Project environment:

Deploy a Skype for Business Server 2015 environment at home to achieve:

1. Computer, mobile client, internal and external login, no problem.

two。 Computer, mobile client, internal and external audio and video, no problem.

Project issues:

As a result, Filipino customers depend on the results of the test.

Results:

1. Computer, mobile client, internal and external login, no problem.

two。 Computer, mobile client, internal and external audio and video, no problem for incoming calls, no problem for outgoing calls.

Solution:

Because I have done numerous training and projects before, I am very confident that there will be no problems, but I always have problems of one kind or another, and eventually get rid of the wrong ones. The common questions are as follows:

1. Certificat

If you use a public network certificate, you don't need a guide certificate.

If you use an internal certificate, the computer imports the certificate trust chain to the computer-the trusted certificate authority, and iPhone,iPad installs the root certificate.

two。 Log in

Does Ping sip.i-x-Cloud.com return normal IP?

Does nslookup sip.i-x-Cloud.com return normal IP?

3. Audio, video

a. Public network-computer-SFB- inbound-internal network-SFB- is normal

b. Internal network-computer-SFB- outbound-public network-abnormal SFB-

4. Doubt the influence of NAT

5. Modify the public network IP address of NAT, publish the topology, reinstall the configuration SFBFE01,SFBFE02,SFBFE03, restart, export the topology, copy it to SFBEdge01, reinstall the configuration, and restart.
