[asterisk-users] Surrogate channels

[Patrick Wakano]

Hello Asterisk list!

I've been facing some scenarios in my dialplan where I see the "h"
extension being executed for Surrogate channels.
For me, it is kind of a mystery what these Surrogate channels are... I
couldn't find good information about them... the source code is where I
could find the most detailed info:

/*! \brief Channel technology used to extract a channel from a running
application. The * channel created with this technology will be
immediately hung up - most external
 * applications won't ever want to see this.
 */

It mentions "*won't ever want to see this*", so I am unsure if they are
only internal to Asterisk core and I should not be seeing these channels
executing my dialplan, or if indeed I will see them in my dialplan, and
then I have to handle them somehow (even if I don't want them)....

Anyway, does anyone know a good explanation about these surrogate channels,
and what is expected of them when it comes to dialplan execution?

Cheers!
Patrick
