Hello,
pbx -> kamailio -> provider
kamailio registers (uacreg) on provider.
When I call through my provider I need to change headers To From and PAI. I
tried with uac_replace_from and uac_replace_to.
$tU for example 0987656789
if($fU=~"1234567") {
uac_replace_from("sip:provider_login@provider.com");
uac_replace_to("sip:$tU@provider.com");
}
My provider answers on Invite with 183 progress, so pbx answers with PRACK.
Kamailio change To and from like this:
To: <sip:0987656789@provider.comsip:0987656789@provider.com
;tag=.....
To:
<sip:0987656789@provider.comsip:0987656789@provider.com>
From: <sip:provider_login@provider.comsip:provider_login@provider.com
;tag=.....
From:
<sip:provider_login@provider.comsip:provider_login@provider.com>
Is it a bug?
I tried to disable this modification for PRACK u REQINIT ($csb != "2
PRACK") It haven't worked for me.
I solved this issue with this code.
remove_hf("From");
if ($ft == $null) {
insert_hf("From: <sip:provider_login@provider.com>\r\n",
"To");
} else {
insert_hf("From: <sip:provider_login@provider.com>;tag=$ft\r\n",
"To");
}
version: kamailio 5.7.0-dev0 (x86_64/linux)
Ubuntu 18
