BCM INTEROPERABILITY WITH COMMUNICATION SERVER 1000 AND MERIDIAN 1 WITH IP TRUNK

ERSION 5.2 JUNE 2007 PAGE 17 OF 20

Voice Activity

Detection (VAD)

• G.711 Silence suppression or VAD is disabled by default. Verify that it remains

disabled for interoperation with BCM.

• G.729A Silence suppression (VAD) is enabled by default. Ensure that the VAD

setting on IP Trunk matches the Silence suppression setting on BCM.

• G.723.1 Silence suppression or VAD is enabled by default. Ensure that the VAD

setting on IP Trunk matches the Silence suppression setting on BCM. IPT 3.00

G.723.1 VAD is always enabled regardless of VAD setting. IPT 3.01 G.723.1

VAD is enabled or disabled according to the VAD setting.

• VAD was previously referred to as Silence Suppression on BCM but was renamed

to align with Communication Server 4.5/4.0 terminology.

Fax Setting

• T.38 FAX and V.21 FAX tone detection is enabled by default. Verify that V.21

FAX tone detection remains enabled for T.38 FAX. Group 3 T.38 FAX protocol is

wrongly identified as T.30 in OTM 2.1 ITG ISDN IP Trunk Node Properties DSP

Profile General tab. Don’t be misled -- the FAX protocol is T.38.

Codec Mismatch Diagnostics:

Calls from BCM to Communication Server 4.5/4.0 with a codec mismatch are released

immediately by Communication Server 4.5/4.0 without ringing the terminating

telephone and without seizing an outgoing trunk for a tandem routed call. Succession

3.0 Overlay 96 D-Channel monitor shows the following diagnostic messages:

BCM to Succession

(For incoming calls from BCM that terminate to a station or an outgoing ISDN PRI)

DCH 10 IMSG SETUP REF 00008021 CH 84 0 0 0 TOD 17:18:46
