OICE OOPBACK
A loopback account is an internal account that creates a Realtime Transport Protocol (RTP) loopback.
Loopback calls allow you to actively troubleshoot voice issues. Loopback calls can be originated from the
command line interface (CLI), or the configured loopback extension can automatically answer an
incoming call. During the loopback call, you hear a mirror copy of the transmitted audio path. The
loopback call gives you the ability to verify two-way audio, test latency, and judge call quality. Unlike
normal calls between two endpoints, statistics are not recorded on loopback calls. Since the audio in the
call is simply a retransmission of the RTP stream, the call is not handled by digital signal processor (DSP)
so information on packet loss, delay, and jitter are not available on loopback calls.
In order to place loopback calls, you will need to configure a loopback extension. This is a special type of
user account that the AOS unit will use to place and/or receive the actual loopback call. A loopback
extension has the same basic configurable options that affect call quality as a normal user account.
Loopback accounts also require the same configuration that any other user account would need in order to
properly interact with the Session Initiation Protocol (SIP) server, SIP identity, external caller ID override,
etc. A dial plan must also be configured for the loopback account. The dial plan is needed for the unit to
accept and route the call. The commands in this section are used for creating and configuring a loopback
account. For additional information about configuring loopback accounts, refer to the Using the AOS
Loopback Account common application guide (article number 2363) available online at
https://supportforums.adtran.com.
To create a loopback account and enter the Voice Loopback Account Configuration mode, enter the voice
loopback command at the Global Configuration mode prompt. For example:
>enable
#configure terminal
(config)#voice loopback 5555
(config-LB-5555)#
The following commands are common to multiple command sets and are covered in a centralized section
