[asterisk-bugs] [JIRA] (ASTERISK-21897) D option in Dial doesn't recognize "w" as a pause

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=207487#comment-207487 ] 

Rusty Newton commented on ASTERISK-21897:
-----------------------------------------

This looks like a config issue. @Sean, you need to figure out exactly when you should be sending DTMF based on both whats happening with your SIP dialog (the reinvite that Michael mentioned) and any needs the far-end has. Often legacy equipment has some delay before accepting DTMF digits. It can be quite tricky, especially if you don't have any debug on the far end to see exactly what they are seeing.

Unfortunately this is not a bug report, so I'm going to close this out.

Fortunately, you have somewhere to start troubleshooting.

If you find something more like a bug, please feel free to contact a bug marshal on #asterisk-bugs.

> The D option in the Dial command does not recognize 'w' as a pause:
> Dial("DAHDI/1-1", "SIP/<>,,D(wwwwwww249#)") in new stack
>   == Using SIP RTP TOS bits 184
>   == Using SIP RTP CoS mark 5
>     -- Called SIP/<>
>     -- SIP/<>-00000063 answered DAHDI/1-1
>     -- Sending DTMF 'wwwwwww249#' to the called party.
> Interestingly, if you put other characters in the DTMF string, you get an error:
> -- Sending DTMF 'pwwwwwww249#' to the called party.
