It's not always 100% correct:
S0*CLI> gsm send at 1 at+cscs=\"gsm\""
OK
S0*CLI> gsm send at 1 at+cusd=1
OK
S0*CLI> gsm send at 1 atdt*142#
+CSQN: 16, 6
S0*CLI> gsm debug span 1
Enabled debugging on span 1
S0*CLI> gsm send at 1 atdt*142#
1:<<< 0 atdt*142# -- +CSQN: 11, 5 , 12
+CSQN: 11, 5
1:<<< 0 atdt*142# -- +CUSD: 2,"Your account is X.XX.....",15 , 167
1:<<< 1 atdt*142# -- OK , 2

Generally speaking it's a bug in chan-extra. It always passes the first received line from modem as an answer. To fix it - simply check return lines. They have codes in them, as +CUSD: in this case. So there is no mandatory requirement for the modem to give an actual reply in the first line.
