"dmesg | grep OpenVox" output:
Found an OpenVox G400P: Version 1.1
In Asterisk CLI:
gsm show status 1
chan_dahdi.c: GSM 1: cannot request GSM status, module is in use
gsm send sms 1 XXX "test"
chan_dahdi.c: GSM 1: Cannot send SM when in state 25
The current version is chan-extra-2.0.1 based on DAHDI. We strongly suggest you install chan_extra rather than Bristuff because we developed a lot of new features like stronger SMS feature, muti-platform support, higher versions of Asterisk support etc.
