One Way Speech - Digital Sets 2

[CTCINY]

I have a customer stating that they are experiencing one way speech path on 4 of there digital sets. They have over 150 sets. The only thing that these sets have in common are that they are supervisors in there call center. They say they are experiencing the issue whether they are logged into the skillset or not. Has anyone had this issue before? How was it corrected?

Is the system up to date w/ patches?

Hey CTCINY:

1) what software release are they on
2) what hardware platform (Bcm 200,400 50)

If BCM 400,

3) How many PEC3 cards in your MSC?
4) What version of call center (basic or PRO keycode)
5) any IP sets in use or wireless sets (companion?)
6) What's your Split & Density
7) How many digital Stations on system
and the modules ( qty. of DSM32s)

and if you have an expansion chassis, are the sets
on a DSM32 that resides on the expansion chasis?!?

Also, did this just start? Did they just start using SM
on the sets? New installation, new programming to use SM?

I'm sorry guys, BCM 400 4.0. 4 PEC cards. Site has 3 DSM 32+ cards and 3 PRI. Site also has 60 IP sets. Last patches installed I can see is February of this year. One of the phones is on the expansion mod and the other 3 on the main cabinet. They have Pro CC with a 2/6 split. These users have been using SM since installation. Only thing I noticed tonight is that in BCM monitor it shows media resources at 100%. N ow I could understand that causing issues in CC or VM but what would that have to do with digital sets and one way talk path.

Should use 3/5 split. Sounds like there aren't enough DSP resources for everything.

 

[markelbcm]

Make's sense to me. With 3 x DSM32+ (if full, that's 96 sets)
plus 60 IP sets, thats 156 total. If i recall, the more IP sets you add, the more time slots (DSP resources go missing).

If you have added more sets recently to the BCM without perhaps noticing that this new 'side effect' it stands to reason if you 'tead down' some sets and test too see if your voice resources come back, you've isolates the issues.

As Dasheen made mention, the 3/5 split would most likely fix the issues because the split you choose is determined by the number of signaling channels you require for applications such as voice mail, IVR, IP trunks, IP telephones and dialup ISDN WAN connections. If you need 58 signaling channels or less for these applications, use a 2/6 DS30 split. If you need 59 signaling channels or more, use a 3/5 DS30 split.

Based on the 60 IP sets in use.. you need more resources, so the move to 3/5 makes a lot of sense!

You can change from a 2/6 setting to a 3/5 setting without losing data.

Warning: Ensure that the system is idle before you do this procedure. The system needs to be restarted after the setting has been changed. DO A BACKUP!

I'd recommend reading the BCMs context sensitive help:

OK that makes sense to me. The only issue is they have 3 PRI circuits. Maybe I will have to talk them into adding more IP sets and changing the DS30 config. But I was under the impression that by chaning the DS30 spilt into efaulted the programming.

If your usin 3 DSM 32+ and 3 PRI that 6 Bus being used, so it needs to be 2/6. They should have gotten a Option 11




This is a Signature and not part of the answer, it appears on every reply.

This is an Analogy so don't take it personally as some have.

Why change the engine if all you need is to change the spark plugs.

 

[markelbcm]

He seems to have a 'full house' with 3xDSM32+ & 3xPRI @ 6 full bus's in use.
The other thing CTCINY might want to look at
is the CODEC's in use for the IP sets on the LAN:

(from the help files)

The number of DSP resources you need depends on the features
and type of codec you are using.

# IP telephone or IP trunk using G.711 codec uses 1 unit
# IP telephone or IP trunk using G.729 codec uses 3 units
# IP telephone or IP trunk using G.723 codec uses 4 units

So if you got them of .729 for saving LAN bandwidth, the PEC
cards need more resources to encode/decode to the TDM calls.

(no sure if this is applicable) - Yes, it's a short cut
but less scary then a split change! #-)

You could try to set a few sets to G.711 and see if this
fixes the 1-way voice issues, and, narrow down the issue
to lack of DSP resources. ?!?

I'll give it a shot on Wednesday. Thanks all i'll let you know how it turns out.

For future reference, going from 2/6 to 3/5 will not default, but going the other way will. That would fix your DSP issue, but does not look possible considering your hardware. At about 60 IP sets, problems start w/o 3/5 split.

Also, after completing split, IP sets come up one after another. If, people start using their telephones w/o waiting for all to come up. You'll expierence wierd issues, like group P/U not working. (reboot fixes).

So, I learned, do after 5:00pm instead of b4 8:00am.

 

[Dasheen]

If they want to keep their BCM, you'll need to find a way to free up a bus so you can go to a 3/5 split or you'll have to sell them a larger phone system such as the opt 11.
