using notepage with GSMAT in bad coverage area

[ramin]

Dear all,
We want send alarms in our monitoring system (solarwinds) by sms. We have orion network performance monitoring v7.8. We can use only GSMAT protocol (with GSM modem) to send sms by notepager pro 32 software. We have one problem:

The monitoring server is located in a special server room that coverage of GSM signals is bad and gsm modem can not detect simcard. Gsm modem is connected by serial (RS232) port to server. Nearest place that has good coverage is about 40meter far. Is there any solution about this problem?
For example sending output messages of solarwinds through network and then getting these messages from another client that is located in good coverage (and in same LAN with server), send by notepager and gsm modem that is connected to it. Or another solution that you think is good for this situation.
Your help is high appreciated. Thank you
