Re: [SR-Users] Same Via Tag for INVITE and ACK on S/L loadbalancer

ACK for successull response is a new transaction. It has to be different. May be it is better to point provider to this?  On Mon, 10 Feb 2020, 14:26 Sebastian Damm, &lt;damm(a)sipgate.de <mailto:damm@sipgate.de>> wrote: Hi, I stumbled upon an interop problem with a carrier. We have the following scenario: Gateway --> Loadbalancer --> Carrier The loadbalancer generates a Via header for each request. But since it is stateless, the Via tag is generated for each request. As a consequence, the Via tag in the ACK differs from the one in the INVITE. And one carrier doesn't handle those ACKs if the Via tag differs. Is there a way to force the creation of a "deterministic" Via branch tag? For example, building it from a hash over call-id and from-tag or something like that?
