Hi Kingsley,
You could try with a single rule, like optional matching the param (like
"(;user=phone)?") and in subst + repl part do not include the param
inside the \1 parenthesis, having it added all the time in the repl part.
Still you need a more complex matching if you have multiple params, not
only the "user" one.

Hi,
I want a DP ruleset to ensure that ";user=phone" is in the SIP URI, ie
if it is not there, add it, but if it is already there, do nothing.
I've managed to do this with two lines, but is there a more efficient
way?
This is what I have in the dialplan table in this ruleset?
+----+----------+-------------+-------------+-----------+---------------+

| 1 | 1 | ;user=phone | 1 | (.+) | \1 |
| 2 | 1 | . | 1 | (.+) | \1;user=phone |
