Is there a digital type of call for sip ? (without joking)

hum .. i thought my idea would even add quite more 
multiprotocol-features to asterisk ?!

No, i really think that depending on  (ast->transfercapability == 
UNRESTRICTED_DIGITAL) && (ast->bridge->type != MYTYPE) we can safely 
send our hdlc data with a AST_FRAME_DATA to the remote channel driver.

I don't think we should natively bridge between different channel 
drivers at the moment. Maybe we'll have later some thing like a 
zapte2misdn bridge, but this needs to be investigated more deeply.
