Hello Team, i have a trunk CUCM to SFB 2015 where skype can call Cisco extension but Cisco cannot call Skype extensions, i get the error 503 service unavailable on the skype server. So far i downloaded and installed the latest SFB update that did not fix the issue. here are some logs of Cisco to SFB fetch from Skype: TL_INFO(TF_PROTOCOL) [SFB\PR-VM-SFB-01]1594.3D3C::07/01/2019-11:43:13.941.00002000 (S4,SipMessage.DataLoggingHelper:sipmessage.cs(801)) [431143657] <<<<<<<<<<<<Incoming SipMessage c=[<SipTcpConnection_5291CE>], 10.10.30.23:5068<-10.10.60.250:35810 INVITE sip:820993@10.10.30.23:5068 SIP/2.0 FROM: "AMBOZOO" <sip:25006@10.10.60.250>;tag=40478~bb16990c-bb8d-474d-e339-4cb6bd7d93e7-23478979 TO: <sip:820993@10.10.30.23> CSEQ: 101 INVITE CALL-ID: ff535980-d191edc8-41b-fa3c0a0a@10.10.60.250 MAX-FORWARDS: 69 VIA: SIP/2.0/TCP 10.10.60.250:5060;branch=z9hG4bK41e3a437828 ALLOW-EVENTS: presence CONTACT: <sip:25006@10.10.60.250:5060;transport=tcp>;+u.sip!devicename.ccm.cisco.com="CSFAMBOZOO";bfcp CONTENT-LENGTH: 202 DATE: Mon, 01 Jul 2019 11:26:00 GMT EXPIRES: 180 SUPPORTED: timer,resource-priority,replaces SUPPORTED: X-cisco-srtp-fallback,X-cisco-original-called USER-AGENT: Cisco-CUCM11.0 CONTENT-TYPE: application/sdp ALLOW: INVITE, OPTIONS, INFO, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIFY P-ASSERTED-IDENTITY: "AMBOZOO" <sip:25006@10.10.60.250> Min-SE: 1800 Session-ID: 00001cc400105000a0001002b529e1f4;remote=00000000000000000000000000000000 Cisco-Guid: 4283652480-0000065536-0000000002-4198238730 Session-Expires: 1800 Remote-Party-ID: "AMBOZOO" <sip:25006@10.10.60.250>;party=calling;screen=yes;privacy=off v=0 o=CiscoSystemsCCM-SIP 40478 1 IN IP4 10.10.60.250 s=SIP Call c=IN IP4 10.123.123.10 t=0 0 m=audio 16386 RTP/AVP 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 ------------EndOfIncoming SipMessage TL_INFO(TF_PROTOCOL) [SFB\PR-VM-SFB-01]1594.2FE8::07/01/2019-11:43:13.942.00002001 (S4,SipMessage.DataLoggingHelper:sipmessage.cs(801)) [431143657] >>>>>>>>>>>>Outgoing SipMessage c=[<SipTcpConnection_5291CE>], 10.10.30.23:5068->10.10.60.250:35810 SIP/2.0 100 Trying FROM: "AMBOZOO"<sip:25006@10.10.60.250>;tag=40478~bb16990c-bb8d-474d-e339-4cb6bd7d93e7-23478979 TO: <sip:820993@10.10.30.23> CSEQ: 101 INVITE CALL-ID: ff535980-d191edc8-41b-fa3c0a0a@10.10.60.250 VIA: SIP/2.0/TCP 10.10.60.250:5060;branch=z9hG4bK41e3a437828 CONTENT-LENGTH: 0 ------------EndOfOutgoing SipMessage TL_INFO(TF_PROTOCOL) [SFB\PR-VM-SFB-01]1594.36B0::07/01/2019-11:43:13.953.00002005 (S4,SipMessage.DataLoggingHelper:sipmessage.cs(801)) [431143657] >>>>>>>>>>>>Outgoing SipMessage c=[<SipTcpConnection_5291CE>], 10.10.30.23:5068->10.10.60.250:35810 SIP/2.0 503 Service Unavailable FROM: "AMBOZOO"<sip:25006@10.10.60.250>;tag=40478~bb16990c-bb8d-474d-e339-4cb6bd7d93e7-23478979 TO: <sip:820993@10.10.30.23>;epid=4A4C146B07;tag=707bec76e1 CSEQ: 101 INVITE CALL-ID: ff535980-d191edc8-41b-fa3c0a0a@10.10.60.250 VIA: SIP/2.0/TCP 10.10.60.250:5060;branch=z9hG4bK41e3a437828 CONTENT-LENGTH: 0 SERVER: RTCC/6.0.0.0 MediationServer ------------EndOfOutgoing SipMessage TL_INFO(TF_PROTOCOL) [SFB\PR-VM-SFB-01]1594.3D3C::07/01/2019-11:43:14.063.0000200C (S4,SipMessage.DataLoggingHelper:sipmessage.cs(801)) [546807437] <<<<<<<<<<<<Incoming SipMessage c=[<SipTcpConnection_5291CE>], 10.10.30.23:5068<-10.10.60.250:35810 ACK sip:820993@10.10.30.23:5068 SIP/2.0 FROM: "AMBOZOO" <sip:25006@10.10.60.250>;tag=40478~bb16990c-bb8d-474d-e339-4cb6bd7d93e7-23478979 TO: <sip:820993@10.10.30.23>;epid=4A4C146B07;tag=707bec76e1 CSEQ: 101 ACK CALL-ID: ff535980-d191edc8-41b-fa3c0a0a@10.10.60.250 MAX-FORWARDS: 70 VIA: SIP/2.0/TCP 10.10.60.250:5060;branch=z9hG4bK41e3a437828 ALLOW-EVENTS: presence CONTENT-LENGTH: 0 DATE: Mon, 01 Jul 2019 11:26:00 GMT USER-AGENT: Cisco-CUCM11.0 ------------EndOfIncoming SipMessage Any help will be appreciated. thank youSolved7.5KViews0likes1CommentSFB office web app link (cipher suite)

