If only a
single SIP Proxy Server is needed for outbound call routing from the Call
Server, choose the SIP Proxy configuration when configuring the SIP Service. In
the Unified CVP Operations Console Server, configure the following:
Under the
Call Server SIP Service settings, configure the following:
-
Enable Outbound
Proxy = True
-
Use DNS SRV type
query = False
-
Outbound Proxy
Host = SIP Proxy Server configured above
When using
multiple SIP Proxy Servers for outbound redundancy from the Call Server,
configure the SIP Proxy with a DNS name and configure DNS SRV records in order
to reach the SIP Proxy Servers. The DNS SRV records can exist on an external
DNS Server, or they can be configured in a local DNS SRV record on each CVP
server. In the OAMP Console, configure the following:
Under SIP
Service configuration, configure the following:
-
Enable Outbound
Proxy = True
-
Use DNS SRV type
query = True
The DNS SRV record should then be configured with the list of SIP
Proxy Servers.
To
configure the Local DNS SRV record on each server, under the SIP service
configuration, check
Resolve SRV
records locally.
To use a
server group for redundant Proxy Servers:
-
Select
resolve SRV
records locally and enter the name of the server group for the outbound
proxy domain name.
-
Under
System >
Server Groups, create a new server group with two proxy servers that have
priority 1 and 2.
-
Deploy the
server group configuration to the Call Server.
