To archive this I made the following two changes to my n900:
1.) Install the new pulseaudio package provided by the user MohammadAG as discussed here
2.) Set the processor speed to 600MHz (fix) during sip calls (I think the stock kernel does this, however it seems not to work with the power Kernel).
To set the processor speed to 600MHz during a sip call I use a dbus script. I added the following config file to the /etc/dbus-scripts.d/ directory with the following content:

Code:

/usr/sbin/speedadaptnormal * * com.nokia.mce.signal sig_call_state_ind active *
/usr/sbin/speedadaptfix * * com.nokia.mce.signal sig_call_state_ind none *

And created the two files in /usr/sbin/.
speedadaptfix

Code:

#!/bin/bash
echo 125000 250000 500000 550000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies
kernel-config limits 600 600

speedadaptnormal

Code:

#!/bin/bash
echo > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies
kernel-config limits 125 1000

As said before this works perfect for me. No choppy audio anymore!

It does appear that the key problem is a CPU load problem, so I wonder if the encryption will work if I push up the call frequency to 800 instead of 600
