When a Participant has disconnected message appears in the admin log, further information about the reason will be given in the Details field of the message.
This Disconnect reason is also shown when viewing historical information about a participant.
The table below lists reasons for disconnections that may be given, along with an explanation of each. Note that this is not an exhaustive list, because in some cases the disconnect reason is provided by the endpoint.
Any Abnormal events are not usually seen during the expected functioning of the system and may require further investigation or intervention.

|Call rejected||Normal||#pex150||The person being called did not answer or could not be reached.|
|Call disconnected||Normal||#pex151||An Infinity Connect client has been disconnected by themselves or another system other than Pexip Infinity.|
|Call failed - please contact your administrator||#pex158
||A call routing rule with an invalid regex replace string has been configured.|
|Failed to gather IP addresses.||Abnormal||#pex170||
The browser cannot find the local IP address. This may be due to ad blockers.
An Infinity Connect WebRTC client could not determine its IP address. This may because there are privacy extensions installed.
|Call Failed: Error: Could not get access to camera/microphone. Have you allowed access? Has any other application locked the camera?||Abnormal||#pex171||An Infinity Connect WebRTC participant has not allowed their camera or microphone to be shared, or has no camera or microphone available.|
|Timer expired awaiting token refresh||Abnormal||#pex190||An Infinity Connect WebRTC client was unable to refresh its token after 2 minutes. This is likely due to network issues.|
|Resource unavailable||Abnormal||#pex191||There was insufficient transcoding or proxying capacity on the Transcoding Conferencing Node or the Proxying Edge Node on which the call landed.|
|Participant exceeded PIN entry retries||Normal||#pex192||
The participant exceeded the allowed number of PIN entry attempts (3).
|AVMCU cannot connect to PIN-protected or locked conference||Normal||There are some limitations with merging and escalating Skype for Business / Lync meetings with PIN-protected Pexip Infinity conferences. (For more information, see Pexip Infinity and Skype for Business / Lync integration features.)|
|Backplane disconnected||Abnormal||A connection between two Conferencing Nodes was lost, and the participant was connected to one of the nodes.|
|Browser closed||Normal||An Infinity Connect participant closed their web app or desktop client.|
|Call transferred||Normal||The participant was transferred to another conference.|
|CCCP call disconnected||Normal||
The call from Pexip Infinity to the SfB/Lync server has been disconnected by a system other than Pexip Infinity.
The reasons include:
|Conference number entry attempts exceeded||Normal||
A participant using a Virtual Reception has exceed the allowed number of attempts (3) to enter a conference number.
Does not apply to Infinity Connect clients.
|Connection to the other side was lost in a non-clean fashion||Normal||An H.323 participant was disconnected by themselves or another system (other than Pexip Infinity).|
|Connection was closed cleanly||Normal||An H.323 participant was disconnected by themselves, another system, or Pexip Infinity.|
|Detected AVMCU call failure||Abnormal||Call to the Skype for Business / Lync server failed.|
|Dialog has failed||Abnormal||(SIP) A reverse connection could not be established. This is likely due to a TCP connection issue.|
|insufficient capacity||Abnormal||There was insufficient transcoding capacity on the Conferencing Nodes within the location the call landed on, and any configured overflow locations.|
|Local disconnect (No response to Round Trip Delay Request)||Normal||Pexip Infinity disconnected the participant because their endpoint did not respond to the request sent by Pexip Infinity.|
|No conference number entered||Normal||
The participant exceeded the allowed time at the Virtual Reception (120 seconds).
Does not apply to Infinity Connect clients.
|Participant did not connect in time||Normal||The outgoing call was not answered.|
|Participant failed to start audio channel||An ACK was not received from the far side. This may be because the far side never received, or failed to process, the 200 OK from Pexip Infinity, and therefore never set up media.|
|PIN entry timed out||Normal||
The participant exceeded the allowed time at the PIN entry prompt. (For more information, see Limiting the time a participant can spend at the PIN entry screen).
Does not apply to Infinity Connect clients.
|Presentation stopped||Normal||A Skype for Business / Lync participant stopped presenting.|
|RFC3263 lookup failure||Abnormal||The call could not be connected because DNS lookup failed.|
|Re-INVITE timer has expired||Abnormal||Failed to establish a connection to the far end in order to send a SIP INVITE message.|
|Remote disconnect||Normal||A SIP/H.323 participant was disconnected by themselves or another system (other than Pexip Infinity).|
|Session renegotiation failed||Abnormal||A reverse connection could not be established. This is likely due to a TLS (certificate) issue.|
|Timeout expired waiting for ACK||Abnormal||SIP: no ACK message was received within the default timeout period. This often occurs due to issues with DNS (such as unresolvable DNS records, or resolving to the wrong host) as referenced in the Record-Route or Contact SIP signaling headers.|
|Transaction failed INVITE <random string of characters>||Abnormal||SIP: INVITE message was not responded to within the default timeout period.|
|Transaction failed UPDATE <random string of characters>||Abnormal||SIP: UPDATE message was not responded to within the default SIP timeout period (32 seconds).|
