I'm having trouble freeing DSP resources for hardware conference option.
The platform is UC520, CME4.2 with 12.4(11)XW7 IOS.
It has following built-in interfaces: 4FXO, 4FXS, 1MoH
It also has a PRI wic.
I'm using just the 2 FXO channels and 12 chanels on PRI card.
In this case 24 channels are used on DSPs (the sys. has 2 DSPs=32ch,
12 used for ISDN, 2 for MoH, 4 for FXS and 4 for FXO),
and I need one hole DSP for hardware conference.
I can shut down the unused FXO and FXS interfaces, but I got the
information that shutting them down won't free channels reserved for them,
due to hardware allocation of DSP channels for built-in cards.
Is it possible to free DSP channels allocated by built-in FXO and FXS ports?
