This new codec will get handled like RFC4040 in yrtpchan, ysipchan
and will just be handled as alaw audio in zapcard/DAHDI.
The zapcard code will set the udi bearer cap to any calls with the
clearmode format (which would get sent via SIP/SDP).
The user may suggest a given channel in the SETUP, but it's not legal
for the network to return a non-mandatory ChannelID.
See Q.931 Section 5.1.2 (B-channel selection - Originating):
The selected B-channel is indicated in the Channel identification information
element coded as "channel is indicated, no acceptable alternative" in the first
message returned by the network in response to the SETUP message (i.e. a SETUP
ACKNOWLEDGE or CALL PROCEEDING message)
In an earlier commit I had only fixed SETUP ACK, but missed that this is
a more general problem that needs addressing in whatever is the first
message containing a channelID yate sends in response to the SETUP.
The user may suggest a given channel in the SETUP, but it's not legal
for the network to return a non-mandatory ChannelID.
See Q.931 Section 5.1.2 (B-channel selection - Originating):
The selected B-channel is indicated in the Channel identification information
element coded as "channel is indicated, no acceptable alternative" in the first
message returned by the network in response to the SETUP message (i.e. a SETUP
ACKNOWLEDGE or CALL PROCEEDING message)
If yate is operating in the 'network' role of a PRI interface,
it must send a valid ChannelID InformationElement in the SETUP ACK.
However, current yate code is encoding the channel selection field
of said information element wrong, as it unconditionally looks up
the s_dict_channelIDSelect_BRI (instead of _PRI).
This fixes a regression introduced in 2009 in the following commit:
