DTMF via H323 PSTN trunk with G711 codec

Hello,

There is a system working in our lab.
We configured a H323 trunk to be reached PSTN connection.
This IP trunk works with G711 codec. The call is established for both directions (incoming/outgoing) properly. But if I send a DTMF tone from Alcatel OXE, the OXE - PSTN direction becomes totally silent! Only DTMF codes could hear on PSTN side, there is no speech coming from OXE (the voice coming from PSTN is OK)! If we use G729 codec there is no problem regarding both direction.
If somebody has an idea to be solved the pb. please share with me!
