[firque]

hi all

i am need gnokii (or any other piece of software) to send sms to multiple users at the same time. i have been trying for hours now and i can only send it to one user.

any ideas?

i need to use the serial gsm modem we bought. sms services on the internet are no option :-)

thanks for the help

You also might want to check out SIGNL4 (https://www.signl4.com/) that can send Push, SMS and voice calls. It is available as a media type in Zabbix and also supports two-way communication, i.e. acknowledgements and annotations are send back into Zabbix.

Hi,

What you’re facing is quite common when using a single GSM modem with tools like Gnokii. A single modem can usually send only one SMS at a time, so if you try to send to multiple users simultaneously, it ends up queuing them rather than sending in parallel.
A few things you can try:

• Use a queue-based approach where messages are sent sequentially but managed efficiently (Gnokii can handle this with scripts).
• Increase throughput by using multiple GSM modems (each modem handles its own queue).
• Check modem settings like SMS mode (PDU/Text) and ensure no delays are configured between sends.
• Consider tools like Kannel or Gammu, which are better suited for handling bulk messaging with modems.

Keep in mind that with a single serial modem, there’s always going to be a hardware limitation on speed. True parallel sending usually requires either multiple modems or a gateway setup.

Hope that helps
