ICB 4.0 problem

[stokerel]

I have a cs1000e 5.0 system, new install, with a PRI line and a ICB rls 4 installed. I use IP Phones as extensions.

When I dial into the conference bridge, either from the IP phones, or on the PRI line, the voice prompts are very noisy and distorted; the users barely understand what the conference asks: name and password on login.

Do I have to worry about the ICB being defective? I couldn't find anything in the NTPs regarding this possible issue.

Thanks in advance.
Radu.

have you rebooted the MICB card? try that first, otherwise I had that happen once and it was a bad card!

 

[stokerel]

yeah, I tried rebooting. Thing is this issue only appears on the ICB. Other calls have perfect voice quality, so it must be something with the card.

 

[phonz1]

yeah, i'd imagine that the DSP's are a little hot.... time for a new one.........

I've noticed something on the reboot: the card is setup to use mu-law. How do I change this to A-Law? I'm in Europe and I have the phones and the PRI set to A-law.
I'm browsing through the debug cli menu now, but there is no NTP describing the commands.

I've managed to solve the issue partially by manually converting all the wav files to a-law. Now the voice prompts are no longer distorted, but I still have a problem that happened before the change. When I try to use a dial-out group, I get this message on the ICB serial port:

0043 DEBUG PH171 03-13 09:20:34:510 phth_audit: dsps error on port 4

0044 DEBUG CNF043 03-13 09:20:34:511 Cnf104: FATAL error in state 4: orig.=3, reas.=3, memb.=4. Session crashed!!!

0046 DEBUG APP012 03-13 09:20:35:793 Drainer: SIGNAL_ERROR, port- 4


Also, on the call server I get an err message: ERR049 4 0 2 8

The Terminal Number is in unplugged state (locked out), so it cannot
process a force answered call. The system puts the associated set into
Make Set Busy state.
Plug in the set. If the set is still out of service, check the wiring.
Severity: Minor

I verified the icb ports I defined as 2616 sets, and everything seems fine, but still doesn't work.

Could it have something to do with the fact the ICB's DSP is still configured to use Mu-law?

Just curious, if you unplug one of your phones being used in a Call Center that has nothing to do with the ICB do you see the ERR049 code show up for that logged in phone?
