For my understanding. Translating ISUP into SIP signalling is usually
done in a gateway. Carrying ISUP within SIP defies the reason for the
existence of both protocols. Is like using SMTP to carry web pages or
vice versa. Or storing MP3 in the DNS.
Why should SIP-T still exist? Is it cheaper than having a gateway?
What is the practical use case for investing in such technology?
I am eager to learn

One question that I'm not sure of.. Are there any extensions in epru
SIP-T that specify remote interface to use, such as used in
H.248/Megaco? ie: dial 123 on TCIC 000010012

That is accurate.

From what I understand about SIP-T it's SIP + ISUP params in the

Group, feel free to correct me there. Depending on your specific
setup
and network architecture, it should work. However, you may not be
able
to do anything with the ISUP components of the messaging.

Hi Alex.
If a different protocol is not to say that you can connect
directly to
Asterisk and will work, just taking the resources of ISUP?
SIP-T is not talking with SIP protocol are different, after all
SIP-T
carries information that the SIP can not interpret.
The Problem is the following I get a SIP-T trunk and Asterisk to
deliver
precise, how best to do.

Not possible, Asterisk doesn't understand SIP-T.
What do you mean by that, anyway? Only a device that supports
ISUP
interworking will support SIP-T.
Secondly, as is often repeated here, SIP-T is a specification
for a
_PAYLOAD_ - an extension - of SIP. It is not a different
protocol.

Hi List.
I have a trunk SIP-T must deliver it to the Asterisk in SIP.
The Opens
is that?
How should be my opensip.cfg?
