Call gets disconnected right after called party answers the call
Try to call SIP endpoints at different locations—and through different SIP trunks, if

If some test calls work, compare the working scenario(s) with the non-working scenario,
including the model and software version of the SIP call control device and of the SIP
endpoints. Compare network locations and configuration. Possible causes could be device

If any of circumstances above is still encountered but the points above do not help you
overcome the issue, place a single testing call and collect the following information:
Software version of Acano solution

Model and version of SIP call control device and SIP endpoints
State the problem, and attach SIP trace (see Appendix A)
