Hi,

I am using the Q931 / ISDN USER-USER-INFO field for transferring data 
between the caller and the called party.
This works fine as long as the information does not exceed 35 characters...
Unfortunately sometimes I need more space and due to the Q931 Specs I 
think there should be space for max. 128 octets (bytes/characters)...
Can someone point me to the place in the sources where I can check and 
adopt this?
I have tested this on an asterisk 11.3 and on an asterisk 1.6.2.24.... 
both show the same limit of 35 characters...

regards,
yves
