Alcatel Unleashed

Hi everybody,

Does anyone know if it's possible to have an DDI as a Professional Trunk Seize prefix?

I managed to create it, but when i Call it, i receive a 9c NUMBER FORMAT ERROR from ISDN trace.

The idea is dangerous, but the client wants to call a local number and get the tone to dial for their voice channel on the company.

This voice channel is an ISDN TG linked to a Cisco router, that only make calls for the other company units.
TG with Cisco is working fine using local prefix, from a local set, and the client wants to call from outside and use this voice channel, instead of making a long distance call.

I know DISA is an option, but the client does not want to authenticate, substitute, etc, they want to have the tone automatically.

Thanks!

From your client point of view it is not necessary to know they have DISA

Yes, but how can i have DISA doing this work directly? I can't (as far as i know) do automatic substitution since I don't know the numbers they will use to call.

And is it possible to use DISA for a DDI directly and other DDI doing substitution?

Thanks

Not clear what you want.
user from outside dial some number, hear dial tone and after this dial internal PBX number (not feature)? This is usual DISA function (just not use 106 VG - DISA announcement).
Or you need to dial what you want (feature, outgoing seizure prefix...)? In this case you need to use or DISA with automatic substitution, or Remote extention (Cellular client) feature.

Hi vad, thanks for your reply.

I think it's possible to use DISA without the 106 VG, i just don't know how to make DISA work without making the substitution.

I can't use automatic substitution and remote extension since the number will be public - not only for company users, but for suppliers, clients, etc.

What i really want is:

I'll Dial the public number 3033-4444 that is a DDI for my OXE and arrives in TG 102 for example, and want to hear the dial tone for the TG 202.

This 202 TG is a special ISDN TG linked to their private network supplied by Cisco Routers, that accepts only specific numbers, that the person calling will know at the time they call.

I managed to have it working using DISA but the client is needed to use the Substitution PREFIX + OXE USER + PASSWORD, get the user dial tone, and then DIAL *3 that's a Professional Trunk Seizure prefix for 202. That works.

I would like to remove the need of dialing Substitution PREFIX + OXE USER + PASSWORD + *3.

Thanks

Substitution used for security reason.
If you have no problem with security - what you can to do. After DISA call you can dial internal user number, substitution prefix and SPEED DIAL!!
You cannot dial seizure prefix (TG202, *3) but you can create speed dial (f.e. prefix #3, call number *3, barring unchecked). This is idea - not allowed to dial seizure prefix but you can dial speed dial (where call number=seizure prefix).
So after DISA call user can dial #3 (Speed dial), PBX will dial *3 (TG202 seizure).

But how can i configure DISA to not check internal user number?

Just the Speed Dial, for example?
