Surely there must be someone here who can help me with this problem.

I have spent weeks trying to get this damned service to work with no
luck. I have incoming calls working, but no outgoing. If get outgoing
working then incoming don’t work.

I have sent this problem to this list a couple of times with little or
no response, and I _really_ need some help to sort it out.

I have an asterisk 1.8 server running on FreeBSD 8.1, and another
FreeBSD 8.1 running as a firewall/gateway with PF.

I have a nodephone service with Internode (who have been absolutely
useless in helping me- they point blank refuse, or they say to open
everything right up to their server; which didn’t wok anyway btw).

I have been running endless tests on settings changes, tcpdumps on both
the firewall and asterisk, and hours poring over SIP rfc’s. I’ve only
managed to get a headache…

I have tried following best practices, worst practices, and still
nothing works.

My sip.conf looks like this:

[general]
context = default
bindport = 5060
bindaddr = 0.0.0.0
srvlookup = yes
allow = all
;allow = t140red
textsupport = yes
videosupport = yes
;allow = h263
maxcallbitrate = 384
register => sip-in? number>:@sip.internode.on.net/ externip =
localnet =
canreinvite = no
hasvoicemail = no
qualify = yes
nat = no
;rtptimeout = 120
rtpkeepalive = 5
;ignoresdpversion = yes
;directmediapermit =

[sip-in]
type = peer
host = sip.internode.on.net
context = internode-incoming
;externip =
;domain = internode.on.net,internode-incoming
;fromdomain = sip.internode.on.net
;fromuser = ;username = ;secret =
;auth = :@BroadWorks
;insecure = invite,port
;register => :@sip.internode.on.net
;nat = never
qualify = yes
canreinvite = no
;expire = 240

[sip-out]
type = peer
host = sip.internode.on.net
context = internode-outgoing
externip =
;username = fromuser = ;fromdomain = internode.on.net
;secret =
;qualify = yes
canreinvite = no
;auth = :@BroadWorks
;nat = never
;pedantic = yes
;insecure = invite,port
;ignoresdpversion = yes
;compactheaders = yes

As you can see I’ve tried lots of settings. It registers and peers with
the provider, but no outgoing. The provider can call me though.

In extensions.conf:

[internode-outgoing]
exten => _X.,1,Dial(SIP/${EXTEN}@sip-out)
exten => _X.,n,Answer(2)
exten => _X.,n,Playback(ss-noservice)

A switch evaluates variables at load time. An eswitch evaluates variables
locally at query time. An lswitch sends the variables intact through to
the switch backend.

Just recently I noticed that my Asterisk 1.8 server is giving the
following error at startup:

[Feb 9 17:48:56] WARNING[7968]: loader.c:387 load_dynamic_module: Error
loading module ‘��Է�Vi’: /usr/lib/asterisk/modules/��Է�Vi.so: cannot
open shared object file: No such file or directory

I have checked the modules directory and there are no files with
strange characters that I can see. The only extra modules I have are
the G729 codec and Lumenvox speech recognition. Both are loaded and
working. All expected functionality for Asterisk is working so I really
do not know what that module may be. Any ideas?

We have a customer who wants to forward an extension to their cell phone,
if and only if that extension is “unavailable”, or when the Dial() command
times out. However, should the Dial() command return “busy” it should go
to voicemail instead.

As far as I know, the dialplan doesn’t support this. Certainly not
natively or in any particularly easy or obvious way, and I can’t find
anything on voip-info.org to suggest that there is.

read the part at the bottom about ignoring sighup, if you’re using a
later version i think there is a option like agisighup that you can
use in the dialplan
