Thanks a lot for all your answers. For an internet SMS gateway we have a solutions (yes, we are ip+ customer). I'm more searching a hardware solution (to be independent of connectivity to the internet which can also fail).
There is also YaPS [1] available, which can use any modem and the UCP gateway of Swisscom (dial-in with modem / ISDN) to deliver SMS. I had implemented YaPS at my last job for alerting and the customer SMS gateway. With the UCP Gateway you can define the sending number of the SMS.

I could not find the document "Computerlösungen für TELEPAGE® und NATEL® message (SMS)" any more on the Swisscom website with the listed phone numbers for such services.
The UCP gateway is available with analog (079 499 89 90) and ISDN (with V.120, 0900 900 941). The Tarif for the ISDN number was back then (around 2002) the following, probably has changed now:
The 2.second costs -.30 CHF, afterwards -.79 CHF/minute (in -.10 CHF steps). So a connection duration from 2 to 9.5 seconds costs -.30 CHF. This information were from Swisscom (Tel. 0800 848 900).
I know, it is a little bit expensive, but independent of any internet service or mobile phone in the datacenter. If I remember correctly, there is also the possibility for a 'large account', if you are sending a lot of SMS this way, which should give you cheaper rates. Ask your phone carrier. ;)
If you are interested in this solution, I can send you some more information and even a patch so that YaPS also can use some special characters (@ sign, Umlaute, ...) with the Swisscom SMSC. Probably I should once take some time to document and publish this properly.
