Siemens MC35 as a Gateway into the mobile network

Dear Experts,

perhaps someone of you have tried it already, to get the Siemens MC35 GSM-Modem working with asterisk? Does this work? If someone have some experiences with this Modem together with asterisk I would be verry happy for some suggestions, because I would like to use this modem as a gateway for calls into the mobile network.

Many thanks in advance
