Hi,
When Avaya Tapi is using an analogue phone I cannot answer the call from the code. However, this is working ok using an IP phone. Is not possible answer a call from an analogue phone?, It is weirs because I if I answer manually from the phone then I can Hold/Unhold the call from the code.
Thanks
