Eric,
The sip module is not loaded in the latest release. This is for security reasons since most don't use it. Comment out (put a semicolon) before the noload=chan_sip.conf in modules.conf
I know you didn't ask this questions but there is a simple fix for the phone portal not working which will be in the next release. You need to comment out or remove ilbc in the allstar-public and allstar-sys contexts in iax.conf
Remember that if you make changes in the rpt, extensions, or iax files they will be overwritten when you run node-setup.sh another time. See instructions at the beginning of those files.
The gps module is also commented out. Again since many don't use it. Do the same as for sip for for noload=app_gps.so in modules.conf
Restart asterisk after making those changes.
You should probably ask BBB questions in the arm-allstar email list not on app_rpt. That arm-allstar list is specific to the BBB.

I hope that helps. I am copying this to the arm-allstar list so others may benefit.

Very good. Thanks for the help! The Pentium 4 to BBB transfer has
gone very smoothly thanks to your image file and
documentation. Echolink.conf worked immediately after editing and restart.
The last couple minor issues:
1. My SIP phone (Zoiper software on a smart phone) which worked well on the
old P4 server, is still able to connect to the BBB nodes and PTT but
no audio or telemetry is passed either direction. Codec problem?
2. I copied the old gps.conf file to the new system but it
doesn't seem to be enabled? (It used to place an icon on the aprs.fi
map)

Eric,
Glad to hear you got it going.
plfilter when activated applies a highpass filter to help to eliminate
incoming PL tones. They are not so noticable on a handheld but would be very
objectionable on an iaxrpt connection with full range speakers.

Thanks Doug! De-emphasis was set backward on the 900 repeater.
DTMF works like magic now. Just for my own education, what does plfilter do?
Many Thx!

My thinking is your
problem is either levels or maybe you are running non deemphasized audio
with simpleusb causing unequal tome levels. If so you need to program the
Motorola for deemphasized audio out OR set the deemphasis=yes in
simpleusb.conf. You should also run plfilter=on which is the
default.
Skewed equalization can definitely cause poor or no DTMF
decoding. The radio relaxed should have nothing to do with
it.
The BBB DTMF decoding works fine if the levels and
equalization are correct out of the radio.
YHou also need to use
preemphasis going into the Motorola with simpleusb or your audio will sound
flat (lacking high-end) at the other rx end. There is no SW setting for
this.

I just successfully installed Doug's
(WA3DSP) Beagle Bone Black installation on a two node repeater system using
two URI's and a Belkin 4 port USB hub in an attempt to remove my power
hungry old P4 rack server from All Star service. Everything seems to be
running well on the BBB with only 14% CPU usage on stand by (2 nodes)
and little to no audio distortion while testing.
I am having a heck of a time getting either node to
reliably decode DTMF especially when using Motorola transceivers.
(On the old P4 server, the DTMF decoded remarkably well using any
radio...) I have been looking at the old P4 config files and comparing them
to the BBB config in an attempt to see what has changed... Doug has "radio
relax" turned off by default (normally on by default in the acid release).
Is this relevant? Thanks!
