dtmf_outofband—(Optional) Whether to generate the out-of-band signaling

SIP IP phone supports out-of-bound signaling via the AVT tone method.
Valid values are:
–

(and disable in-band DTMF signaling), otherwise, do not generate
DTMF digits out-of-band.

disables in-band DTMF signaling.
The default is avt.
•

is 96 to 127. If the value specified exceeds 127, the phone will default to 101.
•

timer for SIP messages. The valid value is any positive integer. The default
is 500.
•
timer_t2—(Optional) Highest value (in milliseconds) of the retransmission
timer for SIP messages. The valid value is any positive integer greater than
timer_t1. The default is 4000.
•
timer_invite_expires—(Optional) The amount of time, in seconds, after
which a SIP INVITE will expire. This value is used in the Expire header field.
The valid value is any positive number, however, we recommend 180 seconds.
