sundance-communications.com/forum Forums TDM Business Telephone Systems Samsung Telephones & Systems LCR COS MMC 310 MMC 712. How does this work?

(note, I have been running LCR for over 2 years.. I just changed COS 2 TZ 1-4, to use a local pots line instead of an intergrated T1.. for just my extension.. It didn't work.. I had the same trunk# for all 4 timezones... and then i went and set COS 2-8,TZ1-4 all to local, and left COS1/TZ1-4 to the LD.. it still didn't work.. It still grabbed COS 1

This is Exactly what has happen to me. It does not seem to recognize the different Least cost routing classes of service!

No matter which COS you set in MMC 310 for the extention and no matter what you tell that COS to do in MMC 712. It will always treat the call as if it were COS 1.

Thank you for finally checking it out yourself! I think this is a flaw on the samsung phone system because I followed the manual exactly and it still does not work!!

Its very hard to tell a customer that its not your fault because the equipment has issues.

Hi wrichey

Did you have any luck with testing this out?

Thanks.

Make the ext LCR COS a 2
It is default a 1 and it will not follow table 2
The MMC escapes me at the moment but scroll through the mmc list and you will find it

------------------

Do you mean in MMC#310 Least cost routing class of service?

I have made the extension LCR COS 2 and also assigned a different trunk group in MMC 712 for LCR COS 2.

I have done everything exactly as described in the manual however no change. It will still use LCR COS 1.

I would really like to find out if this is a bug in the system or if I'm doing something wrong. I have had other people tell me they can't get this to work either. I have never found anyone so far that has been able to successfully get this to work.

Please let me know if you are actually able to get this to work or if maybe this is something that Samsung should be made aware of?

Thanks.

Ok, What you have programmed is a feature called "Route Advance". What this means is that if the trunks in Route 1 are busy or have failed, any station with a LCR COS 2 will be allowed to advance to the next route, while the stations with LCR COS 1 will have a message displayed that says "Not Trunks Available".

If you notice in the Tech manual for MMC 310, it says that setting the LCR COS will allow that paticular station to advance upto that route level, however if a lower class is available it will use that route first.

This feature comes in real handy when you have a PRI and you need back-up analog lines. If the PRI goes down, it will start sending all calls out of the analog lines.

I haven't tested exactly what you are trying to do but I think I would try to use Station / Trunk use in MMC 313 in conjunction with LCR.

It is working as designed.
Just reverse your understanding of LCR COS

The system will use the FIRST COR allowed by COS for extension that is programmed to use LCR. It is done in MMC712.
That means if you have something in COR1 and COR2, COR1 will always be used (until there is no more trunks to use in COR1 trunk group).

To make it work do the following:
Setup RT1 (Routing Table 1) COR1 to only have your default trunk group for extensions that have no access to LCR.
You could assign all faxes to COS1 so that they dont get affected by it.

In RT2, COR2 set your alternative route (Lets say VoIP) and in COR3 your default (ISDN). Leave COR1 empty.

That way, any extension with COS3 will be able to dialout by default via COR2 which is VoIP and if all trunks are busy or unavailable, it will dialout via default (ISDN) trunks as a backup.

We have this system going perfectly with OS500+Asterisk.

As the TheTelephoneMan said, its a Route Advance rather then LCR.. All you have to do to make it work as LCR is to reverse your COR's.

If still confused, let me know, i'll help you out.

P.S. Cant delete my double post

Just following up, I wanted to let everyone know that the MMC dealing with Station/Trunk use worked to restrict certain extensions from using certain trunks(that would normally be selected based on the number dialed)


For example, if you have all instate call going over VOIP trunks. You would need to restrict extensions connected to Faxes from calling out on the voip trunks.(Due to the fact that faxes don't seem to work on VOIP)

Thanks for your help.
