wellread01 Posted September 21, 2013 Report Share Posted September 21, 2013 I recently added a Grandstream ATA (firmware v18.104.22.168 [latest]) to my snom ONE PBX (5.1.1 (Win64)). Caller ID works fine with the Grandstream ATA (i.e. the attached phone displays the CID) if the Trunk Routing/Redirection Default Account is set to the ATA's assigned extension. However, if the ATA extension is part of a Hunt Group where the Behaviour: From-Header is set to Calling-Party (or any other setting), the ATA's attached phone simply displays "Incoming Call". I don't have any experience debugging these kinds of problems and any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
