Not exactly.  The Echolink messaging is embedded in the Echolink data 
stream combined with the audio, and is essentially another proprietary 
black box that only works Echolink-on-PC to Echolink-on-PC.

About 3/4 of Echolink "QSOs" involve only computer-to-computer 
connections with no radio involved. The text message is primarily 
provided so that when several Internet-only stations are in a 
"conference" (i.e. roundtable; i.e. IP multicast), the stations that are 
not presently sending audio can send text msgs to each other while one 
station talks.  

1)    An amazing number of Echolink users are totally clueless about RF 
connections (they assume it is only Internet-to-Internet) and don't 
realize that a station away from their shack can't see the text messages. 

2)     An amazing number of Echolink newbies are totally clueless about 
the most basic audio operations in Windows and don't know how to enable 
or adjust their outgoing audio.   *AT LEAST* 4 or 5 times a week I get 
random connects to my node (Echolink provides a 
randomly-selected-connect function that sort of emulates calling CQ on 
RF) and then NO AUDIO because the user hasn't yet figured out how to 
access the Windows record mixer to enable outgoing audio (or has so much 
other garbage loaded into Windows in the background that Echolink can't 
gain access to the computer sound system).   They then resort to text 
messages not realizing that NO CAN SEE THEM on RF.  

This is such a frequent ongoing nuisance that my Echolink connect 
message text now says "This is an RF link. Text messages ignored since I 
can't see them".

If you can get onto Echolink at all, then firewalls are not the problem.
