In http://jira.freeswitch.org/browse/FS-4994 I have seen, that the User-to-User header can be passed into a channel variable. But what obout the other direction? Is there a way to set this header on an outbound call? Or do I just have to prefix with "sip_h_"? -- With kind regards Peter Steinbach Telefaks Services GmbH mailto:lists (att) telefaks.de Internet: www.telefaks.de
