• Outbound Proxy Port
The proxy port on the proxy server to which the OMM sends all
SIP messages. Optional.
• Explicit MWI Subscription
Some Media Server such as the Asterisk support Message
Waiting Indication (MWI) based on /15/. A MWI icon will be
presented on an Aastra DECT 142 Handset / Aastra 142d if the
user has received a voice message on his voice box which is
supported by the Media Server. If Explicit MWI Subscription is
enabled the OMM sends explicit for each PP a MWI
Subscription message to the Proxy or Outbound Proxy Server.
• User agent info
If enabled the OMM send out information about his version
inside the SIP headers User-Agent/Server.
• Send dial terminator
If enabled the OMM doesn’t use the ‘#’ character to detect the
completeness of dial input from a user. Instead the OMM waits 4
seconds for additional input after the user has pressed a dial
digit. If enabled the ‘#’ character can be part of dial information.
• Registration retry timer
Specifies the time, in seconds, that the OMM waits between
registration attempts when the registration is rejected by the
registrar.
• Transaction timer
The amount of time in milliseconds that the OMM allows a
callserver (proxy/registrar) to respond to SIP messages that it
sends. If the OMM does not receive a response in the amount of
time designated for this parameter, the OMM assumes the
message as timed out. In this case the callserver is recorded to
the blacklist. Valid values are 4000 to 64000. Default is 4000.
• Blacklist time out
The amount of time in minutes a unreachable callserver stay in
the blacklist. Valid values are 0 to 1440. Default is 5.
• RTP Port Base
Each RFP needs a continuous port area of 68 UDP ports for
RTP voice streaming. The RTP Port Base is the start port
number of that area. Default is 16320.
• Preferred Codec 1 – 5
Specifies a customized codec preference list which allows you
to use the preferred Codecs. The Codec 1 has the highest and
Codec 5 the lowest priority.

not.
