Matrix SETU ATA211 SIP-FXS-FXO User Manual

50 Matrix SETU ATA211 V1 System Manual
For e.g. consider the following scenario: (In this figure, ATA is referred as ATA211)
• Customer has multiple offices across the globe which he wants to connect over IP network for voice
calling. But existing voice infrastructure which includes PCM/TDM PBX does not support VoIP connectivity.
To integrate VoIP functionality in existing voice infrastructure, customer installs ATA211 as shown in the
figure with existing PCM/TDM PBX.
• Customer has installed IPPBX on public IP network to which all ATA211 are registered. This is to take care
of NAT traversal and for easy maintenance.
• Now the voice communication over IP between the offices takes place as follows:
• If PBX1 extension 101 wants to connect to extension 102 of PBX2, caller first dials 22 (22 is the SIP-ID
assigned to ATA2 where caller wants to reach) with some trunk access code. The PBX1 routes this call
to its FXO port which is connected to the FXS port of ATA1.
• ATA1 then routes this call to IPPBX which is again routed by IPPBX to ATA2.
• ATA2 places the incoming call to its FXS port as per incoming call logic.
• When PBX2 receives the incoming call, Auto-Attendant or DID answers the call on its FXO port and
play dial message/dial tone. Caller then dials the desired called party number viz. 102. PBX places the
call to its extension viz. 102.
• To achieve the above calling methods between office sites, caller needs to dial the number in two stages
each time to reach the extension of other office. In first stage, caller first dials the SIP-ID of ATA which is
followed by the number of extension to be called in second stage.
• However, in the real scenarios, caller only wants to dial the complete number viz. SIP-ID of ATA and called
extension in one stage instead in two stages.
