现状:

A环境:

Skype for Business Server 2015，前端服务器、持久聊天服务器、边缘服务器。

与MSN、Skype、O365联盟，IM、音频和视频正常。

A与B联盟，A能看B的状态，能发消息给B，B能有回消息，看不到A的状态。

B环境:

Skype for Business Server 2015，前端服务器、持久聊天服务器、边缘服务器。

与MSN、Skype、O365联盟，IM、音频和视频不正常。

A与B联盟，A能看B的状态，能发消息给B，B能有回消息，看不到A的状态。

问题：

Skype for Business Server 2015，前端服务器、持久聊天服务器、边缘服务器。

与MSN、Skype、O365联盟，IM、音频和视频不正常。

A与B联盟，A能看B的状态，能发消息给B，B能有回消息，看不到A的状态。

解决方案：

1. 增加C环境

2. 测试C环境与A、B

3. 发现A与C正常

4. 发现A与B不正常

5. 发现C与B不正常

6. 发现A与B，C与B，问题一样

A与B联盟，A能看B的状态，能发消息给B，B能有回消息，看不到A的状态。

C与B联盟，C能看B的状态，能发消息给B，B能有回消息，看不到C的状态。

问题出在B上，检查B上设置。同。

从以上可以看出，DNS的SRV记录有问题，但：

内部与外部域名一致的时候，与其它SFB联盟，只需要公网上面新建SRV记录才可以。

目前环境，SFB的内部域名，外部域名不一致，这与其它公司的SFB联盟就报上面的问题。

通过查询了好多文档，结果终于找到一个可以参考的。

No Presence for Fedrated partners – Event ID 11

内部SRV:

在内部要为公网的联盟新建SRV记录，才可以!

内外域名不同的SFB环境与其它企业的SFB环境联盟:

内外域名不同的SFB环境与其它企业的o365联盟:

完成!!!

Problem

Came across a deployment with the following 2 issues:-

1. federated partners were showing up as presence unknown

2. unable to call voicemail (hosted in O365)

When trying to send messages to these “unknown” federated partners I got “This message wasn’t sent due to company policy”.

So why did I try to message a contact with a presence status of “unknown? Simply because the federated contact could see my users presence and send me IM’s, I was even able to respond to these IM’s although the presence was still “unknown”.

Troubleshooting

A quick look at the client side logs revealed an error in the presence Subscribe message

Taking a look at the users (client side) local event log I found the same error.

Event ID 11

A SIP request made by Lync failed in an unexpected manner (status code 80ef01f8).

Response Data

504 Server time-out

ms-diagnostics: 1008;reason=”Unable to resolve DNS SRV record“;domain=”ucsorted.com”;dns-srv-result=”NegativeResult”;dns-source=”InternalCache”;source=”access.ucsorted.com”;OriginalPresenceState=”0″;CurrentPresenceState=”0″;MeInsideUser=”No”;ConversationInitiatedBy=”6″;SourceNetwork=”5″;RemotePartyCanDoIM=”Yes”

Clearly there is some issue with either the federation SRV record or resolving the federation SRV record.

Checking the SRV record from the Edge server I can see that this record is not found. Checking the DNS for the Edge server I noticed that the interfaces are pointing to the internal DNS servers.

Solution

We have 2 options here:-

1. Configure the Edge Server to point to a public (external) DNS server where the SRV record for _sipfederationtls._tcp.domain.com is valid (frowned upon by some security folks)

2. Add the SRV record for _sipfederationtls._tcp.domain.com to the internal DNS, making sure that the target FQDN is the Public Access FQDN of the Edge Server.

NOTE

Here is a little reason why you may want to avoid using the common sip.domain.com DNS name for your Edge Servers Access FQDN (only..). Internally the sip.domain.com record was generally configured to resolve to the front end pools, if we now need an internal SRV record for _sipfederationtls._tcp.domain.com then targeting this to sip.domain.com will simply get to the Front End Pool and not to the Federation point at the Access Edge FQDN.
