The reason for this seems to be because there's not really an AT command to
query the modem for the MSISDN of the SIM (that is the 'destination' number
in this case). That said, normally there's no way, but some providers write
it into the "ON" Phonebook of their SIM card but there is no specification
from the GSM Standard that they must do it. For a Siemens M20, you can try
to see if you have some entries in ON by using AT+CPBS="ON" and AT+CPBF="".
I think there's a similar command for the Wavecom. The MSISDN is only stored
in the HLR at the provider, GSM mobiles do not have access to it, the IMSI
is used for dialling purposes, so short of making this "number" configurable
in the smsc group for at2, I don't know what could be done, any comments?
