Hi, A company I work for provides System Support Services. We are looking to SMS-enable some systems we support. Having played around with Kannel before, I think we may be able to use it for this purpose. The set-up I foresee is a dedicated server running Kannel, and a number of front end applications (mostly web based) and scripts communicating with the gateway. To begin with, we will be sending strictly MT messages (one way). Our monthly volume estimates are 50,000 messages in the first year.
I have a number of questions especially for people who have used Kannel in production. 1. I want a general feel of the hardware requirements that would work for our scenario. I was thinking we start with a leased dedicated server, with 2 NIC cards, one for communication with the SMS service provider via SMPP and one for our apps (HTTP). We have internal Ubuntu expertise so we will most likely run Kannel on a Ubuntu server. 2. Bandwidth requirements: If we are to lease a server, or opt for co-location, how much bandwidth should we pay for from the co-location service provider? We intend to enable DLR feature. I believe the traffic would be only SMPP messages including DLR and HTTP requests and responses. 3. What are your experiences with Bulk SMS service providers? We plan to go the operator route in the future but it appears our volumes may not be big enough to get direct connections to their SMSCs. Which provider are you using and how would you rate their service? Thank you in advance for your help. Kind Regards, Engel Linus
