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
