Hi,
I hope someone can help with this odd problem.
I have a TDM400 card with an FXO port and an FXS port. The FSO port is connected to the PSTN and I can make and receive calls from a SIP 'phone.
The FXS port has an analogue handset attached to it. I can make calls from the handset to both internal SIP extensions and external numbers via the PSTN. Unfortunately, If I try to call the analogue handset from a SIP extension or from an external phone via the PSTN, it rings and answers when taken off-hook but it neither sends nor receives audio.
Any assistance gratefully received,
Regards,
Dave.
