Mediant 800 MSBR SBA - SRTP errors RRS feed

  • Question

  • I have 2 Mediant 800 SBAs that I am trying to configure for branch sites.

    Ideally Ineed these to do SIP over TLS.
    I have successfully configured 1 to use TCP as the SIP transport. The other I have been trying to configure using TLS, without success.

    I have followed the Audiocodes setup guide here however when thje call hits the PSTN gateway I see the following errors in syslog:

    12:54:27.049 : : WARNING : [S=518] (      lgr_flow)(173       ) !! [ERROR] TlsTransportObject#134- CSocket::HandleSocketEvent socket error received, error: Broken pipe(32)

    I'm not sure what else I can provide that will useful. I am happy to provide any additional logs/traces that would be helpful.

  • Open Lync Server 2010, Topology Builder, click Branch sites under the center site, choose PSTN gateways, check the Sip Transport Protocol of the gateway is TLS.

    Make sure the PSTN gateway is running SIP firmware version SIP_F6.40A.019.008 or later.
