ASBCE change Contact Header

[OmegaStar]

Hello everyone,

can some one tell how i can change wíth the Sigma script the Contact Header? i have the Problem that anonymous calls don't go out because the Provider gives a 403 forbidden.

PBX: IPO
SBC: Avaya SBC
Provider: Telekom Deutschland
Product: CompanyFlex

Sigma script
within session "INVITE"
{

act on message where %DIRECTION="OUTBOUND" and %ENTRY_POINT="POST_ROUTING"
{

{
remove(%HEADERS["History-Info"][3]);
remove(%HEADERS["History-Info"][2]);
remove(%HEADERS["History-Info"][1]);
remove(%HEADERS["From"][1].DISPLAY_NAME);
remove(%HEADERS["Contact"][1].DISPLAY_NAME);
append(%HEADERS["Contact"][1],"+49199296000000xxxxx@tel.t-online.de");
remove(%HEADERS["P-Asserted-Identity"][2]);
remove(%HEADERS["Contact"][1].URI.PARAMS["epv"]);
remove(%HEADERS["Contact"][1].URI.PARAMS["gsid"]);
remove(%HEADERS["P-Location"][1]);
remove(%HEADERS["Server"][1]);
remove(%HEADERS["User-Agent"][1]);
remove(%HEADERS["Session-ID"][1]);
remove(%HEADERS["Recv-Info"][1]);
remove(%HEADERS["Accept-Contact"][1]);
}
}
}

The simplest way would be:
%HEADERS["Contact"][1].URI.USER = "+4919929600000xxxxx";
So instead of appending just set the user part to whatever you want.

If you have to change the domain as well do this:
%HEADERS["Contact"][1].URI.HOST = "tel.t-online.de";

Alternatively, you can combine both by changing the complete URI, not the USER and HOST individually:
%HEADERS["Contact"][1].URI = "+4919929600000xxxxx@tel.t-online.de";

What exactly is needed in the contact header?

 

[OmegaStar]

this here append(%HEADERS["Contact"][1],"+49199296000000xxxxx@tel.t-online.de");

But IP Office usually sends a contract header. So no need to append one.

 

[OmegaStar]

Yes that was my first Problem but now with a anonymous Call it sends not the correct Contact informations

 

[Alfalis]

As I said:
%HEADERS["Contact"][1].URI.USER = "+4919929600000xxxxx";

 

[OmegaStar]

As I said:
%HEADERS["Contact"][1].URI.USER = "+4919929600000xxxxx";

what should I write for %HEADERS? add or append?

 

[Alfalis]

Nothing, that is what you need in your SigMa script. That is the syntax

What @Alfalis tells you is that this piece of the sigma script set the user part of the contact header to the CompanyFlex Username. Regardless what is received by IPO. As the header is already there it makes no sense to add or append anythin.

Hallo Florian, ich schreibe es mal auf Deutsch. Bei einen Normalen Anruf wird der richtige Contact Header mitgeschickt aber bei einen Anruf wo die Rufnummer unterdrückt wird, wird nicht der richtige Contact Header mit geschickt. Mit %HEADERS["Contact"][1].URI.USER = "+4919929600000xxxxx"; funktioniert es jetzt.

Wie gesagt, es gibt einen Header. Es ist nicht nötig, zusätzlichen (add/append) Header hinzuzufügen.

As mentioned… there is already a header available from IPO. No need to add another contact header (add/append).
