Re: [asterisk-users] CEL custom variable in outbound channel
Unfortunately I am stuck with 1.8 for the moment. The only workaround that comes to my mind is to use userfield in the master channel as a shared storage to also pack all the information (CSV or similar) that applies to the outbound channel(s) and then to correlate the CEL events in a post-processing step in order to pull out the info that applies to the outbound channel from a linked master channel event.

In Asterisk 11, you could use a pre-dial handler [1] to apply the userfield directly to the outbound channel on the initial Dial.

However, if you use Local channel agents, then you could use pre-dial to put the userfield information on the callee SIP channel when the Local channel performs a Dial to the actual SIP device.
