通过源电话确认本地生成非安全警告音时，从源电话到目的地电话建立呼叫。
