Abstract
Systems () and methods for a full-duplex call transfer into a half-duplex call. The methods involve: establishing the first full-duplex call between a first communication device () and a second communication device () already engaged in the half-duplex call with at least one third communication device (); and communicating a REFER request message () from the second communication device to the first communication device. The REFER request message includes contact information for redirecting the first communication device to a hybrid application server and token information useful for patching the full-duplex call into the half-duplex call. In response to the REFER request message, the second communication device performs operations to terminate the first full-duplex call and establish a second full-duplex call with the hybrid application server. Thereafter, the hybrid application server performs operations to patch the second full-duplex call into the half-duplex call using the token information.
