I didn't even realize you could use '_' in an extension name...   Your dialplan pattern doesn't appear to account for the '_' character. Let us know how fixing that affects it.

Does it behave the same if you make an explicit extension rather than a pattern match for a hint with an underscore in the name (even if you still pull it from the database)?

Can you provide a VERBOSE and DEBUG log set to at least 5 captured during the time the hint is being pulled?

Can you also provide the READ_BLF_PHONE_LIST() function code so we can better understand what is going on inside there?

> We use dynamic hints with a func_odbc call to load the hints from a database.  However, when the extension contains an underscore the func_odbc call is not evaluated.
> Our hint context:
> {code}
> [blf]
> exten => _[+A-Za-z0-9*#].,hint,${READ_BLF_PHONE_LIST(${EXTEN})}
> {code}
> When we look up the hint for extension johnDoe we get something like:
> Hint: SIP/phoneA&SIP/phoneB
> But when we look up the hint for extension john_doe we get:
> Hint: ${READ_BLF_PHONE_LIST(${EXTEN})}
> As you can see the variables are not even being evaluated.  If there is any more information you need to debug this please let me know.
