How do we make it work? Asterisk Server installed and configured using Ubuntu
SIP.conf Extensions.conf
Configurations in SBCSystem
Steering pool
Session agent
Realm
Local policy
Sip interfaceNetwork interface
Physical Interface
SIP TRACES
RTP TRACES
Troubleshooting Asterisk
› Some sip files went missing: qmail: purge qmail› Port forwarding issue
SBC
› NAT-mode: None public› Registration caching disabled
Summary Installed and configured Asterisk Server
successfully Tested the working of Asterisk by calling
from one SIP phone to other Successfully configured SBC Tested the SBC by making calls between
Android phones Video conferencing feature could not be
implemented as our SBC model requires appropriate licenses
Tried including Google trunk feature into our product but GUI issue held us on it
Tried to integrate the presence server feature along with SBC calls – again routing issues prevailed
Overall, our product has been successfully made to work
What more? NAT Traversal
Media Transcoding
Video Calling
Lawful Interception
And much more……..
Questions???
Thank you!
