Syd:
CallerID Name is a funny animal.
I'm not 100% sure that your provider's explanation makes a lot of sense to
me because most of the signals sent are digital but allow me to give this
little backgrounder on CallerID Name
First of all it is important to note that we are very lucky in Canada. The
way the CallerID name system works here is much different than it is in the
US. In Canada CallerID Name information is set with every call. In the US
it is stored in central databases. Unless you have access to those
databases (or your provider will update it for you) you are out of luck when
it comes to changing the CallerID Name.
Ok, back to Canada. Chances are that your provider is using ISDN-PRI trunks
to their provider. There are 2 ways that CallerID Name can be passed with
ISDN-PRI. The first method, commonly used by Nortel DMS switches (think
Bell, Allstream), is by passing the name as a parameter in the call-setup
message. The other way, commonly used by Lucent 5ESS switches (think
Telus), is by passing the name as a Facility IE usually in the progress
message.
So the problem is *likely* that your provider's equipment is either
configured for the wrong switchtype, doesn't have the CallerID name
configured correctly, and/or doesn't support sending CallerID name in the
same fashion as their provider.
Asterisk supports sending CallerID Name using both methods. The method can
be set via the facilityenable parameter in zapata.conf. But this is only if
your connections to your provider are PRI.
So the reality is that there is nothing that you are doing wrong with your
CallerID Name via SIP. The problem is just that your provider and their
provider are likely either configured wrong or incompatible with each other
when it comes to CallerID Name

Bill

Subject: [on-asterisk] Suck it up - No Caller ID - comments?
Hey all.
My caller id _name_ info is not coming across. According to my provider,
"we send callerID correctly however the ISP's have old equipment that
don't understand the new digital signal therefore they can't understand
the call display".
I've check my sip dialog and know that I'm sending name and number. I
never had this problem with my previous voip service provider.
Can anyone provide me with additional insight into "the new digital
signal" versus the old one?
Thanks.. Syd
