Hi Nanang, I just installed program on E51. Even E51 is Symbian FP1, but program is working perfect. However, if I use E61 to call E51 or E51 call E61, they can't hear each other. E51 or E61 can call CISCO 7970 phone without any issue. But when Cisco 7970 call back to E51 or E61. On 7970 side, I only can hear myself (the voice loop itself), no voice on E51 or E61's earpiece. I would appreciate if you can help with this. Have a good weekend, Sen
