you mean when you call numbers of mobile phones?

this means the capi driver (in your case the AVM driver) is not accepting
the audio data.

There was no change in that code for a long time.

Changing this value should not be done and has no effect for sending data.

No, for any capi application like chan_capi, it doesn't matter which number 
you dial. It seems that your telco is doing something when you dial those 
numbers where the AVM card has a problem with.
Please create a verbose log with
   set verbose 5
   capi debug
for such an outgoing call (until you get these errors).
