Hi,

According to H248 protocol chapter 7.1.3:
When a bearer termination is added implicitly to a context as a
result of the creation of an N × 64K multiplexing termination, the streamDescriptor for the bearer
termination shall take on the same values as the streamDescriptor defined for the Multiplex
termination, except that the bearer termination bandwidth shall be 64 kbit/s.

It means the terminations in the Multiplex descriptor is implied, doesn't it?
If there is a call context which its topology is just as below,
                  +-----------------------------------+
                  | Context123  +-------+             |
                 +----+         |       |             |
   Circuit 1 -|--| TC1|---------+ Tmux  |             |
              |  +----+ (Str 1) |       |  Audio    +-----+
              |   |             |       +-----*-----+     |-----
              |  +----+         | H.22x | Stream 1  |     |
   Circuit 2 -|--| TC2|---------+ multi-|           | TR1 |
              |  +----+ (Str 1) | plex  |           |(RTP)|
              |   |             |       |  Video    |     |
              |  +----+         |       +-----*-----+     |-----
   Circuit 3 -|--| TC3|---------+       | Stream 2  |     |
              /  +----+ (Str 1) |       |           +-----+
             /    |             +-------+             |
            /     +-----------------\-----------------+
TC1, TC2, TC3 are contained in the MUX descriptor. Tmux is the multiplex termination, in normal case,
it can be the TC1. Then what is the response of the transaction request: "C=123{AuditValue=*}"?
Is it "C=123{AuditValue=TC1{...}, AuditValue=TC2{...}, AuditValue=TC3{...}, AuditValue=TR1{...}}",
or "C=123{AV=TC1{Mux=H.226{TC1, TC2, TC3}...}, AV=TR1{...}}"?

Regards,
Shi Hao
