| void IAX2FullFrame::MarkVnakSendNow | ( | ) |
A Vnak frame has been received. This Vnak frame is demanding that we resend this particular frame. Given it is to be resent by vnak, we reset the countdown variables. E.G. it gets the full amount of retries again.

Dry the current value of the subClass variable
| virtual PBoolean IAX2FullFrame::WriteHeader | ( | ) | [virtual] |
Write the header for this class to the internal data array. 12 bytes of data are writen. The application developer must write the remaining bytes, before transmiting this frame.
Reimplemented from IAX2Frame.
| void IAX2FullFrame::ModifyFrameHeaderSequenceNumbers | ( | PINDEX | inNo, | |
| PINDEX | outNo | |||
| ) |
Alter the two bytes for in and out sequence values. (in the header)
| void IAX2FullFrame::ModifyFrameTimeStamp | ( | PINDEX | newTimeStamp | ) |
Alter the four bytes for this frames timestamp. It is required, when transmitting full frames, that there is a 3ms interval to last full frame in the timestamps. This is required by limitations in the handline of time in asterisk.
