In the previous article, we briefly introduced the IP telephone services of Cisco's Unified Communication System. Here, we want to give you a comprehensive understanding of this system, we will continue to introduce other parts. First, let's review the summary mentioned above.
Cisco Unified Communication System
We have previously introduced the overall structure of Cisco's Unified Communication call system. Now let's take a look at the core features of SIP implementation and other supported functions. We hope that the introduction and analysis in this article will help you understand this part of knowledge.
Cisco deploys SIP based on RFC to implement core telephone features. To provide many SCCP-based features,
that session is closed, the serial console session becomes trace Channel. The next Telnet console session that is the Access console is then the trace Channel.
The debug command is shared between all Telnet and serial console sessions.Note the disadvantage of the Trace channel feature is that if one administrator is using the serial console and another administrator initiates a telnet console session, the debug command output on the serial console will stop without warning. In addition, the Adm
