Hi,
Thanks but I tried that and whatever I tried I could not get it to
work. I don't know whether I have misunderstood what you meant?
With this setup:
+------+----+----------+----------------+-------------+-------------+-------------+
| dpid | pr | match_op | match_exp | match_flags | subst_exp | repl_exp
|
+------+----+----------+----------------+-------------+-------------+-------------+
| 100 | 1 | 1 | (;user=phone)? | 1 | ;user=phone |
;user=phone |
+------+----+----------+----------------+-------------+-------------+-------------+
I got this:
# opensips-cli -x mi dp_reload
"OK"
# opensips-cli -x mi dp_translate 100 "+12...@sip.com;food=beans"
ERROR: command 'dp_translate' returned: 404: No translation
# opensips-cli -x mi dp_translate 100 "+12...@sip.com;user=phone"
{
"Output": ";user=phone",
"ATTRIBUTES": ""
}
and with this setup:
+------+----+----------+----------------+-------------+----------------+-------------+
| dpid | pr | match_op | match_exp | match_flags | subst_exp |
repl_exp |
+------+----+----------+----------------+-------------+----------------+-------------+
| 100 | 1 | 1 | (;user=phone)? | 1 | (;user=phone)? |
;user=phone |
+------+----+----------+----------------+-------------+----------------+-------------+
I got this:
# opensips-cli -x mi dp_reload
"OK"
# opensips-cli -x mi dp_translate 100 "+12...@sip.com;food=beans"
{
"Output": ";user=phone",
"ATTRIBUTES": ""
}
# opensips-cli -x mi dp_translate 100 "+12...@sip.com;user=phone"
{
"Output": ";user=phone",
"ATTRIBUTES": ""
}
but also realised that if it had matched, I would have no control over
where in the URI it would have added the extra text, so I'm wondering
that my two rule approach is perhaps the best way for what I'm doing
anyway.
Cheers,
Kingsley.
