SIP/2.0 488 MediationCall SetupCall error: Media when transfer call external call failed RRS feed

  • Question

  • I checked the refer is enable and the gateway is support Refer. Audiocodes M1K 6.8 and running on SBC mode.

    I found another site M1K 6.8 running GW mode with refer transfer external call OK.

    Any suggestion? still try disable refer first?

    Thanks.

  • Typically this is my go-to, yes, try disabling REFER to see if the issue goes away.  If it doesn't you may want to leverage AudioCodes support to find out what in your config doesn't like it.
