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?
