I have it here. Though I didn't have much luck with newer systems. I have moved to external gateways Yeastar has some inexpensive that work well. Have used Grandstream to much echo and Audiocodes which seem to loose their configs if site has power issues
It seems to have compiled ok this time with 99.7. I'll go back to the customers site tomorrow and throw the card back in and see what happens. I've had to put the old openvox card back in for now, which is suffering from not detecting when the far end answers a call when dialling out. Inbound works 100% and the config is exactly same as the old system. I had this Rhino card kicking around so I thought I'd give it a go.
Unfortunately here in the UK Yeastar gateways seem harder to come by. I'm planning to move to a PSTN gateway so that I can use a backup server for this site, but right now I'm stuck.
