If you or your agents receive an error message in the dialer, you can use Warehouse Calls to track what went wrong using SIP codes.
Go to Warehouse in the menu on the left and choose Calls.
Go to Columns in the Warehouse menu on the right and add the column SIP code. Every call has its own SIP code which is used for controlling communication sessions.
Definition of SIP codes
1xx: Informational SIP responses
180: Ringing
The Destination User Agent has received the invite message and is alerting the user of the call.
183: Session Progress
This response is used to send extra information on a call that is still being set up.
2xx: Success responses
200: OK
Shows that the request was successful and that both the callee and caller have been connected.
4xx: Request failures
403: Forbidden
The server understood the request, but is refusing to fulfil it. This can happen for several reasons, one of them being that we are trying to call a premium number (high cost) which is blocked by default. Another reason for forbidden calls could be that the recipient is listed on a national DNC list.
404: Not found
The server has definitive information that the user does not exist (user not found). The number is invalid.
407: Consent needed
The source of the request did not have the permission of the recipient to make the request.
480: Temporarily unavailable
Callee currently unavailable.
486: Busy here
Callee is busy.
488: Not acceptable here
Some aspects of the session description request-URI are not acceptable. This can happen for several various reasons, one of them being that the caller id (outbound number) has been temporary blocked for some reason, mainly due to complaints.
5xx: Server errors
500: Server internal error
The server could not fulfil the request due to an unexpected condition.
501: Not implemented
The SIP request method is not implemented here.
502: Bad gateway
The server received an invalid response from a downstream server while trying to fulfil the request.
503: Server unavailable
The server is in maintenance or is temporarily overloaded and cannot process the request.
504: Server time-out
The server tried to access another server while trying to process the request and didn't get a timely response. This can happen for several various reasons, one of them being if the local network operator has temporary connectivity issues.
6xx: Global failures
600: Busy everywhere
All possible destinations are busy.
603: Decline
Destination can't or doesn't wish to participate in the call and there are no alternative destinations. This can happen for several various reasons, one of them being that the caller id (outbound number) has been blocked for some reason, mainly due to complaints.
604: Doesn't exist anywhere
The server has authoritative information that the requested user doesn't exist anywhere.
606: Not acceptable
The user's agent was contacted successfully, but some aspects of the session description were not acceptable.
607: Unwanted
The called party didn't want their call from the caller. Future attempts from the caller are likely to also get rejected.
