the IP Address of the WAN Port to the DNS Server in the network.
RTP Mode
• Click RTP Mode to expand.
• RTP Mode: Select the desired RTP mode using which you want PRASAR UCS to route speech in SIP to
SIP calls.
You can select from the following:
• Transcoding: When this option is selected, RTP packets will be routed using Vocoder channels
63
for
SIP to SIP calls. SIP users (Extended SIP Clients and Standard SIP Clients) will be able to access all
the features of PRASAR UCS. This option uses two Vocoder channels for SIP to SIP calls. Thus the
maximum number of SIP to SIP calls per system is equal to the number of Vocoder channels divide by
2.
• RTP Relay: When this option is selected, RTP packets will be routed without using Vocoder channels
for SIP to SIP calls.The System will use Vocoder channels for some features and Standard SIP Clients
will be able to use limited features of PRASAR UCS. Refer to “PRASAR UCS Features supported with
RTP/Direct RTP” for more details.
• Direct RTP: When this option is selected, no Vocoder channel will be used for SIP to SIP calls and
RTP packets will be sent to and fro directly between SIP end points. If transfer of RTP packets is not
possible between SIP end points, system will use RTP Relay as the fallback option. System will use
Vocoder channels for some features and Standard SIP Clients will be able to use limited features of
PRASAR UCS. Refer to “PRASAR UCS Features supported with RTP/Direct RTP” for more details.
• Direct RTP is not supported on SIP Trunks and MATRIX VARTA ADR100/AMP100/WIN200, therefore
the system will use RTP Relay.
• If RTP Relay or Direct RTP is selected, maximum 550 Audio calls or 50 Video calls are supported in
PRASAR UCS.
• If you change the RTP Mode, the system will release all ongoing calls.
• In RTP Mode Relay/DRTP, System will generate max 300 unsecured MoH streams (without SRTP) or
max 100 SRTP MOH streams simultaneously.
• FAX is not supported when Transcoding is set as the RTP Mode.
• Video calls will use RTP Relay even when Transcoding is set as the RTP Mode.
• MoH Vocoder Preference: If RTP Mode is set as RTP Relay or Direct RTP, the system will play the MoH
stored in the Vocoder module when the system holds any SIP end point. The MoH is played as per the
configured MoH Vocoder Preference.
63. The number of Vocoder channels that will be supported would be as per the license you purchase.
