SIP Server Applications on Embedded
Platforms
Presented by Amir Zmora

2. Agenda
Modern SoHo Communications
SIP Server Functionality From Voice to Video -
Use Cases and Examples
RADVISION SIP Server Framework

3. Modern SoHo communications
POTS phone
IP-phone
Video Phone
Soft Phone
Fax
IM/Presence
IP
Operator?

4. What is the question mark
How do you connect rich SoHo communications
To IP Telephony Service Provider (ITSP)
With low cost
With extended multimedia functionality
With internal SoHo communication (PBX functionality)
In a secured way
?

5. Embedded SIP server applications
Growing demand
SIP Server
Software
Electronic Board
IAD
RGW Key-System
small PBX
Set-top box

aware FW
SBC

6. SIP servers on embedded systems, Why?
Product price competition
Lower BOM on mass production
Product performance density
Dedicated HW
Using DSPs
HW acceleration tasks
Product usability
Minimal Service
Product size
Part of a bigger system (racks/blades…)

7. Challenges developing SIP servers on
Embedded systems
Porting to embedded OS:
•MV Linux, ucLinux, Android…
•OSE
•vxWorks
Performance requirements:
•Footprint
•Memory consumption
•Transaction speed
Media processing:
•Transcoding
•Conferencing
•Recording
•Announcements
Application flexibility:
•Interface to other parts of the system (blades/racks/servers)
•Interfaces to HW modules
•Proprietary product features
Signaling feature richness:
•Call control
•Presence/IM
•FW/NAT traversal
Development environment:
•programming language
•IDE
•Testing and debugging
Media quality:
•Video quality
•Voice quality

9. RGW/IAD functionality evolution
Classical RGW/IAD functionality
is quite basic

10. WAN

11. RGW/IAD functionality evolution
Modern RGW/IAD functionality is something
else…
