Defaults to 128000 bytes, which supports up to 800; calls of
ulaw at 20ms a frame.
With a large amount of traffic on IAX2 trunk, there is a risk of
bad voice quality when allowing the Linux system to handle
fragmentation of UDP packets. Depending on the side of each
payload, allowing the OS to handle fragmentation may not be
very efficient. This setting sets the maximum transmission unit
for AIX2 UDP trunking. The default is 1240 bytes which means
if a trunk’s payload is over 1240 bytes for every 20ms it will be
broken into multiple 1240 bytes messages. Zero disables this
functionality and let’s the OS handle fragmentation.
How frequently to send trunk msgs (in ms). This is 20ms by
default.
Should we send timestamps for the individual sub_frames
within trunk frames? There is a small bandwith use for these
(less than 1kbps/call), but they ensure that frame timestamps
get sent end-to-end properly. If both ends of all your trunks go
directly to TDM, _and_your trunkfreq equals the frame length
for your codecs, you can probably suppress these. The
receiver must also need to have it enabled.
Minimum amounts of time that IAX2 peers can request as a
registration interval (in seconds).
Maximum amounts of time that IAX2 peers can request as a
registration expiration interval(in seconds).
