Hm. To use RTPEngine I need Kamailio, correct? Or can I use RTPEngine
just with Asterisk?
If I need Kamailio: Kamailio in the default configuration is behaving
differently than Asterisk in terms of the contents of the SIP header
fields that it sends by default to the carrier IP (please see my
So, forgive the silly question, but why do you need to do anything except to
engage RTPEngine? Why rewrite any other SIP headers?

Hmm, try to use: subst_hf() then:
3.15. subst_hf(hf, subexp, flags)
Perl-like substitutions in the body of a header field.
Meaning of the parameters is as follows:
* hf - header field name.
* subexp - substitution expression in the same format as of the 'subst'
function parameter.
textops.so was already loaded. Now added textopsx.so too but the error
remains the same.
Is $cU a pseudo-variable that should be available within Kamailio by
default? I can't find it here:
https://www.kamailio.org/wiki/cookbooks/5.5.x/pseudovariables
Is it maybe $ct or something else? :)
"$
I should have mentioned, please load the following modules:
loadmodule "textops.so"
loadmodule "textopsx.so"
then restart Kamailio.

Wow, cool, thanks! I added this snippet in the
request_route {
part, I hope that's correct. When I try to start Kamailio I get:
kamailio: Not starting : invalid configuration file!

Hi Alex,
I'm trying to replace the Asterisk box with an instance of
Kamailio+RTPEngine because the Asterisk box is heavily overloaded and
calls that are passing through this box are encountering packet loss.
The idea behind it is that the bundle of Kamailio+RTPEngine will be less
CPU-intense
You can start with the following:
# Change URI(s)
$ru = "sip:" + $rU + "@3.3.3.3";
$tu = "sip:" + $tU + "@3.3.3.3";
$fu = "sip:" + $fU + "@2.2.2.2";
$var(contact_username) = $cU;
# Remove existing Contact header
remove_hf("Contact");
# I
Hi Markus,
Can you elaborate upon the way in which you are using Kamailio+RTPEngine "as a
drop-in replacement"? Drop-in replacement for what? Or that is to say, what are
you trying to accomplish here, functionally?
I have the suspicion that what you're doing is probably best accomplished in a
Probably you need to modify only the RURI.
If you looking for a paid consultant you should post to the business
