When configuring the remote units for 2:1 operation, you need to set the Remote Number and 
Gateway Port Offset parameters correctly. 
 
For example, if you are using two 8-user remotes, PBXgateway ports 1 through 8 will be for the 
first unit, and ports 9 through 16 will be for the second remote.   
 
1.  When configuring the first remote unit, set the Remote Number parameter to 1. 
2.  When configuring the second remote unit, set the Remote Number parameter to 2, and set 

the Gateway Port Offset parameter to 8.  
 
Path: Remote ->Configuration -> Connect -> Gateway Port Offset 

 

3.  After rebooting the units, ports 9 through 16 from the PBXgateway will be assigned to the 

second remote unit. 

4.  Set the Port Compression for WAN 1 and WAN 2 to provide adequate bandwidth for the 

phones extended off of each remote. Default setting ADPCM32.  
Gateway ->Port->Default->Voice 

The best voice quality is achieved by using the ADPCM 32 compression.  The maximum quality 
comes at the expense of the highest utilized bandwidth.  The largest voice compression is 
achieved by using G.729A.  If you are using this algorithm, you will save on bandwidth and still 
achieve voice quality that is regarded as near toll.  If absolute conversation quality is your focus 
and bandwidth is no object, you probably want to select ADPCM 32.  If bandwidth is a priority you 
will employ G.729A.  
 
The compression for both WAN ports does not have to be the same. WAN1 may have 4 phones 
extended, while WAN2 may have 8. Set the Method (Compression) for each port, or use the 
default port menu. 
If you are using different compression algorithms for each individual user (port), use the following 
formula to establish your aggregate data bandwidth needs. 

A  x 16   + B  x 32   + C  x 40   = D 
 
A: number of G.729A Users 
B: number of ADPCM 24 Users 

 

C: number of ADPCM 32 Users 

 

D: Total Bandwidth
