Thanks - so, which one should I pass as the parameter to ChannelRedirect() when I want to put the call on hold (and then Bridge() when I want to join it back to the other caller again)?

Ah, splendid - thanks for the clarification. So, coming back to my original difficulty, if I want to put this "thing" on hold, should I do ChannelRedirect() on the ;1 or the ;2 part? Maybe even both?? I *believe* I have tried each (today my dialplan is processing ;2) and in both cases, as soon as the channel is put on hold, the hangup handler is called and the call ends. I am perfectly successful in using ChannelRedirect() for putting calls on hold when they are a SIP/ channel and not a Local/ one.

Re: [asterisk-users] Channel names with semicolons
From https://wiki.asterisk.org/wiki/display/AST/Channels "The primary exception is with Local Channels. In the case of local channels, you'll typically have two local channel legs, one that is treated as outbound and the other as inbound. In this case both are really inside Asterisk, but one is executing dialplan and the other is not. The leg executing dialplan is the one treated as inbound." In your case, context-0ce9;1 is the inbound channel because you did Dial(Local/number@context) and context-0ce9;2 is the outbound channel because it did the Dial to another destination. Simply, the numbers represent each leg of a local channel.
