Hi Surender,

To use an external HSS you'll need to set the following settings in 
/etc/clearwater/shared_config

hss_hostname=<address of your HSS>
hss_realm=<realm your HSS is located in>
hss_port=<port of your HSS's Cx interface>

Both hss_hostname and hss_realm are optional. If a realm is configured, 
homestead will try NAPTR/SRV resolution on the realm to find and connect to (2 
by default) diameter peers in the realm.
If a hostname is also configured, this will be used in the Destination-Host 
field on the diameter messages, so that the messages will be routed to that 
host.
If just a hostname is configured, homestead will just attempt to create and 
maintain a single connection to that host.

You can find more information on this at 
http://clearwater.readthedocs.io/en/latest/External_HSS_Integration.html, and 
you may also find 
http://clearwater.readthedocs.io/en/latest/OpenIMSCore_HSS_Integration.html 
useful.

For your other queries:

1. You can configure subscribers to use an application server that provides 
these functions by setting their IFCs in the HSS. You can use the MMTel 
application server built into Clearwater for this - see the details at 
http://clearwater.readthedocs.io/en/latest/OpenIMSCore_HSS_Integration.html#adding-the-mmtel-application-server
 for more information.

2. The key restrictions of the all-in-one solutions are:
* hard-coded realm - the all-in-one image uses a hard-coded realm of 
example.com so your SIP URI might be sip:[email protected] - by default, 
SIP uses this realm for routing but example.com won't resolve to your host so 
you need to configure an outbound proxy on all your SIP clients
* performance - since all software runs on a single virtual machine, 
performance is significantly lower than even the smallest scale deployment
* scalability - there is no option to scale up and add more virtual machines to 
boost capacity - for this, you must create a normal deployment
* fault-tolerance - since everything runs on a single virtual machine, if that 
virtual machine fails, the service as a whole fails.

3. I didn't understand this question. What's the 'other DNS'?

I having some below query..


1)      Can we provision the basic supplementary  service (CF Service, Three 
Party, Call-Transfer , Call park  etc .) in open HSS.
