The Mk-II Safety Net for Lync Gateway AD-Lookups

My August “Safety Net for Lync Gateway AD-Lookups” plugged a sometimes embarrassing hole in the AD-lookup process, but it still left a smaller one. Whilst it ensured a user was EnterpriseVoiceEnabled before the UX would send a call to them, it didn’t cater for those deployments where the user’s msRTCSIP-Line number was in the “;ext=” …

Updated 12th December 2011. (Scroll to the bottom) We’ve found here in Oz with the UX that occasionally a random failure code from the carrier is enough to block the entire gateway. The NET faithfully interprets the applicable standards, mapping the ISDN failure messages to their SIP equivalents, then sends the resulting message to Lync. …

Tenor “108 Routing”

The NET (nee Quintum) Tenor gateway family has recently seen a functionality injection with the introduction of what they’re calling “108 Routing”. Until now the Tenor has had some limitations in its routing capabilities. One such restriction was that the outbound (IP) destination was either H.323 or SIP – you could never run both in …
