[Freeswitch-users] mod_callcenter setting caller name on a per call basis

[Mike]

Hi,

I'd like to use mod_callcenter to have the agents answer calls on
behalf of multiple clients.

The simplest way  - and the way that I'm doing it at the moment
(without mod_callcenter) is setting the caller_id_name in the dialplan
based on the dialled number. So it's a bit of a fudge, (as it should
be the called_id_name as it were),  but at least it displays on the
phone so that the agent can answer properly:

123 calling 555(ACME) displays:
From: ACME
123
Agent answers "Hello ACME, how can I help you"

456 calling 666(Bedrock) displays:
From: Bedrock
666
Agent answers "Hello Bedrock, how can I help you"

With mod_callcenter the wiki says:

<!-- If you would like to set the Caller ID name, for whatever reason
notice below. -->
<agent name="1001 at default" type="callback"
contact="[origination_caller_id_name='Queue Caller']user/1001 at default
<snip>

Which works fine with a fixed value, but trying to include a variable
set earlier in the dialplan like:
<agent name="1001 at default" type="callback"
contact="[origination_caller_id_name=${the_name_I_set}]user/1001 at default
<snip>

Throws an error:
2012-03-09 10:59:25.810882 [CRIT] switch_channel.c:1183 Invalid data
(${sip_from_display} contains a variable)
2012-03-09 10:59:25.810882 [CRIT] switch_channel.c:1183 Invalid data
(${sip_full_from} contains a variable)

I understand the security reasons for not allowing variables within
variables - as explained by Brian here
http://jira.freeswitch.org/browse/FS-3015

So - given all that - any suggestions on how to get this to work with
mod_callcenter?
