This might have something to do with how the DTMF signals are passed
to the server. There are roughly two options: RFC2833 and 'inband'.
'inband' is what your ordinary telephone does - it just sends out the
frequencies through the voice channel. This has one drawback, which is
that those frequencies will be mangled by the compression that's used.
At least, this happens with the GSM codec. To solve this, RFC2833
could be used.

My version of linphonec (1.1.0) understands it just fine. Here is a
copy of my session:

$ linphonec
linphonec> call sip:address@hidden
Contacting  sip:address@hidden
linphonec> Connected.
linphonec> 1
linphonec> terminate
Communication ended.

the '1' got picked up, and transferred my call to the appropriate person.

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?
