OK I just tried to merge Cloud telephony into Web based VoIP and it did not work The reason is that the intros in both of those articles did not correctly define the concepts Cloud telephony is a subset of Cloud communications it means third party off site VoIP services in general This includes both web based and non web based VoIP it could just integrate with conventional telephones as a PBX replacement Web based VoIP simply uses a web page running a multimedia applet or whatever instead of dedicated non web VoIP software I propose merging Cloud telephony into Cloud communications instead they are both very short and weak and there is substantial overlap I tagged both of those articles There is no section in Voice over IP into which to merge Web based VoIP since it defines a class of client software though I did add an awkward link from the Protocols section Clients are described at Comparison of VoIP software Web based software is included there but not necessarily marked as such That s another potential merge target but I don t have any problem leaving web based VoIP as its own article for a while and letting it grow It may be handy to just be able to link there from several other articles I removed the merge tag from Web based VoIP for now but feel free to rekindle the debate if you see fit
