The visibilityprovided by Skype for Business helps businesses reduceoperating costs and time wasted by chasing colleaguesthat might otherwise be engaged.Our earlier Lync 2010 accreditation saw us becomeone of the UK’s first SIP providers to gain suchcertification and this latest accreditation adds to theexpanding list of platforms already qualified for usewith Gamma SIP Trunks.Whilst it’s widely acknowledged that SIP is going toreplace all other terrestrial voice protocols, the realityis that in a unified communications environment(such as with Skype for Business), this transition fromlegacy to VoIP is likely to happen more rapidly thanin any other.
