Well, in that case, why not simply add this clamping feature into the
sip.conf general configuration, allowing the admin to set the maximum
duration for a DTMF over SIP connections. If SNOM messed up and are not
willing to fix, I think a general variable to address the issue should be
put into the code.

meric, can you please upload your patch into the ticket, so that we can
take a look at it. I'm still new to the channels code, but I'd like to take
a wiff at it, and try to make this into a configuration option or
something.
