Incoming FAX-Traffic Rerouting

[MD110Tech]

Hello @ll!

I just stumbled across this very interesting forum and thought I'd register. I'm from Austria and am employed at the main Ericsson Partner and reseller in Austria as an on site technican.


And here goes my first question

We often have the problem of FAX calls that are rerouted to the operator because eg. the FAX-Server, that is connected over TLU79 or TLU76 to the MD is down (MRS, Ferrari, etc.)
Is there a possibility to stop the MD from rerouting FAX calls?
AFAIK there are only 2 possibilitys:
1 would be to set D1 in SEL to 0 on the incoming PSTN-route, but this would also affect normal speech traffic so it is not an option.
2 would be a internal QSIG (or whatever) and the FAXes routed over this tieline. Then I am able to set SEL to 0xxxx.
But if this tieline is busy, the whole rerouting issue starts again.

A third option would of course be to tell the customer to get a new number and line from the PSTN and use it only for FAX traffic, but which customer would do this???

Do you have any ideas what else could be done about this problem?


Thanks alot!

You can use a generic extension and a PN list on this. We use this and when the fax server is unavailble we can route this to a backup fax.

Good luck

Hi

If you cannot use the good tip of Fidde (MD >BC10, or fax ddi range too large) , you may consider this alternative :

Set your ddi route sel D1 on 4 or 6. This will prevent rerouting on congestion ( this state should occur when fax server is down)but allowing rerouting on no answer or busy.
Use command rovni if required to reroute misdialed number to switchboard.

Hi!

Thanks for the answers.

RORNI, yes this would be a possibility. But when I wrote about this possibility (I've said D1=0) I tried to say that most customers want normal speech traffic to be rerouted to the operator in every possible case - also vacant number, no answer, busy, etc., so this is not really an option.
But thanks anyway.

FIDDE, this is an interesting input.
You mean the destination code of the FAX-Server should be changed to a generic extension that has PEN.
CHO 1 points to the RODDI ot the route of the FAX-Server and CHO 2 to some other endpoint (analog FAX, whatever)
But won't the rest of the number be cut off?
EG:
FAX-Server access code is 99, so if you want to send the person with extension number 1111 a FAX you dial 991111.

When I program a generic extension 99 instead of RODDI, won't the 1111 be dropped?

I'll give this a try - this is interesting.
