| Summary | 0010981: investigate unclear SMS send failure on my.taler-ops.ch [4h] | ||||
| Description | Sending an SMS failed, but the provider 1 (telesign) seemed to have just returned 203. The other provider (clicksend) returned 400. Maybe the phone number was not in the right format? We observed recently that the scripts do not seem to do any normalization (stripping spaces etc.), but I would've assumed the SMS providers take care of that. | ||||

| I just learned from Martin Riedi that they used a landline number. When they switched to mobile, it worked. We need to make it more clear to use a mobile number in the SPA, *and* see if we can detect landline numbers by their structure and reject them early on. | |
| Mobile phone numbers in Switzerland start with +417, so we should allow the merchant backend to also impose a restriction on the phone number entered and not permit landline numbers to be provided in the first place. | |
| I've pushed a restriction for +417 for the exchange challenger SPA configuration on spec. | |
| we can also return a specific error code when the number failed and the SPA can translate that (with i18n) "this number doesn't work, try another one" | |
| I've fixed the 500, now returning 502. There is now a FIXME in the backend to make the details on 502 more precise. | |
| taler-docs.git, 18ce41f9..2a7639e4 specifies a new phone_regex option in /config to allow the SPA to restrict the phone number on before submission. | |
| c2bba221..f38d7fab works more on the specification. | |
| c518e5ee..535ecdb9 adds the phone_regex to /config in the merchant backend. | |
| 535ecdb9..9db8b714 adds backend validation of the number against the regex. Left to do: better logging and error reporting by the SMS helper(s). | |
| SMS helper scripts are now more verbose, in particular they log the failed phone number. | |
