there is a system of multiple SoundStructure devices, each SoundStructure device can have a
SoundStructure VoIP Interface installed.
SoundStructure VoIP Interface Plug-In Card
The SoundStructure VoIP Interface has the following capabilities:
● 12-line support where any single call or a conference of calls can be sent to the SoundStructure
device.
● 24 call appearances where any call appearance or conference of call appearances can be sent to the
SoundStructure device.
● Supports the following narrowband audio codecs:
 G.711 m/A,
 G.729A (Annex B),
● Supports the following wide-band audio codecs:
 G.722 (7 kHz),
 G.722.1 (7 kHz),
 G.722.1C (14 kHz)
● Supports SIP signaling and many SIP call features.
● Compatible with many SIP call management platforms.
● Supports API command set for dialing, on hook, offhook, call hold, call resume, call transfer, call blind
transfer, call forward, call hangup, call conference, call split, call join, and do not disturb.
● Easy to upgrade from an existing SoundStructure TEL1 or TEL2 system.
SoundStructure TEL1/TEL2 to SoundStructure VoIP Interface Considerations
To better understand how the SoundStructure VoIP Interface relates to a TEL1 and TEL2 interface card,
consider the following points:
● One SoundStructure VoIP Interface may be used per SoundStructure device, just like a TEL1 or a
TEL2 interface card.
● A SoundStructure VoIP Interface works like the TEL1 interface and supports one independent
telephone call to the SoundStructure system. Just like the TEL1, one independent call is sent to the
SoundStructure audio matrix. However, this one independent call can be the mix of two remote
participants. See the command examples at the end of this chapter for more information on dialing
two remote participants.
● Support for 12 "lines" means that 12 different extensions can be defined for this card to provide
different dial-in numbers for remote participants if necessary.
