</div></div><div><div class="h5"><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Hi All, <u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">In the midst of trying to pilot a deployment of Microsoft Lync (mainly for non-voice collaboration, specifically IM) and integrate it with our Asterisk (11.6.0 if it matters) deployment and a “everything in one place” tool when people are out of the office. <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I have everything on the voice side playing nice from the Lync side (Lync->Lync, Lync->Asterisk, Lync->Asterisk->PSTN) but I can’t get calls from Asterisk->Lync passing. <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I think the root issue is Lync demands that the “line URI” be entered in a E.164 normalized format, and further specifies that if an extension is specified it should be entered as ;ext=. So, e.g. when I have myself set up in LYNC my Line URI is entered as “<a href="tel:+144044911100;ext=1407" target="_blank">tel:+144044911100;ext=1407</a>”. <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">If I try feeding that into an Asterisk DIAL() using any format I can think of (specific examples below) the call fails and the following is logged to console; it looks like Asterisk is dropping the “;ext=”… <u></u><u></u></p>
<p class="MsoNormal"> == Using SIP RTP CoS mark 5<u></u><u></u></p><p class="MsoNormal"> -- Executing [1407@yyyyyyy:1] Dial("xxxxxxxxxx", "SIP/lync/"<a href="tel:%2B14404491100" value="+14404491100" target="_blank">+14404491100</a>") in new stack<u></u><u></u></p>

<p class="MsoNormal"> -- Auto fallthrough, channel ' xxxxxxxxxx' status is 'CHANUNAVAIL'<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">On the other hand, if I change my line URI to a “random” and unused in Lync E.164 number without an extension and change the DIAL() to reflect that number… the call succeeds, so it seems like I’ve narrowed it down to just needing to figure out how to properly pass the extension to Lync. <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">The Googling I turned up didn’t seem too positive (and suggested using an Exchange Unified Messaging auto attendant and forcing the user to redial the extension once connected to the AA was the only alternative for non-DID users) but it seems like it should be relatively simple to bridge (what seems like a very small) gap. <u></u><u></u></p>
