We've got the following set up: Local Phone <-SIP(no reinvite)-> Local * <-IAX-> Central * <-SIP(no reinvite)-> Remote Phone I've got calls working just fine between Local and Remote phones. All of the outgoing calls / voicemail / Music on Hold are done on the Central * server. I would like to configure it so that the Local Phone can use the Transfer facilities on the Central * server. No matter what I do it seems that the Local * server always intercepts the # key. Is there anyway to transfer 'control' of calls to the Central * server if a call is placed via the Local server? I've searched in vain for info on Authenticated Transfer (is that what is needed?). Thanks, Stephan Wik ANU Galway
