H.323/fax

[bb34nne]

Hello!

In my company we have two PBX, which are connected with each other over an IP trunk. Speech(voice) over IP trunk works normally, but the problem is when sending a fax over IP. It is probably necessary to activate QoS, but it costs money, and it does not come into consideration now. Sometimes sending a fax over IP works, but in most cases does not work.

Is it possible to adjust Network Delay or Network Jitter on PBX to get it working?

If anyone has experience with this type of problem? Information on the PBXs are below, and if you need more information, I will send them!

Thanks in advance

what you must do in the first place:

- upgrade the 2 PBX to SP7
- upgrade IPLU to latest version

if you can't upgrade to SP7, then at least put your IPLU's in R3C revision, R3A has "issues".
Also make sure that D1 of ICAT parameter of fax extension is 1, this will force 3,1 KHz (no interference of noise filtering)
