The Call-Transfer Recall feature in Cisco Unified CME 4.3 and later versions returns a transferred call to the phone that initiated the transfer if the destination is busy or does not answer. After a phone user completes a transfer to a directory number on a local phone, if the transfer-to party does not answer before the configured recall timer expires, the call is directed back to the transferor phone. The message "Transfer Recall From xxxx" displays on the transferor phone.
The transfer-to directory number cannot have Call Forward Busy enabled and cannot be a member of any hunt group. If the transfer-to directory number has Call Forward No Answer (CFNA) enabled, Cisco Unified CME recalls the call only if the transfer-recall timeout is set to less than the CFNA timeout. If the transfer-recall timeout is set to more than the CFNA timeout, the call is forwarded to the CFNA target number after the transfer-to party does not answer.
If the transferor phone is busy, Cisco Unified CME attempts the recall again after a 15-second retry-timer expires. Cisco Unified CME attempts a recall up to three times. If the transferor phone remains busy, the call is disconnected after the third recall attempt.
The transferor phone and transfer-to phone must be registered to the same Cisco Unified CME, however the transferee phone can be remote.
