ghe gsm modems are actually not a real SMSC as it submits a SMS-MO to a real SMSC who then delivers it to the destination. As such the deliver over a GSM modem is working the same way as if you would type an SMS on a phone which results in the SIM card's number to be sent as originators.

Some of the modems of today do support GRPS networking (as tcp/ip). If you talk about access from kannel to the gsm modems, there are some devices which have a gsm modem built in and then present it on a ethernet (usually for IP dial-out). Kannel doesnt need TCP/IP to talk to the modem but a serial port. I have some boxes out of china which connect 16 or 32 or 64 GSM modem to a computer by a simple USB cable. The computer will get the same amount of serial ports which then can be used directly from kannel.
