Mediant 1000B Gateway & E-SBC
Interface would represent a specific Layer-3 network (IP PBX, SIP Trunk, or far-end users)
in your environment. The following figure provides an example of such a deployment:
Figure 17-6: Deployment using a Single SRD
Note:
• It is recommended to use a single-SRD configuration topology, unless you are
deploying the device in a multi-tenant environment, in which case multiple SRDs
are required.
• Each SIP Interface, Proxy Set, and IP Group can be associated with only one
SRD.
• If you have upgraded your device to Version 7.0 and your device was configured
with multiple SRDs but not operating in a multi-tenant environment, it is
recommended to gradually change your configuration to a single SRD topology.
• If you upgrade the device from an earlier release to Version 7.0, your previous
SRD configuration is fully preserved regarding functionality. The same number of
SRDs is maintained, but the configuration elements are changed to reflect the
configuration topology of Version 7.0. Below are the main changes in configuration
topology when upgrading to Version 7.0:
√ The SIP Interface replaces the associated SRD in several tables (due to
support for multiple SIP Interfaces per SRD).
√ Some fields in the SRDs table were duplicated or moved to the SIP Interfaces
table.
√ Indices used for associating configuration entities in tables are changed to row
pointers (using the entity's name).
√ Some tables are now associated (mandatory) with an SRD (SIP Interface, IP
Group, Proxy Set, and Classification).
√ Some fields used for associating configuration entities in tables now have a
value of Any to distinguish between Any and None (deleted entity or not
associated).
