[asterisk-ss7] Transmission Medium Requirement

[Kaloyan Kovachev]

Hi,
 you will need to make a patch for that as currently it gets a fixed value
- check isup.c for 'transmission_medium_reqs'

Also there is a bug as 3.1 kHz is marked to be 4 instead of 3

4 and 5 are unused

6 is also spare (like 1) and not 64 kbit/s preferred while the rest are
not used according to ITU Q.767 [1] page 170
