Different Number for each Nagios alert

[moncapitane]

I am using Nagios Core and I have set up SMS messaging for alerts. Why does each alert come from a different number. Each of them come from a 4 digit number like 6996 and 6999 instead all from the same location. Is there a way to set it up so they come from the same location instead of getting individual messages for each alert?

How do you have it set up? Is it via email using the [email protected] method? Or are you using a SMS gateway or some other option? If you are relying on a third-party implementation of SMS (which from the Nagios standpoint they all are) then we don't have a lot of control over what number may be used by their protocol.
