Hi!

Using Asterisk as H324M Gateway requires correct Q.931 signaling.
Currently Asterisk does not care about User Information Layer 1 signaling
in Bearer Capability IE.

@Corydon76: If I understand it right, the datastore will be copied from
incoming to outgoing channel (inherited) by Dial() once the outgoing
channel has answered the call. Right?

In my case this is too late as the outgoing channel needs the ISDN
information during call setup. Any suggestions how to solve this?

Patching app_dial to inherit before the call is answered? Extending the
ast_channel structure? Maybe extending datastores to have differ between
datastores which will be inherited immediately and datastatore which will
be inherited after answering of the call.
