Este documento descreve como o fluxo de chamadas portal do erro da Voz de cliente Cisco (CVP) trabalha.
A Cisco recomenda que você tenha conhecimento destes tópicos:
As informações neste documento são baseadas nestas versões de software:

Quando o serviço do Survivability não é permitido no CUBO ou no gateway de ingresso, o fluxo do erro CVP invoca um cvperror.tcl configurou no ingresso Gateway/CUBE ou VXML Gateway/CVVB. Este Tool Command Language (TCL) é provocado quando uma etiqueta 92929292 gerada pelo CVP é enviada ao ingresso Gateway/CUBE em um SORVO 302 movido temporariamente ou SORVO CONSULTA a mensagem.
O SORVO REFER é executado somente quando o CVP tem respondido já ao atendimento. O CVP faz uma reorientação quando o atendimento não foi respondido. Neste caso, envia uns 302 movidos temporariamente para o intiator do atendimento (ingresso Gateway/CUBE), que inclui um destino da reorientação no encabeçamento do contato.
Apesar do SORVO CONSULTE ou 302 movidos temporariamente mensagem, as tarefas principal do script cvperror.tcl são jogar uma mensagem de erro crítico armazenada no flash no ingresso Gateway/CUBE ou VXML Gateway/CVVB.
Fluxo de chamadas:
Rede telefônica pública do interruptor (PSTN)
Seletores 98041 do telefone 4008 ------ PSTN (CUCM)------SORVO-----CVP-----ICM----- (o ICM está para baixo)
O Survivability não é permitido no CUBO

At this moment the PSTN must sent a SIP Invite to the CVVB, since there is no SIP trunk between the PSTN and the CVVB,
the critical error message is not played and the call disconnects.
Nesta encenação desde que o sorvo do serviço suplementar movido-provisório é permitido à revelia, o gateway para a frente o atendimento ao autor, neste caso o PSTN (no laboratório, CUCM). Contudo, desde que o PSTN não tem um tronco do SORVO ao CVVB, a mensagem de erro crítico não joga e as disconexões do atendimento.
Em conclusão, a etiqueta de 929292 erros deve ser configurada e controlado pelo gateway. Não é relevante o que você configurou no destino de sessão no dial peer de entrada 929292 no Gateway/CUBE, desde que este dial-peer não é usado para nenhum trecho de chamada de saída.
