Error when trying to send sms with gsm modem

[attilla]

I connected a gsm modem to my zabbix server and I'm trying to send sms messages, but I'm seeing the following error when a trigger becomes true:

Expected [+CMGS: ] received [+CMS ERROR: invalid text mode parameter]

I'm guessing that it is missing the number for the sms service centre, but I have no idea where to configure that in zabbix and the documentation is ehm .. very minimal.

Can anyone enlighten me on this one?

Nevermind, I used a script to send sms messages instead of the gsm modem implementation in zabbix
