5-1 SIP

Figure 5-1 SIP

Parameter Description:

 SIP Hold Type: SIP on hold message sending method.

- Send Only: Set the SDP media to sendonly when send an on-hold
SIP message.

- 0.0.0.0: Set the SDP connection to 0.0.0.0 when send an on-hold
SIP message.

- Inactive: Set the SDP media to inactive when send an on-hold SIP
message.

 SIP Compact Form: Enable SIP compact form or not. When en able

this featur e, the connected SIP proxy is requ ired to support compac t
form.

 Session Refresher: Who will send dialog keep alive message

(re-invite or upd a te).

 UAC: User Agent Client will do the r e fresh (defa ult setting)
 UAS: User Agent Server will do the refresh
 SIP T1 (msec): T1 determines several timers as defined in

RFC3261. For exa m ple, when an unreliable trans port protocol is
used, a Client Invite transaction retransmits req uests at an interval
that start at T1 seconds and doubles after every retransmission. A
Client General transa ction retransmits reques ts at an interv a l that
starts at T1 and doubles until it reaches T2. (Default Value: 500ms)
**

37

 SIP T2 (msec): Determines the maximum re transmission interval

as defined in RFC3261. For example, when an unreliable trans port
protocol is used, genera l r eq uests are retransmitted at a n interval
which starts at T1 and doubles until reaches T2 . If a provisiona l
response is rec eived, retra nsmission continu e but at an interv al of T2.
(Default Value: 4000ms) **

 SIP T4 (msec): T4 represen ts the amount of time the network

takes to clear message between client and server transactions as
defined in RFC3261. For example, when work in g with an unreliable
transport p rotocol, T4 determines the time that UAS waits after
receiving an AC K m es s a ge an d bef or e term inating the trans a c tion .
(Default Value: 5000) **

 Invite Linger Timer: After sending an ACK for an INVITE final

response, a client cannot be sure that the serv er has received the
ACK message. Th e client should be able t o retransmit the ACK upon
receiving retr a nsmissions of the final resp onse for this timer. T his
timer is also u sed when a 2xx respon se is sent for an incomin g Invite.
In this case, the ACK is not part of the Invite transaction.

 General Linger Timer: After a UAS sends a final response, the UAS

cannot be sure tha t th e c lien t has received the respon s e m es s a ge.
The UAS should be able to retransmit the response upon receiving
retransmiss ions of the request based on this tim er .

 Ca nc el General No Response Ti me (msec): When sending a

CANCEL request on a General transaction, the User Agent waits
cancel General No Response Timer millisecond s be fore timeout
termination if there is no response for the cancelled
transaction(Default Value: 10000ms).**

 General Request Timeout Timer (msec): After sending a

General reques t, th e U s er A gent waits for a final response general
Request Timeout Timer milliseconds be fore timeout termination (in
this time the User Agent retransmits the requ est every T1,
2*T1,…T2,…milliseconds)**

 Ca nc el Invite No Response Time r (msec): When sending a

CANCEL request on a n Invite request, the User Agent waits this
timer before time out termination if there is no response for the
cancelled transaction.

 Provisional Timer (msec): The provisionalTimer is set when

receiving a pr ovisional res p onse on an INVITE transaction. The
transac tion will stop retransmissions of the IN VITE request and will
wait for a final response until the provisionTimer expires . If you set
the provision T imer to 0 , no tim er is s et. Th e INVI TE tr an sa ction will
wait indef initely for the final response.

 First Response Timer (msec): When sending a request out, the

User Agent waits this timer for any r esponse receiv ed from UAS. If
timer is expired and n o any SIP mess age is received, t he User Agent

38

will think th e request is failed. The default is 5 s e c onds.

 MWI Subscript Expires (sec): Y ou can Enable or Disable the MWI

subscribe. The default is 600 sec. If a new voice mail is arrived, the
stutter tone will be used inste a d of regular dial tone. This feature is
dedicate to FXS only.

 L ine Congesti on Code: when callee's end system was contacted

successfully but the callee is busy an d does n ot wish to ta ke the call
at this time, the system wills response the code, default is 600.

(FXO use)

 SIP-Info Flash Mode: when you enable the feature, sys tem will

make flash key to send SIP message by sip-info.

CH9 Route Plan

The core of WellGate 2424s is the routing policy . The policy is base d on
incoming call type/target, length and pre fix to determinate the
outgoing call process. For VOIP incoming call, it can send to FXS
interface and vice versa.

For FX S interface, it could b e routed to VOIP a nd vice versa. Y ou can ignore the
routing plan if you don’t need it for FXS interface.
