486 Busy Here
If a call receives a “486 Busy Here” response, please check the status of the callee’s SIP UA.
- The callee’s handset may be off, busy, or already been hung-up.
If either Brekeke SIP Server or Brekeke PBX is responding “486” before an “INVITE“ is routed to the callee:
- For Brekeke SIP Server – Check the Dial Plan rule because it may have been set to send “486” such as “$response=486” or “$action=486”.
– Expand the RTP port-range in the [Configuration]->[RTP] page. The port range is between the [Minimum Port] and [Maximum Port].
- For Brekeke PBX – Verify if the number of calls have reached its maximum at the [Max concurrent sessions] field.
