The minimum number of UDP ports to open depending on the PBX model:
Model | Calls | Ports |
WGW08 | 4 | 572 |
WGW16 | 8 | 687 |
WGW40 | 15 | 1287 |
WGW90 | 30 | 1716 |
WGW250 | 120 | 3432 |
WGW500 | 150 | 4290 |
WGW1000 | 300 | 8590 |
WGW5000 | 600 | 17160 |
The formula is the following one: “(M x Number of calls) + 10%”, where M is:
130 for PBX supporting up to 7 concurrent calls
78 for PBX supporting up to 23 concurrent calls
50 for PBX supporting up to 45 concurrent calls
26 for PBX supporting more than 45 concurrent calls
