IP Trunk group stop sending digits

[cavagnaro]

I have an IP Trunk configured to send 4 digits. I connect here some h323 terminals in order to use them as terminals. For about half hour it works fine, however then it suddenly stop sending those four digits. I had to reset the PBX (OXE) and it worked again. Then it failed again. Did anyone had this kind of issue already?

Any help will be apreciated.
