No joy placing ignore_display_updates=true in the dialplan, or using <param name="send-display-update" value="false"/> in sip_profiles/external.xml.  Either way, handsets still updates with "tech_prefix*number_dialed".  With the console on debug loglevel, I don't see anything about it processing (or not) the command, although I'm not sure I should.  Cold restart of FreeSWITCH does not fix it either.

If it matters, running version string is: FreeSWITCH Version 1.5.13b+git~20140517T062858Z~34807208c6~64bit (git 3480720 2014-05-17 06:28:58Z 64bit)


<action application="export" data="ignore_display_updates=true" />

I've tried searching for the solution to this problem, but I've come up empty.

I'm working with a gateway (FlowRoute) that requires a Tech Prefix be sent in the INVITE as part of the outgoing number.  I've implemented this in the dialplan as:

<action application="bridge" data="sofia/gateway/sip.flowroute.com/123456*$1"/>

While the call is successfully routed out, FreeSWITCH sends the same information back to the caller in the SIP transaction -- thus the caller's handset updates to read "123456*1231231234" instead of just "1231231234".  Not only is this something of a security concern (since the Tech Prefix is somewhat confidential), but it breaks many handset features such as redial.  The gateway requires the Tech Prefix in the INVITE header and will not accept it just in the "To" field.

Any ideas on how I can force FreeSWITCH to effectively hide the Tech Prefix from the caller?

Thanks!
