DESCRIPTION
proxy/register server specified above. SIP requests sent from other IP addresses will be
ignored.
This field controls how the Device handles fax messages.
Select this if the Device should use G.711 to send fax messages. You have to also select
which operating codec (G.711Mulaw or G.711Alaw) to use for encoding/decoding FAX
data. The peer devices must use the same settings.
Select this if the Device should send fax messages as UDP or TCP/IP packets through IP
networks. This provides better quality, but it may have inter-operability problems. The peer
devices must also use T.38.
Enter the DSCP (DiffServ Code Point) number for SIP message transmissions. The Device
creates Class of Service (CoS) priority tags with this number to SIP traffic that it transmits.
Enter the DSCP (DiffServ Code Point) number for RTP voice transmissions. The Device
creates Class of Service (CoS) priority tags with this number to RTP traffic that it transmits.
Enter the number of seconds your SIP account is registered with the SIP register server
before it is deleted. The Device automatically tries to re-register your SIP account when
one-half of this time has passed. (The SIP register server might have a different expiration.)
Enter the number of seconds the Device waits before it tries again to register the SIP
account, if the first try failed or if there is no response.
Enter the number of seconds the Device lets a SIP session remain idle (without traffic)
before it automatically disconnects the session.
Enter the minimum number of seconds the Device lets a SIP session remain idle (without
traffic) before it automatically disconnects the session. When two SIP devices start a SIP
session, they must agree on an expiration time for idle sessions. This field is the shortest
expiration time that the Device accepts.
Enter the key combinations for certain functions of the SIP phone.
Enter the key combinations that you can enter to place a call to the last number that called
you.
Enter the key combinations that you can enter to activate caller ID for the next call only.
Enter the key combinations that you can enter to deactivate caller ID for the next call only.
Enter the key combinations that you can enter to turn on the call waiting function.
Enter the key combinations that you can enter to turn off the call waiting function.
Enter the key combinations that you can enter to record custom caller ringing tones (the
sound a caller hears before you pick up the phone) and on hold tones (the sound someone
hears when you put their call on hold). IVR stands for Interactive Voice Response.
Enter the key combinations that you can enter to call the phone(s) connected to the Device.
Enter the key combinations that you can enter to transfer a call to another phone.
Enter the key combinations that you can enter to forward all incoming calls to the phone
number you specified in the SIP > SIP Account screen.
Enter the key combinations that you can enter to turn the unconditional call forward
function off.
