regarding sending sms alerts with xymon

Hi, we have xymon 4.2.2 on RHEL 5.3 OS installed for cluster with 32 nos of nodes for monitoring . We are trying to integrate sms alerts with xymon. We have sms server with smash and gnokii setup. How we should integrate this server with our xymon server so that is can send alerts.

Thank you, -Akshar B. NDF Computech
