I made the changes in the q931.c sourcefile and got rid of the 35 character constraint.<br>
thanks for your attention.<br>

seems, I found the right place by myself... no wonder I could not find it in asterisk sources....<br>
the constraint is located in the sources of libpri.... I will change that, recompile and post feedback here...<br>
<br>
thanks anyways,<br>

Hi,<br>
<br>
I am using the Q931 / ISDN USER-USER-INFO field for transferring data between the caller and the called party.<br>
This works fine as long as the information does not exceed 35 characters...<br>
Unfortunately sometimes I need more space and due to the Q931 Specs I think there should be space for max. 128 octets (bytes/characters)...<br>
Can someone point me to the place in the sources where I can check and adopt this?<br>
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...<br></blockquote></blockquote></div></div></blockquote><div><br></div><div>That restriction has been there since the feature was put into the code.<br>
