Good morning. I placed a cisco phone in a site connected throuh openvpn to a pbx. It fail to place a call. line tone remain mute after few seconds tone is busy. The phone receive call from the other site but the call do not store in recent list. A cisco SPA504G in the same network work well instead. In the log i see:
