Re: Text encoding for a proprietary TerminationState Descriptor package

Hello Christian,

We were aware of the Nokia and 3GPP packages but we decided to introduce
a new package for tracing activation/deactivation and some other MGC-MG

Do you really need another package for tracing? There's already the
following packages:
0x0097  calltrace
0x8007 threegtrace
(http://www.iana.org/assignments/megaco-h248)
