Atxfer manager command (and channel feature) can't transfer to an extension including '#'
-----------------------------------------------------------------------------------------

                 Key: ASTERISK-20489
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20489
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Features
    Affects Versions: 10.1.3, 10.7.0
         Environment: Linux, 3.2.0-29-generic, Asterisk 10.7.0 and 10.1.3
            Reporter: Dade Brandon
            Severity: Minor


1) in app.c, ast_app_dbget: always breaks loop when receiving '#' (and doesn't append it to the dtmf string)
2) in features.c, builtin_atxfer: calls ast_app_dbget to retrieve transfer to extension
3) in manager.c, action_transfer queues dtmf frames to perform transfer

Because of this, if in the manager interface, I supply Exten: ##971, then it's read as an empty extension

Atxfer will not work on any extension that requires a #

I'm sure this won't receive top priority (And I rewrote my extensions already, that are auto generated by my crm...)

but I was looking for a long time in configs and docs, thinking that '#' being a terminatr was a config problem on my end


Could the lack of support for extensions containing a '#' be added to the documentation?


A solution could be to modify action_atxfer to set a flag indicating that dtmfs are being simulated, causing '#' to read in to the extension string, but I didn't opt to write a patch for that because I don't know if such a workaround for a relatively insignificant feature (atxfer) would meet Asterisk's code quality guidelines.  That solution doesn't work for a true dtmf initiated atxfer, though.  Can ast_app_dbget be rewritten to only stop at a '#' if it's sure that there's no possible matching extensions that could use this '#'?
