Relatively new to Asterisk and SIP and am trying to run a proof of
concept using Asterisk to make an outbound call through an Audiocodes
gateway via SIP using Asterisk version 1.6.1.12. The specific
requirements of the gateway in the configuration I am trying to use
specify that the Name part of the From header be blank with the outbound
number that needs to be dialed in the number field of the From header.
So I want it to look like this:
From: <sip:1234567890@192.168.3.110>;tag=xxx
However, even if I set the name to blank, using Set(CALLERID(name)= ),
Asterisk always seems to put the CallerID number in the name field as
well and here is what I get:
From: "1234567890" <sip:1234567890@192.168.3.110>;tag=xxx
I cannot figure out how to get the name field to be blank. Here is the
extensions.conf context that I think should work:
exten => xxx,1,Noop(Channel ID is ${CHANNEL})
exten => xxx,n,Noop(From is ${SIP_HEADER(From)})
exten => xxx,n,Set(CALLERID(num)=1234567890)
exten => xxx,n,Set(CALLERID(name)=)
exten => xxx,n,Noop(CallerID is ${CALLERID(all)})
exten => xxx,n(dialout),Dial(SIP/POTS1,60,o)
exten => xxx,n,Hangup
And my general and section from sip.conf
[general]
allowoverlap=no
udpbindaddr=0.0.0.0
tcpenable=no
tcpbindaddr=0.0.0.0
srvlookup=yes
disallow=all
allow=ulaw
allow=alaw
limitonpeers=yes
notifyringing=yes
maxexpirery=180
defaultexpirey=180
[POTS1]

context=pots_in
host=dynamic
dtmfmode=info
disallow=all
allow=ulaw
allow=alaw
canreinvite=no
qualify=yes
call-limit=4
rtptimeout=30
And here is the verbose CLI output from the above configuration.

As you can see the Noop on the Caller ID shows that the name is blank,
but Asterisk seems to default somehow to putting the number in the name
field if it is blank when the Invite is created. I've also tried various
combinations of setting CallerID(name) and (num) as well as some changes
to settings in sip.conf for this channel that should effect caller id
and cannot get it to clear. Is there a way to configure Asterisk not to
do this?
Thanks in advance for any insight you can provide.
