JUNOS OS 10.4 Release Notes

SRX Series MGW. In this case, the SRX Series MGW might retransmit the message,
incurring unnecessary processing and adding to the network load.
When you configure peer call server information, you can disable transmission of the
registration message to the peer call server to avoid these problems.
NOTE: Disabling transmission of the SRX Series MGW registration to the
peer call server does not disable registration of an FXS station to the SRX
Series MGW on the device running Integrated Convergence Services.

Disabling SIP registration to the proxy server—By default, Integrated Convergence
Services SIP trunks register to the SIP service provider's peer proxy server. For some
SIP networks, the peer proxy server is informed about all SIP trunks that communicate
with it. In such network environments, the SIP trunk does not need to send a REGISTER
message to the peer proxy server. To do so would increase network load unnecessarily.
To accommodate these network environments, you can configure the SIP trunk not
to register to the peer proxy server.

DSCP marking for RTP packets generated by SRX Series Integrated Convergence
Services—Configure DSCP marking to set the desired DSCP bits for Real-Time Transport
Protocol (RTP) packets generated by SRX Series Integrated Convergence Services.
Differentiated Services code point (DSCP) bits are the 6-bit bitmap in the IP header
used by devices to decide the forwarding priority of packet routing. When the DSCP
bits of RTP packets generated by Integrated Convergence Services are configured, the
downstream device can then classify the RTP packets and direct them to a higher
priority queue in order to achieve better voice quality when packet traffic is congested.
Juniper Networks devices provide classification, priority queuing, and other kinds of
class-of-service (CoS) configuration under the CoS configuration hierarchy.
Note that the Integrated Convergence Services DSCP marking feature marks only RTP
packets of calls that it terminates, which include calls to peer call servers and to peer
proxy servers that provide SIP trunks. If a call is not terminated by Integrated
Convergence Services, then DSCP marking does not apply.
To configure the DSCP marking bitmap for calls terminated by Integrated Convergence
Services and the address of the peer call server or peer proxy server to which these
calls are routed, use the
media-policy
hierarchy level.
set services convergence-service service-class < name > dscp < bitmap >
set services convergence-service service-class media-policy < name > term < term-name
> from peer-address [< addresses >]
set services convergence-service service-class media-policy < name > term then
service-class < name >
