-----------------------------------------------------------

I'm experiencing this problem on a production system running 1.8.24.0 which was released over a year after this issue was opened.

Is it worth trying a newer version? How are others getting around this issue? I see there's no resolution to this issue or this related issue: ASTERISK-19711

In my case, it's from dynamic hints:
{noformat}
exten => _X.,hint,${IF($[${EXTEN:0:3} = 83]?SIP/${EXTEN}:Custom:83-${EXTEN})}
{noformat}
(If they are trying to subscribe to anything beginning with 83, then it's a SIP device, otherwise it's a custom device).

Doesn't appear to be related to special characters.
