Mitel 3300 Music On Hold vs Background Music

Before going too far with this idea I would want to know the size of your voice network (# of phones) and total amount of bandwidth available. Unlike the old TDM systems (SX2000), background music to the IP instrument takes as much network bandwidth per instrument/u] as a voice call. I don't think this is wise, especially not in large deployments. I'm not 100% certain but background music may also impact other system resources, such as # of available E2T channels.
ACD supports multiple MOH sources.

MitelInMyBlood. You're correct, each IP set will consume one E2T channel.
NEVER EVER use Background Music on IP Sets!!!
As noted by others, an E2T channel is consumed for each set. Depending on your Controller type, there are limits to the number of E2T channels available.
As you have only 30 sets, I would assume you are using a CX or CXi. These models only have 32 E2T channels. The system will become unstable and possibly reset if more than 16 channels are used for Set Paging or Background Music.
Even if you have an MX or MXe (without expansion processor) your Maximum allowed is 32.
Tell them to use a radio or Ipod and leave the phone for what it was designed to do.

We have a 3300 ICP and currently use set paging on all of our 5340IP phones and have never had a problem. The Background music will not be used on all the phones, just about 5 max (supervisors only). The background music source would not be music. It will be radio (Public Safety and dispatch info, from a HT source that we provide). Although I understand your recommendations against it, If possible I would like to test the idea.
rtank, just because it works doesn't make it right.
The system will not prevent you from programming more than the limit. The group will accept up to 250 Members. It is up to the programmer to heed the design recommendations.

rtank, as kwbMitel said, 50% is the recommended limit for paging. If there are available E2T channels at the time of the call then they will be used and all is well. The 'problem' is that say you have a CX (32 E2T channels) and 15 of your sets are on trunk calls or other calls that use an E2T channel. Now one other guy does a group page to 30 sets. Only 16 of those sets will actually get the page and the user will have no indication that the other 14 didn't hear anything.
As for the programming, I don't have an answer for you, but I could play around (if I can find time, no promises) and see if I could get it working. Unless someone else knows the answer for sure.

Hi IrwinMFletcher…
I have a 3300 MXe, not a CX or XCi as kwbMitel assumed. (Sorry for not being too clear about the model.) I do understand "just because it works doesn't make it right." But I also understand that even thought it is not the most efficient method it might work for our needs.
If you have the time I would GREATLY appreciate your help or even some direction to look at.
Everyone – Thank for taking the time to consider the possibility of this.

It looks like the answer is no. Only tenanting provides multiple MOH sources. In addition if you wanted live radio playing it would have to be off of the AMB (or ASU), which would leave any MOH files to the embedded variety.

We do have tenanting enabled (tried this solution), but we still find that somehow the external MOH source (Live Radio traffic) was played SOMETIMES for on-hold callers or when callers were transfered from our Auto-Attandant, or when transfered from one of our other sites (also using 3300 ICP MXe's). As far as the embedded MOH for callers, that is no problem, we just use some pubic domain files.
It was worth a try!

The risk is not just that users might not hear pages or music but that the system will actually spontaneously reset.
I "discovered" this undocumented "Feature" by programming too many IP sets in a page group. You've been warned.

KwbMitel, you took the words right out of my mouth.
"You have been warned".

rtank, the 'sometimes' probably isn't random, it would matter on the call scenario and who initiated the hold. Check the COS option Local MOH source.
I can understand what kwbMitel and MIMB are saying, and you should heed the warning, but if you are confident of the engineering of it, it should be fine. There were issues with systems resetting when you would attempt to page a group that exceeded your E2T resources, but that has been fixed. The risk is that you may not actually page people that you think you paged....but of course this is always a risk. How many phones do you have on the system and how many trunks (both TDM and/or IP/SIP)?
