How can I setup a DISA line?

[ramavi]

I need to give external users access to our private voice network and have been asked to setup a DISA line.
I have a digital link into the pbx using DID lines and then TIE lines between our different locations. I know the DISA number would have to be within the DID range. Any simple procedures or do I need to call in a vendor.

Hello ramavi,

I'm not sure what a DISA line is, but it sounds like you need to set up remote-access. This will create a DID number outside people can call, and after entering a pincode, they can call from within your switch, and also your private network (if you set the permissions right).
Carefully select pincodes, and change them frequently and if possible 6 digits lenght or more, but no less than 4.
You can also create a special COR to only allow remote-access callers access to local & remote extensions, but not the public network.

The command is "ch rem" (I believe, it's been a while), you have to enter a free (DID) extensionnumber, and set the access codes (you can actually set 2 codes, wich is more secure, but often not accepted by the users), COR, an expiry date, and a maximum number of calls. You can enter different codes that have different COR's as well.

Watch your CDR logs when you've activated remote-access, and if you see any irregularities, disable remote-access and find the cause, or you'll be losing a lot of money.

Cheers,
Nico

Thanks for the info. Apparently our system is not setup for the remote access option. The money people don't want to spend any to get it added. Oh well.

Nico - DISA is Direct Inwards Systems Access, usually used for programming rather than sitting on the switch itself.
Ramavi - One thing you could lookinto although it isn't particularly cheap would be setting up IP agents in the Telecommuter config, this would allow them to sit on the switch without going to the extent of say installing network alchemy and you dont need hard phones as the users could set-up IP softphone on their laptops

My boss doesn't want me to say this (I work for Avaya), but I think Definity remote-access is a lot cheaper, and easier to implement/maintain as well. Apart from that the IP solution requires users to have both an internet connection as well as a free telephone-line (or a very good internet connection, but most public internet services (including cable/xDSL) are not reliable enough to seriously transport VoIP).

But I agree that IP softphone is a much cooler solution, and it will help us to reach our Q4 targets too
