LABEL

DESCRIPTION

SIP Service Provider Selection

Service Provider 
Selection

Select the SIP service provider profile you want to use for the SIP account you configure 
in this screen. If you change this field, the screen automatically refreshes. 

General

SIP Service 
Provider

Select this if you want the LTE Device to use this SIP provider. Clear it if you do not want 
the LTE Device to use this SIP provider.

SIP Service 
Provider Name

Enter the name of your SIP service provider. 

SIP Local Port

Enter the LTE Device’s listening port number, if your VoIP service provider gave you one. 
Otherwise, keep the default value.

Main SIP Server 
Address

Enter the IP address or domain name of the SIP server provided by your VoIP service 
provider. You can use up to 95 printable ASCII characters. It does not matter whether the 
SIP server is a proxy, redirect or register server.

SIP Server Port

Enter the SIP server’s listening port number, if your VoIP service provider gave you one. 
Otherwise, keep the default value.

REGISTER Server 
Address

Enter the IP address or domain name of the SIP register server, if your VoIP service 
provider gave you one. Otherwise, enter the same address you entered in the SIP Server 
Address field. You can use up to 95 printable ASCII characters.

REGISTER Server 
Port

Enter the SIP register server’s listening port number, if your VoIP service provider gave 
you one. Otherwise, enter the same port number you entered in the SIP Server Port 
field.

SIP Service 
Domain

Enter the SIP service domain name. In the full SIP URI, this is the part after the @ 
symbol.  You can use up to 127 printable ASCII Extended set characters.

RFC Support

PRACK (RFC 
3262)

RFC 3262 defines a mechanism to provide reliable transmission of SIP provisional 
response messages, which convey information on the processing progress of the request. 
This uses the option tag 100rel and the Provisional Response ACKnowledgement (PRACK) 
method.

Select Supported or Required to have the LTE Device include a SIP Require/Supported 
header field with the option tag 100rel in all INVITE   requests. When the LTE Device 
receives a SIP response message indicating that the phone it called is ringing, the LTE 
Device sends a PRACK message to have both sides confirm the message is received. 

If you select Supported, the peer device supports the option tag 100rel to send 
provisional responses reliably.

If you select Required, the peer device requires the option tag 100rel to send provisional 
responses reliably.

Select Disabled to turn off this function. 

DNS SRV Enabled 
(RFC 3263)

Select this option to have the LTE Device use DNS procedures to resolve the SIP domain 
and find the SIP server’s IP address, port number and supported transport protocol(s).

The LTE Device first uses DNS Name Authority Pointer (NAPTR) records to determine the 
transport protocols supported by the SIP server. It then performs DNS Service (SRV) 
query to determine the port number for the protocol. The LTE Device resolves the SIP 
server’s IP address by a standard DNS address record lookup.

Session Timer 
(RFC 4028)

Select this to have the LTE Device support RFC 4028.

This makes sure that SIP sessions do not hang and the SIP line can always be available 
for use.
