Cool things that are as simple as changing the CLS An Original Composition by Gene of GHTROUT.com
Sometimes system administrators are rushed through building phones... things get overlooked and available features are never released. In this short refresher, I'll go over just a few of the CLS entries old timers might not know exist, and hopefully get you interested enough to study the other 300 possibilities. (See the last section for a neat download). Here we go:
ARHA will remind users they placed a call on hold or that an incomplete conference hold is still waiting.
CFHA enables you to override Call Forwarded sets and continue ringing beyond the FNA timer. You need to create a Flexible Feature Code, so if only you know the code, it can be added to all sets, enabling only those with the code to use the feature.
LNA Last Number Redial. I mean, all your sets have this, right?
FITA – Digital Sets - Off-hook buzz repeats like regular ring. With so many headsets and so few handsets anywhere to be found, this is a nice feature and it's not too annoying. (Also add DBA to Customer Data Block OPT).
RNGB and RNGI - Whoa how about replacing CLS BUZZ with one of these. RNGB - Apply ringing (Yes, like regular ringing tone) when idle but off hook or busy on the other line. RNGI - Apply ringing when idle but off hook
XFR – Analog/500 Sets Transfer Restrict. This is one of Nortel's greatest feature additions ever. Considering the previous two options were XFA "Hook Flash Allowed", or XFD "Hook Flash and Ring the Attendant". Can you imagine all the modem lines that kept tying up two lines or alternatively bugged the Operators if the timing was a little off? I could go on, but lets just agree I think it is great.
TDD – Display info for DNs other than Key 00 before the handset is lifted. I say never roll out CLS TDD without a test period. Add TDD to a department and see if ringing and display is affected. Trust me, I rolled it out to 2400 TNs and had a terrible day. Thank goodness for ProComm Scripts. Related to display, if you ever build a lot of digital display sets with the same DN on the same line card, you might notice the ringing and display can't keep up. Sets the CLS to DDS (Delay Display) and ringing returns to normal in many cases. But it's better to move the TNs across various loops and groups.
DDGD – Block your DN from showing to other sets. Caution. It's really hard to test phones with this CLS since you cant ask someone "what number am I at" – I suggest not using DDGD.
UNR or CTD. Does the user have any need to dial Trunk Route Access Codes? If no, then use CLS CTD. CTD is exactly like UNR during dial-9 BARS calls. It only restricts "ones and zeros" on direct dialed route access codes.
OK, this is a start. I hope this mini-list prompts you to read up on the other 300 or so possible CLS entries that exist. I have compiled a unique list of CLS entries and made it available at my web site. GHTROUT.com.. One last item..."how can I identify what TNs have a particular CLS?" You can do that in LD81, requesting a "count" or a "list" of all TNs with a particular feature or CLS.
