Hello Patrick,

then you probably need to change the code of Kamailio.

The length of the Via branch parameter is not restricted in RFC 3261. The relevant section only states:

https://www.rfc-editor.org/rfc/rfc3261#section-8.1.1.7

The branch parameter value MUST be unique across space and time for all requests sent by the UA. [..] The branch ID inserted by an element compliant with this specification MUST always begin with the characters "z9hG4bK". [..] Beyond this requirement, the precise format of the branch token is implementation-defined.

Cheers,

Henning

Hello,

not sure why one wants to do this, but anyway - do you mean the value that is processed from Kamailio, or the one that is generated from Kamailio?

Cheers,

Henning
