One of my customers is having a problem with ad-hoc conferencing.
I found an error in their config and have been trying to fix it.
Their config is:
dspfarm profile 1 conference
description DO NOT MODIFY, active CCA conference profile- Using codec711
conference-join custom-cptone CCAjointone
conference-leave custom-cptone CCAleavetone
associate application SCCP
When I try to change it to "no shutdown", I need to specify the max number of sessions.
But, the only number I can put in is 0.
Using some of the answers to questions on this site, and others, I tried "show voice dsp group all"
This shows a failed state for DSP2:
State: FAIL, firmware: 1.1.137
Max signal/voice channel: 16/16
Max credits: 240
Transcoding channels allocated: 0
Group: FLEX_GROUP_VOICE, complexity: FLEX
Shared credits: 240, reserved credits: 0
Signaling channels allocated: 0
Voice channels allocated: 0
Credits used: 0
When I look at "show voice dsp signal", it reports a non-default firmware for DSP2:
Warning! DSPs2, in slot 0 are using non-default firmware from flash:
This is not recommended, the default version is 21.4.2
Is this something I can fix?
If yes, how?
They're using an 8user UC520, 7936 conference phone, and an older version of the IOS. (Can't recall exactly which one)
