[asterisk-users] Respond to an out of call SIP MESSAGE

Sorry for the delay here. For some reason the mail from Joshua Colp failed to
deliver to my mailbox.

So, anyway, I've set up a local scenario on my computer a PJSIP client and
Asterisk 11.17.1 (On a fedora linux workstation) with the settings listed below.
In this scenario I've used UDP, but I want a configuration that can be used
with any transport protocol.

I can see that the context runs correctly, but there is no message delivered to
the client. Am I approaching this the wrong way?

sip.conf:
[general]
context=public                  ; Default context for incoming calls. Defaults
to 'default'
allowoverlap=no                 ; Disable overlap dialing support. (Default is
yes)
realm=my_realm                  ; Realm for digest authentication
udpbindaddr=0.0.0.0             ; IP address to bind UDP listen socket to
(0.0.0.0 binds to all)
tcpenable=no                    ; Enable server for incoming TCP connections
(default is no)
tcpbindaddr=0.0.0.0             ; IP address for TCP server to bind to (0.0.0.0
binds to all interfaces)
transport=udp                   ; Set the default transports.  The order
determines the primary default transport.
srvlookup=yes                   ; Enable DNS SRV lookups on outbound calls

requests outside of a

Yes, that is how the problem was solved before when the transport protocol for
messages was UDP, but TLS (TCP) this doesn't work. Partly because
MessageSend doesn't support SIPS and partly because it focuses on sending a
new message instead of reusing an existing stream. Using wireshark I can see
that the TLS stream is still alive as there is no tear down communication.

The "same,n," is a good shortcut to make the text more readable,
I'll add that but I don't think that is the cause as I can follow the
source code and see that the SendText command is executed but fails silently.

Thanks for the feedback,
Emil

If you want to send an out of call SIP MESSAGE request, you'll need to
use the MessageSend application:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Application_MessageSend

SendText is used for sending text messages within a call. Since a SIP
channel is not servicing the out of call text message, you cannot use
it to send a SIP MESSAGE request back to whatever sent the original
SIP MESSAGE request.

As Matt stated the SendText application is for sending messages 
in-dialog within a call. It can't be used out of call. You have to use 
the MessageSend application.

[asterisk-users] Respond to an out of call SIP MESSAGE

(Still no not receiving the mail, revisited the settings.)

OK, so SendText doesn't work with this scenario. But can MessageSend handle
this, and respond even when the transport protocol is TLS? Or do I need to
modify Asterisk to add this support?

BR,
Emil

Sorry for the delay here. For some reason the mail from Joshua Colp failed to

Yes, that is how the problem was solved before when the transport protocol for
messages was UDP, but TLS (TCP) this doesn't work. Partly because
MessageSend doesn't support SIPS and partly because it focuses on sending a
new message instead of reusing an existing stream. Using wireshark I can see
that the TLS stream is still alive as there is no tear down communication.

The "same,n," is a good shortcut to make the text more readable,
I'll add that but I don't think that is the cause as I can follow the
source code and see that the SendText command is executed but fails silently.

Thanks for the feedback,
Emil

If you want to send an out of call SIP MESSAGE request, you'll need to
use the MessageSend application:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Application_MessageSend

SendText is used for sending text messages within a call. Since a SIP
channel is not servicing the out of call text message, you cannot use
it to send a SIP MESSAGE request back to whatever sent the original
SIP MESSAGE request.

MessageSend has no concept of TLS, it gets passed to chan_sip which then 
sends it. It's therefore up to chan_sip to do it. It should work. 
Haven't done it though.
