SARVAM UMG supports transporting of SIP messages over TLS. TLS protects SIP signaling against
loss of integrity, confidentiality and replay.
Make sure that you have selected TLS as the SIP Transport option. See
Profile".
•
Configure the SIP UDP Port. This is the port on which SARVAM UMG listens for SIP messages
transported over UDP. This port is also used as the source port for sending SIP messages to the
remote peer. Valid range is 1031 to 65534. Default: 5060.
•
Configure the SIP TCP Port. This is the port on which SARVAM UMG listens for SIP messages
transported over TCP. This port is also used as the source port for sending SIP messages to the
remote peer. Valid range is 1031 to 65534. Default: 5060.
•
Configure the SIP TLS Port. This is the port on which the SARVAM UMG listens for SIP messages
transported over TLS. This port is also used as the source port for sending SIP messages to the
remote peer. Valid range is 1031 to 65534. Default: 5061.
•
Set the duration of the SIP INVITE Timer. This timer defines the time period for which you want
SARVAM UMG to wait for the response from the called party after sending the INVITE message. This
timer starts after sending INVITE message to the called party and stops after receiving the provisional
or the final response or when the call gets disconnected.
On expiry of the timer, SARVAM UMG terminates the call process and gives an error tone to the user.
Valid range is 10 to 200 seconds. Default: 30 seconds.
•
Set the duration of the SIP Provisional Timer. This timer defines the time period for which you want
SARVAM UMG to wait for the final response after receiving the provisional response from the called
party. This timer starts when provisional response is received from the called party and stops after
receiving the final response from the called party or when then call gets disconnected.
On the expiry of the timer, SARVAM UMG terminates the call process and gives error tone to the user.
Valid range is 10 to 200 seconds. Default: 180 seconds.
•
Set the duration of the General Request Timer. This timer defines the time period for which you want
SARVAM UMG to wait for the response to the transaction request. This timer starts when a transaction
is initiated and stops after receiving the response to the request. On expiry of the timer, the SARVAM
UMG clears the transaction. Valid range is 10 to 60 seconds. Default: 20 seconds.

Distinctive Rings
Distinctive Rings are the ringing patterns used for distinguishing between different types of call events.
The distinctive ringing pattern is selected according to Alert-Info header that is included in INVITE message. For
example: Alert-Info <Bellcore-dr2>, or Alert-Info <http://.../Bellcore-dr2>. 'dr2' defines that ringing pattern number 2
will be played on the FXS Port. If the Alert-Info header is missing, the default ring tone will be played on the FXS
Port.
