Is it possible to setup the system not to require 9 to reach PSTN?

[Derek Thom]

Hello-

I would like to know if it is possible to setup the system not to require 9 to reach PSTN? I saw this question on an FAQ regarding PSTN connectivity, and it was answered "You can configure the UC500 in keysystem mode, where the user can seize available FXO or T1 CAS to dial numbers directly to CO."

I have our UC500 currently configured as a keysystem, with our PSTN/FXO dial peers set up as shared-dn's on all the phones. On our old phone system, it was possible to just press a line button and begin dialing a number, or just pick up the phone and a line was automatically selected and you could being dialing (without having to dial a number).

Is it possible to do this on the UC500, and if so, how would you go about configuring it?

Thanks,

Derek

No more help required, this has been resolved (thanks for your help!).

Solution courtesy of Marcos:

Once you use CCA, you will see something like this on the CLI:

For each (FXO port in UC500) {

!

voice-port connection plar opx 3A10dial-peer voice xx pots description ** FXO pots dial-peer ** destination-pattern A0 port

!

ephone-dn xx

number 3A10 no-reg primary

label Line 1

trunk A0

}

The trunk lines are assigned to phone buttons the same way as any other DN – eg button 3:54. There is no particular mystery about the numbers A0 and 3A10 – they are just used to associate the DN, the dial-peer and the port. It is customary to stick one of the non-dialable DTMF digits in there somewhere to avoid accidental dialing, but it is not mandatory. It’s also a good idea to add the following config to enable hookflash for access to features provided by the telephone exchange.

!

telephony-service

fxo hook-flash

And that’s it.

I had the ephone-dn's setup as octo-line, so at first I could not use the "trunk" command, it would just "Unrecognized" from the CLI. So, removing the dn and readding it as a dual-line resolved the issue and I could create the trunk.

Basically, this whole problem occured because I did not select the "CO" check boxes in CCA. I had modified so much via the CLI, that CCA gave me an error when I tried to run it, so I couldn't make the change there. This was a long time ago when I set up the system, and had not been trained properly, so I winged it. But, having the knowledge now I am able to set up the system now no problem via the CCA.

Thanks,

Derek
