The patch I wrote works following:
1a. Extended Asterisk's channel structure (ast_chan) to store the 
userinformationlayer1.
1b. Extended func_chan to read/write this value
1c. Extended app_dial to copy userinformationlayer1 from incoming 
channel to outgoing channel.

2. Modify chan_zap and libpri to check if userinformationlayer1 is set 
(-1 means that is is not specified = default value). If it is specified, 
and transfercapability is VIDEO, is will set the values in libpri.

Thus, you could reuse 1a-1c, but in the second step you have to add this 
modifications to chan_misdn.

The values for userinofrmationlayer 1 are defined in Q.931. Usually it 
is a-law or µ-law. The value for H.223+H.245 (this is a 3G vide call) is 38.
