Best Regards, Openvox friends, write with concern this post, for about 8 days ago has been presented an anomaly which I am not sure if failing to come before the firmware upgrade of the GSM modules. the problem is that in a call, a second ring tone, a second call GSM listening, I wanted to ask them if there is any feedback about this problem. if they have any experience of this failure and its solution they would be very grateful.
for now I will proceed to restore factory all 60 modules (3 Openvox GW1600) and discard some configuration problem.
Audio Attachment what you hear on the call
I try to attach but the file is big to this forum, please download via gigasize,
Sorry for the inconvenience, two questions:
1. please tell me the version of your gateway's firmware
2. you mean one call is processing on gsm module, then a second call is coming to this gsm module,
you can hear a ring tone in your prev call?
