Note: When answering multiple SIP connections, answer routes can be used to create deterministic
dialing, which routes audio from incoming calls consistently to the same inputs and outputs. For
more information please see
ID, dial routes and G3 profile information can not be used for SIP connections because Tieline
session data is replaced by SDP for SIP connections.
2. Continue through the wizard and configure the second dial and answer stream connections in a
similar way to the first audio stream connections. Then click Save Program to save all settings
and click Finish to exit the Program Manager wizard. The newly created program will be
displayed in the left pane within the Program Manager panel and in the Program Loader
panel.

Answering Multiple SIP Calls
To answer multiple SIP calls you need to create and
program in the codec, or it will be unloaded by the first SIP call and a default peer-to-peer program
will be loaded.
Important Note: Remember to lock an answering program in a codec when answering
multiple SIP calls.

Answering Multiple SIP Peer-to-Peer Calls
The codec is capable of accepting multiple SIP Peer-to-Peer connections and routing them in a
deterministic manner to specific audio input and outputs.
Tieline session data, in conjunction with unique audio ports, normally facilitates routing of multiple
incoming streams to specific inputs and outputs on a single answering codec. Session Description
Protocol (SDP) is used over SIP instead of Tieline session data, therefore deterministic routing of
incoming calls needs to be done a bit differently. There are two options:
1. SIP Accounts: Using the SIP Accounts panel in the HTML5 Toolbox web-GUI, register up
to 6 SIP accounts and configure a unique answer Route in each SIP account. Then create a
multiple stream answering program (e.g. 2 x Mono Peer-to-Peer) and configure an answer
