remove_hf doesn't seem to work in route[b2b_reply]....Running OpenSIPS 1.11.5
on CentOS 6.
This problem started when I discovered that b2b_init_requests removes the user
part of the URI in the Contact: field.
To correct that, did a bit of scripting to correct the outgoing invite:
First, handle contacts manually:
modparam("b2b_logic", "custom_headers",
"Priority;Calluid;Geolocation;Geolocation-Routing;Contact")
Second, check out the incoming INVITE, and modify the host part to be the
OpenSIPs server itself (192.168.130.105):
$var(ContactURI)=$ct.fields(uri);
$var(ContactURIHost)=$(var(ContactURI){uri.host});
$var(ContactURIUser)=$(var(ContactURI){uri.user});
$var(regedit)="/"+$(var(ContactURIHost))+"/192.168.130.105/g";
$var(URIwSub)=$(var(ContactURI){re.subst,$var(regedit)});
Third, in local_route, remove the incoming contact and replace with my own:
remove_hf("Contact");
append_hf("Contact: $var(URIwSub)\r\n");
Fourth, send off the invite downstream (to 192.168.131.203):
b2b_init_request("FailOver", "sip:[email protected]");
All this works! Great, but the reply route, not:
route[b2b_reply] {
xlog("b2b_reply Route ($ci)\n");
###Debug Code

xlog(">>>>>B2BRR:Contact methods:$ct.fields(methods)\n");
xlog(">>>>>B2BRR:Contact params:$ct.fields(params)\n");
$var(ContactURIRR)=$ct.fields(uri);
$var(ContactURIHostRR)=$(var(ContactURIRR){uri.host});
$var(regeditRR)="/"+$(var(ContactURIHostRR))+"/192.168.130.105/g";
$var(URIwSubRR)=$(var(ContactURIRR){re.subst,$var(regeditRR)});
if(remove_hf("Contact"))
{
xlog(">>>>>B2BRR:removed Contact\n");
} else {
xlog(">>>>>B2BRR:DID NOT removed Contact\n");
};
#
# xlog("Substituted Contact URI Variable Reply Route:$var(URIwSubRR)\n");
append_hf("Contact: $var(URIwSubRR)\r\n");
#replace_body_all("Contact", "BlaBla");
}
So in route[b2b_reply], do the same treatment as in the invite. The xlog says
that it did remove the Contact, but it's still there, according to wireshark.
The append_hf works fine, but the remove_hf never works. I end up with 2
Contact.
Any ideas?
