Hi Moises!
Really it's related, but my thinking is make it part of dahdi, so we 
have only one "hardware layer". Not a different channel, because it's 
simpler and clever have only one hardware layer channel. I'm working at 
now on pci gsm multisim cards (opvx g440p). I'll have something working 
this weekend, but I'm using Junnghanns libgsmat library, as Tzafrir 
guided me, so in principle it can't not be added to dahdi trunk because 
of code policy (perhaps a rewrite of libgsmat solves it).  Working on 
signalling now....
