Question on ISDN LINK

Hi Tung,

You should be able to receive Audio call .

"but it can't pick up the incoming call from phone via the ISDN number" - Make unit in auto answer and see are you able to receive it ?

If you still face the issue then it may be issue with cofig or Isdn lines .

Question on ISDN LINK

Hi

This log shows you are dialing 4 digit number 8100 . Generally PSTN numbers are having minimum 6 digits .

xHistory CallLogs Call 39 RemoteNumber: "h320:8100;x-h320tlph=true"

Can you please confirm 8100 is correct number what you are dialing ?

If Yes then ,

h xHistory CallLogs Call 39 DisconnectCauseValue: 2

*h xHistory CallLogs Call 39 DisconnectCause: "Temporarily Unavailable"

*h xHistory CallLogs Call 39 DisconnectCauseType: RemoteDisconnect

this shows issue either with far end or service provider .

Can you please check with service provider .

Re: Question on ISDN LINK

Dear Dharmmesh

We have our own PSTN (ISDN BRI- Euro type) system.

It works for ISDNvideo call.

We can make ISDN video call via 8100.

But for audio-only call. got disconnect as the log show.

We use to have a edge 95, with the system PSTN systm it able to make ISDN, video call, and audio only call.

It there log I can get will show more detail?

Here is my ISDN LINK configuration.

the system I am using is C60 with ISDN LINK and SX20 with ISDN Link

Our PSTN system works fine with edge95 with audio only call.

Or is ISDN-LINK does not support audio-only call?

Thank you
