Consider the following snippet:
if (is_present_hf("Contact")) { xlog("L_ALERT", "===== reply to SUBSCRIBE has Contact: $ct\n"); xlog("L_ALERT", "===== want to replace with $td\n"); xlog("L_ALERT", "===== regexp to use is /$sel(cfg_get.asterisk.bindip):$sel(cfg_get.asterisk.bindport)/$td/\n"); if (subst_hf("Contact", "/127.0.0.1:5080/$td/", "a")) { xlog("L_ALERT", "===== reply had Contact modified\n"); } }
If I use the hardcoded regexp "/127.0.0.1:5080/$td/", subst_hf() replaces the Contact value correctly.
However, if I use "/$sel(cfg_get.asterisk.bindip):$sel(cfg_get.asterisk.bindport)/$td/" (where asterisk.bindip and asterisk.bindport are the supposed values 127.0.0.1 and 5080), subst_hf() fails to replace the Contact value.
How do I make use of the existing configuration variables in order to substitute in the Contact header?
I haven't looked at the code, but probably the function doesn't accept variable for the matching regular expression.
If the IP/port of asterisk are not changed, you can try:
#!substdef "/ASTERISKIP/127.0.0.1/" #!substdef "/ASTERISKPORT/5080/"
asterisk.bindip = "ASTERISKIP" ... asterisk.bindport = ASTERISKPORT ...
subst_hf("Contact", "/ASTERISKIP:ASTERISKPORT/$td/", "a");
Cheers, Daniel

Apparently the search matched, and the replace was made. However, the replacement is incorrect:
Contact: sip:102@127.0.0.1:5080;alias=127.0.0.1~5080~1pbx.villacis.com;expires=3600
What I going on? Is the regexp incorrect? What I want for the Contact header is this:
Contact: sip:102@pbx.villacis.com;expires=3600
The documentation says the regexp is perl-style, and a sample running with perl shows the regexp to work correctly and to do what I want.

Apparently the search matched, and the replace was made. However, the replacement is incorrect:
Contact: sip:102@127.0.0.1:5080;alias=127.0.0.1~5080~1pbx.villacis.com;expires=3600
What I going on? Is the regexp incorrect? What I expected for the Contact header is this:
Contact: sip:102@pbx.villacis.com;expires=3600 or this: Contact: sip:102@pbx.villacis.com;alias=127.0.0.1~5080~1;expires=3600
...although I am not sure whether the latter is a valid header, but at least it would do something expected.
The documentation (http://www.kamailio.org/docs/modules/4.1.x/modules/textops.html#idp1655472) says the regexp is perl-style, and a sample running with perl shows the regexp to work correctly and to do what I want. I made a mistake when I mentioned that subst_hf() works correctly with the hardcoded regexp. What was really happening is that it does get accepted as a valid configuration, but displays unexpected behavior.

Would be nicer not to forward all headers inline, that results in a message easy to read (especially on mobile devices) and therefore faster to answer.
You use subst over contact and set contact allias, which both append values there, deleting same old content. Note that any change to sip message is not applied immediately, but kept as a diff operation. You need to use msg_apply_changes() after each change that you need to be visible immediately -- read the readme of textopsx for proper usage of this function.

I haven't looked at the code, but probably the function doesn't accept variable for the matching regular expression.
If the IP/port of asterisk are not changed, you can try:
#!substdef "/ASTERISKIP/127.0.0.1/" #!substdef "/ASTERISKPORT/5080/"
asterisk.bindip = "ASTERISKIP" ... asterisk.bindport = ASTERISKPORT ...
subst_hf("Contact", "/ASTERISKIP:ASTERISKPORT/$td/", "a");

Consider the following snippet:
if (is_present_hf("Contact")) { xlog("L_ALERT", "===== reply to SUBSCRIBE has Contact:$ct\n"); xlog("L_ALERT", "===== want to replace with $td\n"); xlog("L_ALERT", "===== regexp to use is /$sel(cfg_get.asterisk.bindip):$sel(cfg_get.asterisk.bindport)/$td/\n"); if (subst_hf("Contact", "/127.0.0.1:5080/$td/", "a")) { xlog("L_ALERT", "===== reply had Contact modified\n"); } }
If I use the hardcoded regexp "/127.0.0.1:5080/$td/", subst_hf() replaces the Contact value correctly.
However, if I use "/$sel(cfg_get.asterisk.bindip):$sel(cfg_get.asterisk.bindport)/$td/" (where asterisk.bindip and asterisk.bindport are the supposed values 127.0.0.1 and 5080), subst_hf() fails to replace the Contact value.
How do I make use of the existing configuration variables in order to substitute in the Contact header?

Thanks for the tip.
However, I also have an issue - subst_hf() does not seem to be working. Consider the following route, of which the snippet quoted above is a part:
# manage incoming replies onreply_route[MANAGE_REPLY] { # run rtpproxy resolution route(MHOMED_ELASTIX);
xdbg("incoming reply\n"); if(status=~"[12][0-9][0-9]") route(NATMANAGE); if (is_method("SUBSCRIBE") && route(FROMASTERISK)) { #xlog("L_ALERT", "===== reply to SUBSCRIBE, coming from asterisk, Call-ID is $ci\n"); $sht(pending_subscribe=>$ci) = 0; if (is_present_hf("Contact")) { xlog("L_ALERT", "===== reply to SUBSCRIBE has Contact: $ct\n"); xlog("L_ALERT", "===== want to replace with $td\n"); xlog("L_ALERT", "===== regexp to use is /$sel(cfg_get.asterisk.bindip):$sel(cfg_get.asterisk.bindport)/$td/\n"); if (subst_hf("Contact", "/127.0.0.1:5080/$td/", "a")) { xlog("L_ALERT", "===== reply hadContact modified\n"); } } } # manage websocket reply if (nat_uac_test(64)) { # Do NAT traversal stuff for replies to a WebSocket connection # - even if it is not behind a NAT! # This won't be needed in the future if Kamailio and the # WebSocket client support Outbound and Path. add_contact_alias(); }}

Apparently the search matched, and the replace was made. However, the replacement is incorrect:
Contact:sip:102@127.0.0.1:5080;alias=127.0.0.1~5080~1pbx.villacis.com;expires=3600
What I going on? Is the regexp incorrect? What I expected for the Contact header is this:
Contact:sip:102@pbx.villacis.com;expires=3600 or this: Contact:sip:102@pbx.villacis.com;alias=127.0.0.1~5080~1;expires=3600
...although I am not sure whether the latter is a valid header, but at least it would do something expected.
The documentation (http://www.kamailio.org/docs/modules/4.1.x/modules/textops.html#idp1655472) says the regexp is perl-style, and a sample running with perl shows the regexp to work correctly and to do what I want. I made a mistake when I mentioned that subst_hf() works correctly with the hardcoded regexp. What was really happening is that it does get accepted as a valid configuration, but displays unexpected behavior.

You use subst over contact and set contact allias, which both append values there, deleting same old content. Note that any change to sip message is not applied immediately, but kept as a diff operation. You need to use msg_apply_changes() after each change that you need to be visible immediately -- read the readme of textopsx for proper usage of this function.
Cheers, Daniel
Thanks, I will try this immediately. However, the call to add_contact_alias only runs if a websocket is detected, and I am having this issue over ordinary SIP through UDP.

Well, the alias parameter in contact is there, so one of the functions adding it is executed.
Maybe you can load debugger and enable cfgtrace to see what actions from kamailio.cfg are executed.
