Doug Lawty came up for the fix. This may still work even for 2013 might be worth taking a look.<br /><br />http://blogs.technet.com/b/dougl/archive/2009/07/30/ring-back-workaround-for-ocs.aspx<br />Chris Normanhttps://www.blogger.com/profile/07200178774058910421noreply@blogger.comtag:blogger.com,1999:blog-2158853543793456735.post-79338622229064215572014-10-09T19:09:37.259-07:002014-10-09T19:09:37.259-07:00Hey Chris,
You're blog is awesome and has been...Hey Chris,<br />You're blog is awesome and has been saving my behind on installs since 2009 (we use Cisco gateways whenever TLS isn’t a requirement).<br /><br />Recently we found a ringback issue that we’ve either never noticed before or maybe is something due to newer IOS versions/Lync 2013. Ringback works for all scenarios, except when a user is completely logged out and has simultaneous ring enabled. In that case it just goes silent until voicemail finally picks up.<br /><br />We spent a couple of weeks working with Cisco TAC, but they finally said they were unable to fix the issue via the gateway. We could get it to work using various adjustments to the 181/183 SDP settings…but in those cases it would break other more critical scenarios (like logged in, signed out/no call forward, or even all calling).<br /><br />Any chance you have any ideas?<br /><br />We used the following settings (based on the 2013 MSFT/Cisco integration document and your blog):<br /><br />sip<br /> min-se 600 session-expires 600<br /> asserted-id pai<br /> midcall-signaling passthru<br /> privacy-policy passthru<br /> privacy-policy send-always<br /> block 181<br />*******<br />dial-peer voice 410 voip<br /> description DIDs going to Lync<br /> huntstop<br /> destination-pattern <br /> rtp payload-type comfort-noise 13<br /> session protocol sipv2<br /> session target ipv4:<br /> session transport tcp<br /> incoming called-number <br /> voice-class sip localhost dns:<br /> no voice-class sip early-offer forced<br /> voice-class sip block 183 sdp present<br /> no voice-class sip block 181<br /> voice-class sip options-keepalive<br /> dtmf-relay rtp-nte<br /> codec g711ulaw<br /> no vad<br /><br />******<br />dial-peer voice 104 pots<br /> description NANP Outbound<br /> preference 2<br /> destination-pattern 1[2-9]..[2-9]......<br /> progress_ind alert enable 8<br /> port 0/0/0:23<br /> forward-digits all<br /><br />Thanks!!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2158853543793456735.post-21132998676083402972014-04-03T02:11:22.712-07:002014-04-03T02:11:22.712-07:00i always have intermittent one way audio issue in ...i always have intermittent one way audio issue in my lync infrastructure. its also connected to a cisco isr gateway router any tips or ideas?Anonymoushttps://www.blogger.com/profile/03325593781929522107noreply@blogger.comtag:blogger.com,1999:blog-2158853543793456735.post-71609593895935538142013-05-08T08:28:04.027-07:002013-05-08T08:28:04.027-07:00Thanks for the tip.

For me the voice-class sip block 183 sdp absent<br />fixed it. However it did not fix ringback for calls forwarded back to PSTN. I took your advice and used debug ccsip message and discovered i was getting a 181. So I added voice-class sip block 181 sdp absent, which corrected this.<br /><br />Thanks!!<br />Anonymousnoreply@blogger.com
