    Hello Caroline, 

    in addition to Fazal's answer, you can try our Rainbow Pilot tool which can give you some hints about connectivity issues. 

    In any case, I recommend that you contact your Rainbow reseller who can open a support ticket for you to move forward with the analysis.

    Regards,

    Hi Caroline, Hope you are doing great!

    The issue may potentially be caused by,

    Analyze SIP Signaling Delays:

    The delayed session establishment observed in Wireshark suggests a potential issue with SIP signaling. Common causes include:

    Network latency or packet loss.
    Overloaded or misconfigured SIP servers.
    Delays in DNS resolution if SIP requests rely on domain names.

    Inspect Rainbow WebRTC Gateway Performance:
    Verify if the WebRTC gateway is experiencing high CPU or memory usage, as this can lead to call handling delays.
    Ensure that the gateway's network connectivity is stable, with sufficient bandwidth.

    Check PBX and SIP Trunk Settings:
    Confirm that the PBX system is handling SIP requests efficiently.
    Ensure proper configuration of SIP trunks and no overloads or congestion during peak times.

    Firewall and QoS:
    Review firewall rules to ensure no delays are introduced by inspection or filtering.
    Audio Delay:

    The 15-second delay in audio upon answering could be due to media path establishment issues.

    Verify:

    STUN/TURN server accessibility for WebRTC.
    Proper NAT traversal settings for Rainbow clients and the WebRTC gateway.

    We recommend creating a Service Request (SR) on support.openrainbow.com, including the relevant logs and Wireshark captures, so we can analyze the issue further.

    Thanks & Regards,
    Fazal (Rainbow TAC support)
