Problem on connecting VG6100 to PBX

[Wtech]

Hi,

I found 2 problem on connecting VG6100 (E1) to PBX acatel

   1. The sound is very bad, (not clear, very noisy), Is there any parameter to adjust

   2. There is 2 site connect like this

                  PBX A --- E1 ---  VG61000 ------  Network ------ VG6100 ----E1 ---- PBX B

          - PBX A can call to PBX B but PBX B cannot call to PBX A, here is the log on the VG6100 connected PBX B

1d:0h:56m:8s (   lgr_psbrdif)(1074      )  #41:ActivateChannel:RtpPayload: -1

1d:0h:56m:8s (   lgr_stk_ses)(1075      )  <SESSION #49> SendToCall - event: CONNECT_EV  m_Call = 105319980

This is probably your PRI TDM BUS setting Alaw/Ulaw this will give you very noisy line.

That's definately the first thing I'd look at. Remember that the TDM codec setting is related to the line, not the codec in use at the handsets. This can be confusing in Europe (and Japan etc), as the VCX itself does not support alaw, but the TDM bus setting MUST be set to alaw. In the US both the TDM codec and the phones themselves would be using ulaw.

On our gateways I also usually remove G729 as an option.
