Version 5.6 317 November 2008
SIP User's Manual 7. IP Telephony Capabilities
To configure support for emergency calls, configure the parameters below. The device and
the SAS feature are configured independently. If the device and the SAS agent use
different proxies, then the device's proxy server is defined using the 'Use Default Proxy'
parameter, while the SAS proxy agent is defined using the 'Proxy Set' table and
SASProxySet parameter.
EnableSAS = 1
SASLocalSIPUDPPort = (default 5080)
IsProxyUsed = 1
ProxyIP 0 = <external proxy IP address (device)>
ProxyIP 1 = <external proxy IP address (SAS)>
IsRegisterNeeded = 1 (for the device)
IsFallbackUsed = 0
SASRegistrationTime = <expiration time that SAS returns in the 200 OK to REGISTER
in Emergency mode> (default 20)
SASDefaultGatewayIP = < SAS gateway IP address>
SASProxySet = 1
7.2 Configuring the DTMF Transport Types
You can control the way DTMF digits are transported over the IP network to the remote
endpoint, by using one of the following modes:
Using INFO message according to Nortel IETF draft: DTMF digits are carried to the
remote side in INFO messages. To enable this mode, define the following:
RxDTMFOption = 0 (ini file); 'Declare RFC 2833 in SDP' field = 'No' (Web
interface -- refer to ''DTMF & Dialing Parameters'' on page 125)
TxDTMFO
ption = 1 (ini file); '1
st
to 5
th
Tx DTMF Option' field = 'INFO (Nortel)' (Web
interface -- refer to ''DTMF & Dialing Parameters'' on page 125)
Note that in this mod
e, DTMF digits are erased from the audio stream
[DTMFTransportType is automatically set to 0 ('DTMF Transport Type' field = 'DTMF
Mute' -- Web interface)].
Using INFO message according to Cisco’s mode: DTMF digits are carried to the
remote side in INFO messages. To enable this mode, define the following:
RxDTMFOption = 0 (ini file); 'Declare RFC 2833 in SDP' field = 'No' (Web
interface -- refer to ''DTMF & Dialing Parameters'' on page 125)
TxDTMFO
ption = 3 (ini file); '1

th
Tx DTMF Option' field = 'INFO (Cisco)' (Web
interface -- refer to ''DTMF & Dialing Parameters'' on page 125)
Note that in this mod
e, DTMF digits are erased from the audio stream
(DTMFTransportType is automatically set to 0 ('DTMF Transport Type' field = 'DTMF
Mute' -- Web interface)].
Using NOTIFY messages according to <draft-mahy-sipping-signaled-digits-
01.txt>: DTMF digits are carried to the remote side using NOTIFY messages. To
enable this mode, define the following:
RxDTMFOption = 0 (ini file); 'Declare RFC 2833 in SDP' field = 'No' (Web
interface -- refer to ''DTMF & Dialing Parameters'' on page 125)
