This chapter provides reference material applicable to the H.323 implementation.
Interoperability Data for Cisco IOS, Cisco CallManager, and MGCP
Table 6-1 through Table 6-7 provide information on the interoperability of the Cisco BTS 10200 Softswitch with H.323 IOS-based gateways, Cisco CallManager, and MGCP-based gateways.
The call configurations use the designations A, B, and C:
A = Input (incoming signaling from a remote endpoint)
B = MGCP-based subscriber line controlled by the Cisco BTS 10200 Softswitch, with the
specific feature subscribed and activated
C = Output (outgoing signaling to a remote endpoint)
Table 6-1 lists interoperability support for the Call Forwarding Unconditional (CFU) feature. In this case, the configured elements interoperate in the following manner:
A->B(CFU)->C — A calls B (B has CFU activated). The call is forwarded to C.
A<->C — A is connected to C.

Table 6-2 lists interoperability support for the call forwarding busy (CFB) feature. In this case, the configured elements interoperate in the following manner:
A->B(CFB)->C — A calls B (B has CFB activated). The call is forwarded to C.
A<->C — A is connected to C.

Table 6-3 lists interoperability support for the call forwarding no answer (CFNA) feature. In this case, the configured elements interoperate in the following manner:
A->B(CFNA)->C — A calls B (B has CFNA activated). The call is forwarded to C
A<->C — A is connected to C.

Table 6-4 lists interoperability support for the three-way call (TWC) feature. In this case, the configured elements interoperate in the following manner:
A->B — A is connected to B.
B->C — B calls C to establish TWC.
A, B, C TWC — A, B, and C are connected on TWC.

Table 6-5 lists interoperability support for the call waiting (CW) and call waiting deluxe (CWD) features. In this case, the configured elements interoperate in the following manner:
Note 
The interoperability for this case applies with or without codec up-speed.
A<->B — A connected to B.
C->B — C calls B.
A is on hold C<->B — B puts A on hold, and C is connected to B.

Table 6-6 lists interoperability support for the consultative call transfer (consultative CT) feature without codec speedup.
Note Consultative CT means that the transferring party (caller B) is connected to the transferred-to party (caller C) before completion of the connection of the transferred party (caller A) to caller C. Codec speedup refers to the transition to a codec type with a higher compression rate (such as PCMU or MCMA) during the call.
A<->B — A is connected to B.
A is on hold B->C — B puts A on hold, and calls C.
B<->C — B is connected to C.
B is on hook A<->C — B goes on hook, and A is connected to C.
