hookflash: Hookflash is either a button on the phone to simulate the quick offhook/ onhook/offhook cycle or the actual cycle itself. Hookflash can be used as the trigger event for switching to call waiting or three way call conferencing.

onhooksignaling: On-hook signaling indicates the phone can accept any features or signals that only enabled while the phone is on-hook.

alwaysoffhook: When an incoming call is received the receiver of the call is notified by a tone of an incoming call; the hookflash trigger switches the subscriber between the ongoing call and the incoming call. The original call is placed on hold.

plar: PLAR connection.

callwait: When an incoming call is received the receiver of the call is notified by a tone of an incoming call; the hookflash trigger switches the subscriber between the ongoing call and the incoming call. The original call is placed on hold.

calltransfer: When the call transfer feature is added to hookflash, the system supports transferring calls. The hookflash trigger during an ongoing call gives the subscriber a secondary dialtone and will accept dialing. The original call is on hold until another hookflash.

Preferred Codec The preferred voice codec to be used for this subscriber.
G711 Fallback Indicates whether a subscriber may consume bandwidth by switching to g711, when a fax, modem, b-channel data session is detected.

G726 Byte Order

Indicates the byte order to be used for g.726 voice coding. Cisco uses little endian byte order. The g.726 standard calls for big endian byte order.

T38 Fax Type

T.38 fax service enables fax messages to be transported across VoIP networks between G3 fax terminals. When configured for SIP or SIP PLAR and T.38, the system provides a T.38 fax relay service between two devices configured for the same VoIP protocol. If one side of the T.38 connection is not configured for T.38 support, the fax call reverts to g.711 pass through when this option is configured. Otherwise, the fax may not go through.

Note: When using T.38 fax, be sure that all the devices on the network which are involved in the T.38 transmission/reception are correctly configured for T.38 fax service.

t38udptl options enables T.38 service using UDP IP packets. The t38none option disables the service.
