Planet Technology IPX-2000 - Manual (Page 27)

2nd-dialing might fail. To avoid such problem, it is
recommended to set the same DTMF mode for all IP
extensions and SIP trunks in the IPBX, as well as for
all IP phones registered to the IPBX. If it is not
feasible to set the same DTMF mode for some IP
extensions or SIP trunks, and inline transfer or
2nd-dialing is necessary for those IP extensions or
SIP trunks, the Fast Bridging feature can be disabled
on a per IP extension and per SIP trunk basis. Note
that Fast Bridging is enabled by default.
