Is this a new installation or has it been working previously? Could you tell me where the call was transferred to, is it locally to another IP phone or to a phone located in the PSTN? Are you using H.323 mode or MGCP mode?
Only hookflash "relay" is supported in H.323 mode, meaning if you call from an FXS port to an FXO port a hookflash will be sent out on the FXO port in case the connected device supports it. IOS does not include support for conferencing and transfer by itself, so you cannot do these things in H.323 mode. They are supported in MGCP mode because CallManager handles it.
