SIP Options

Sets the SIP parameter values.

 

SIP Option

Item

Description

Gateway Call ID

Sets the caller ID to account.

DIL Number

If the dial digits is not included in the received call, this option specifies the number to which the call is made to be received.

Signal Port

Sets the UDP port number for signaling.

Caller ID Type

Sets the caller ID type to send to the receiving side when sending a call. It can be displayed only if it has the same type as the caller sent.

MFR Alloc

When an incoming VoIP trunk call is sent directly to other trunk without passing via a station, the DTMF signal is detected which enters from that trunk. At this time, this option sets whether to assign the DTMF Receiver.

Real Ringback Tone

When calling with a VOIP trunk, this option sets whether to have a virtual tone heard or have a ring back tone received from the opposite party heard.

RE-Route Time (sec)

When sending a VOIP trunk call, if there is no answer from the opposite party within this time, it is processed as fail. In case of the LCR, this option specifies the time to call the next group.

Gateway Allow

In case that this option is set to ENABLE, when receiving a H.323 call, if the calling side IP address is not registered in ¡®5.2.5 VoIP Routing IP Address¡¯, the call is not received.

UDP Trunk Port

Sets the UDP port number when the opposite party of the trunk is also a trunk.

UDP Phone Port

Sets the UDP port number when the opposite party of the phone is also a phone.

T1 Time (100ms)

When using an unreliable transmission protocol such as UDP, if there is no answer after transmitting a call, it is retransmitted. The T1 Time is the first retransmission interval defined in the RFC2543.

T2 Time (100ms)

Maximum retransmission interval defined in the RFC2542.

General Ring Time (100 ms)

In an unreliable transmission protocol, the server cannot ensure that the client has received the last answer after it sent it. In this case, until the retransmission that the server requested is received, it must retransmit the answer during this time.

For example, it is the time to wait after sending a 200 OK message for an INFO message.

 

Item

Description

Invite Ring Time (100 ms)

In an unreliable transmission protocol, the client cannot ensure whether the server has received the ACK message after the client sent an ACK for an INVITE Final Response. At this time, this is the time to wait after sending an ACK for the Final Response.

Provisional Time (100 ms)

When a provision response is received, this is the time to wait before the user agent ends the timer.

Inverse Response Time (100 ms)

This is the time for the user agent to wait before sending a cancel for an Invite Request.

T4 Time (100 ms)

This is defined and used for several uses in the RFC 2543.

For example, in an unreliable transmission protocol, one of them is the time to wait after the USA (User Agent Server) receives an ACK message.

CLIP Table

Sets the UDP port number for signaling.

Incoming Mode

When a VoIP call is received, this option sets whether to use the received Called Party Number as it is or to follow the ¡®3.2.3 DID Ringing¡¯ or to follow the receiving location for trunks specified in ¡®3.2.1 Trunk Ringing¡¯. When a VOIP call is received, this option sets whether to use the received Called Party Number as it is or to follow the ¡®3.2.3 DID Ringing¡¯ or to follow the receiving location for trunks specified in ¡®3.2.1 Trunk Ringing¡¯.

General Response Time (100 ms)

This is the time for the user agent to wait before sending a cancel for a General Request.

Request Retry Time (100 ms)

This is the time for the user agent to wait until it receives a Final Response after sending a General Request.

Server IP Address

Sets the IP address of the SIP server.

Registration per User

When using the SIP server, if this item is set to Enable, you can register it for each user. If set to Disable, you can registers a representative number to it.

Gateway Enable

Sets whether to use the SIP server.

Server Port

Sets the port number of the SIP server.

Regist Trunk Number

Sets the representative number to register in the SIP server.

Proxy Domain Name

Sets the domain name for authentication when using the SIP server.

User ID

Sets the user ID for authentication when using the SIP server.

Regist Password

Sets the password to use when authentication is needed to register a number to the SIP Server, This is to used when registering the representative number.

Regist Expire (sec)

This expire time value is needed to register a number to the SIP server periodically. Generally, a value given by the SIP server is used. We recommend using the default value.

 

Item

Description

Session Timer

This the timer value to use when sending and receiving a message periodically to preserve a session after it is set up. Whether to use the session timer is predefined for each SIP server. We recommend using the default value.

Session Vendor

This option is used to discriminate the slightly different operations of each server. We recommend using the default value.

Regist Status

Displays whether the terminal is registered to the SIP server.

SIP Station Expire Time (sec)

Sets the registration expire time of the SIP station terminal.

We recommend using the default value.

SIP Peering

When making a call in interoperation with the SIP server, usually, the SIP server IP address is used in the From/To header. But, this option is used when you want use the IP address of the terminal for a specific SIP server.

Codec Auto Negotiation

Sets whether to set the voice codec automatically.

TLS Port

This is the port specified to use the TLS.

Use TLS

Sets whether to use the TLS when performing SIP signaling.

Proxy Server Address

Sets the domain name or IP address of the SIP server.

If a domain name is entered in this option, the DNS query is executed and, through this, the IP address of the SIP server is obtained.

Alter Proxy IP Address

In case that the proxy address is specified to be an IP address type, this option sets the alternative proxy IP address to replace when the specified SIP server fails.

DNS Server1 IP Address

When executing a DNS Query using a domain name, this option sets the IP address of the name server that gives the IP address of the SIP server.

DNS Server2 IP Address

Set the alternate name server to use when the name server specified in the DNS Server1 IP Address field fails.
