[Freeswitch-users] weird extra characters

[Joli Martinez]

Hello,

I am doing a pcap on the inbound and outbound leg.  The pcaps shows that
the characters are not being added until it sends the invite out it's
Gateway.  Before then the pcap does not show any anomalies.  Somehow on the
invite to the carrier the characters are being added not before.  I again
have made sure this is the case.  I wrote a Lua script that would strip out
any characters before, after and in between the called number.  And this
script is run right before sending the call out.  I know how to control the
call prior to it hitting the GW, what I don't know how to do is modify the
invite this far along in the call.
