[SR-Users] Parameters list transformations comma and semi column conflict

[Peter Dunkley]

Hello,

Parameters to SIP headers are ';' separated.  ',' is used to concatenate
multiple headers onto a single line.  The {param...} transformation is
intended to process SIP header parameters.

However, there is a new feature in Kamailio 4.1 (currently in a
pre-release/testing phase) that allows you to specify the delimiter value.
 That may do what you require.

Please see:

Regards,

Peter