I have tried to unlink the cipher hardening in group policy and it was advertising more cipher (windows default cipher) and i was able to browse the office web app link. the sfb server is running sfb 2015 cu7 and windows 2012 R2. the following update was applied https://docs.microsoft.com/en-us/windows/desktop/secauthn/tls-cipher-suites-in-windows-8-1 although some update was saying not applicable for the machine when i tried to install again. I was able to see the cipher suite listed in the microsoft link (https://docs.microsoft.com/en-us/windows/desktop/secauthn/tls-cipher-suites-in-windows-8-1) using wireshark after removing the cipher hardening policy. does anyone knows why the cipher suite in the group policy does not take effect? or what might have conflicting it? I have to get the hardened cipher suite to work with the load balanced office web app link. Thanks! Edit: I have further tried to create a new policy as in following table "Match". The idea is to get hardened cipher suites and apply it only to Windows 2012 R2. The table "Wireshark" refers to cipher suites gather from the machine without any group policy/or cipher order with Wireshark "Hello".

Hi, hoping someone can help me with an issue we are facing. We have a client with Skype for Business Server 2015, as well as mailboxes in Office 365. We have recently moved some users from their Office 365 tenant into a different tenant with a different domain. The users now sign into outlook with user@domainb.com but still sign into Skype on Prem with user@domaina.com. When they try and create a Skype meeting in their Outlook after the migration they receive an error to make sure they are signed into Outlook and Skype with the same email, which of course they are not. I have looked at various articles dealing with SIP and SMTP mismatch and they advised to set DisableEmailComparisonCheck to true. I have tried doing this both in the registry and also by creating a separate client side policy with Email check disabled and scoping it to a test user but I am still unable to create meetings. I know the policy is taking affect as if I make other changes to it, ie disabling emoticons the test user picks up those settings. Does anyone have any experience with having different SIP and SMTP addresses with S4B server 2015 and Skype client 2013/2016? Thanks Nick1.4KViews0likes2CommentsSFBO, Client Policies, Conferencing Policies, External Access Policies.
Hey Guys, I am getting ready to take my 70-347 exam and despite the tremendous amounts of studying i have been doing... The one area where i am pretty confused is on creating various policies. Like for instance this documentation here says that if you want to create a new CS-Client Policy, you need to reach out to office 365 support? https://docs.microsoft.com/en-us/lyncserver/identities-scopes-and-tenants-in-skype-for-business-online Per-user policies must be created for you by Office 365 Support. After the policies are created, you can then assign them to users by using the appropriate Grant-Cs cmdlet (for example, https://docs.microsoft.com/powershell/module/skype/Grant-CsExternalAccessPolicy). Per-user policies are easy to identify because the policy Identity always begins with the tag prefix. For example: Is that true, do you need to have O365 support create Conferencing Policies, User Policies, External Access Policies? I realize you can use the Grant-* Command to set the policy for a user, or the Set-* command to modify existing policies but i cant find any clear documentation that explains whether or not you need to have office 365 support create the policies. If someone could shed some light on that and provide an explanation as to what changed and when. Thanks, Robert1.3KViews0likes2Commentsaudio levels during Skype meeting
Good morning! Are there any SfB Server administrative controls available to modify level or adjust AGC for inbound audio from phones or interop devices like Polycom RealConnect on premise? We occasionally get complaints from users that inbound audio from Polycom Group Series or call phone calls is low during Skype meetings. Skype > Skype audio and Polycom > Polycom audio is good, low volume seems to only affect interop calls and some cell phone calls. Thanks!810Views0likes0CommentsJoin Zoom meeting from Skype Room System v2
Hi there, Trying to join a Zoom meeting from Skype Room System V2. We can join the meeting using the SfB client or on a Polycom Trio signed in with a skype account. We do so by dialing: 4105555555@lync.zoom.us However, on SRS v2 the dial pad only supports numeric input. Is this something we can enable, or that might be available in future updates?Solved22KViews0likes12CommentsCheck out these Microsoft Teams and Skype for Business sessions at Microsoft Ignite!

Our organisation has recently moved to SfB Online for telephony - replacing traditional desk phones for internal and external calling. A bit of background to help set the scene.... We have an on-premise (Cisco) PSTN connectivity with (Sonus SBC) Cloud Connector Edition setup. We have been unable to get meaningful CDR reports for users from either Cisco or SfB Online: These users don't appear in the SfB Online PSTN usage report (presumably because we don't have an O365 calling plan) These users don't appear in Cisco CDR as Cisco is handing off the call to SfB Online We would like to be able to report on the following, down to the individual user level: Call volumes (calls made/received) abandoned call rate answered call rate internal calls made external calls made We have not implemented auto attendant or call queues, as this is not the way in which the organisation operates.

Hi all, May I ask how do you troubleshoot the SRS devices? I have an issue where device suddenly (in a new location) lost the connection to calendar (on premises). On the event logs there is SRS log category, but that does not enlight anything. I was hoping to find plase where it really says in which situation the connection fails. But also, can we somehow troubleshoot if the apps does not work? One simple is e.g. the network trace, has anybody success to take locally the network trace on SRS?9.7KViews0likes1Comment
