[asterisk-users] Text messaging

[Alex Balashov]

Hakan,

I did not ask about the purpose of Sendtext() - I know the purpose, 
and on the level on which you have explained it, it is self-evident.

I asked about how it was implemented underneath.  Even in the context 
of SIP channels solely, there are numerous ways to send what one might 
term a "message."
