Now a days SIP service are growing and the service provider are providing SIP as a service.These services can be terminated for a enterprise on a SBC/CUBE .
The CUBE has many benefit over traditional TDM circuit etc.
CUBE can be deployed in two mode:
The CUBE has many benefit over traditional TDM circuit etc.
The benefit are
Interoperability : SIP is a protocol supported by many vendor hence these can be deployed with different SIP solution
Demarcation Point : CUBE can be used as a demarcation point between PSTN and enterprise network
Encryption and security is also a part of CUBE,you can use CUBE to hide the IP address of the CUCM
To achieve the redundancy the SIP has more flexibility compared to Traditional Telephony.
CUBE can be deployed in two mode:
Media flow around : in case of media flow around the CUBE doesn't comes into media path
Media flow through : In case of media flow through the CUBE comes into media path
The command can be configured under dial-peer config using the command :
media flow-through|flow-around
CUBE can be used for media codec negotiation as well when the service provider link is terminated on the cube.
You can configure the media negotiation mode by configuring the below command under dial-peer
codec transparent
The above command define that the CUBE will not be part of any codec negotiation . if this command is not there then CUBE take part in codec negotiation
apart from then you need to configure allow-connection under voice service voip command
You can verify SIP calls in the CUBE using the command
show sip calls
show voice call status
show voip rtp connection
show call active voice
debug command used to debug dial peer
debug dialper voice inout
