[cisco-voip] CER call out

[Jonathan Charles]

Symptom:

CER Onsite alert receives dead air
Sorry, hit send before I finished pasting...


CSCsg03127

Conditions:

CER 1.2(3) or 1.3(1a) with Onsite Alertees through external gateways
(cell phones etc)

Further Problem Description:

CER Onsite Alert mechanism has no voice detection and plays audio
immediately after a connect state. In Skinny devices this is an
issue with voicemail and was worked around by adding the RETRY
COUNTER to the PlayMessages.properties file. This workaround also
works for gateway users.

This issue is different and unique due to the PSTN factor. PSTN
connection adds unknown delay to the equation. The default retry
counter is 1 which all but completes speaking before the external
phone (cell phone) is connected. The user hears dead silence, does
not get the message, feels that CER is broke. If the user thinks
enough to hit asterisk (*) then the call repeats.

This is a specific problem to PSTN because of the fact that we cut
through audio at the CALL PROCEEDing stage with gateway calls - both
H323 and MGCP. When audio is cut through (be it via
StartMediaTransmission or whatever the trigger) CER starts speaking.

Workaround:

Set the rC-RETRY counter in the PlayMessage.properties file to value
greater than 1
C:\Program Files\Cisco Systems\CiscoER\etc
