Hi all,
We have problem with call recording. :(
problem is that, when call recording is active (manual or auto) we hear noice on IP phones. I tried this issue with 2 IPO 500 systems (system version 4.2.11, 4.2.14, VM PRO versions - 4.2.24, 4.2.27). Problem exist on both.
Mabe this can be a VCM problem? External trunks is connected trough SIP, and used IP phones. VM PRO operates at TDM Bus, that for all call recordings is used VCM... :(

I have asked my partner abaut this issue. This problem exist to, when a ISDN trunks is used (The same system: IPO 500 vith VM PRO, with ip phones)
 
Hi all,
I have changed all members ip interfaces (IP phone, HP procurve Switch ports, PC running VM PRO/ContactStore NIC),to 100Mbps Half Duplex (not auto), but the problem still exists.
I have tried change all combinations - 100 Mbps Half duplex and 100Mbps Full Duplex, but the problem still exists.

any ideas?
:(
 
Hello,

I have tested that problem with new IP Office 500 control unit.
On new IP Office 500, with 4.1.12 system, all is OK, noise not appears.
When I upgraded that system to 4.2.14, we hear the noise, and after downgrade again to 4.1.12 that problem was solved.

After that, i contacted Avaya support.
answer is:
"Please do next change and test again.
1) Change some settings in IP phone:
in IP phone OPTIONS, AGC Settings\Handset AGC Enabled(default), change to Disabled;
Then, test again. If the noise still exist, please continue to step 2).
2) In IPO config System \ VCM, Nonlinear Processor Mode: Default = Adaptive, change it to "Silence".
Then reboot the system, and test again. If the noise still exist, please continue to step 3).
3) In IPO config User\NoUser\Source Number, add source number line "CONFERENCE_DSP_TX_GAIN=-2" (the value may -2 or -3 ).
Then save config and reboot the system, and test agin."

after i change VCM setting from Adaptive to Silence, problem was solved.
 
Thanks Orintas for letting us know, most people are just gone after the problem is solved and don't post the solution they get from Avaya, have a star.
