Calls and SMS that could not be written
Why a row appears
A finished call or an SMS is written into your Bitrix24. When that write does not succeed, the app keeps a row so the item is not only in a log you cannot see. Calls wait with the sync record. SMS that failed are listed under «SMS that could not be written».
A temporary problem (Bitrix24 or Telfa busy, or a rate limit) is retried with a growing pause. The import of older history stops after repeated temporary errors or a lasting error, and you continue it from «Import older history» after the cause is fixed.
What is stored for a failed SMS
A row that is only waiting to be written does not store the phone number or the message text. A row that failed keeps a sealed copy, including the text, until the write succeeds or for 30 days after the first failure. Then it is deleted.
What to check
- The Telfa key still passes «Check connection».
- The Bitrix24 user who installed the app can still open the CRM.
- The number is still connected in «Choose numbers».
Do not send the API token with a support request. The portal domain, the time, and the number are enough.
