wiki was this related to $(hdr(name)[N]):
If [N] is omitted then the body of the first header is printed. The first header is got when N=0, for the second N=1, a.s.o. In case of a comma-separated multi-body headers, it returns all the bodies, comma-separated.
i don't understand the last sentence. how can i get all bodies of all headers of name=x as a comma separated list?

perhaps the above "In case" sentence should read:
In case of comma-separated multi-body headers, $(hdr(name)[*]) returns all the bodies, comma-separated.
while testing this, i found a bug. when incoming request has
Test: sip:user1@foo.bar. Test: sip:user2@foo.bar,sip:user3@foo.bar.
xlog("L_INFO", "Test '$(hdr(test)[*])'\n");
produces:
Apr 25 17:11:37 siika /usr/sbin/sip-proxy[9801]: INFO: Test 'sip:user1@foo.bar, sip:user2@foo.bar,sip:user3@foo.bar'
the bug is the extra space char after first comma.

I guess the $hdr(X[*]) uses comma-space for separation (haven't checked the sources). In your example, the second header test has two values in one line and $hdr(...) is simply returning all of them.
If you would have:
Test: sip:user1@foo.bar. Test: sip:user2@foo.bar,sip:user3@foo.bar. Test: sip:user4@foo.bar. Probably the result would be:
'sip:user1@foo.bar, sip:user2@foo.bar,sip:user3@foo.bar, sip:user4@foo.bar'

since there is no need for space, it should not be there.

It can be removed.

i looked at the source and found in pv_core.c/pv_get_hdr() this:
memcpy(p, PV_FIELD_DELIM, PV_FIELD_DELIM_LEN);
the constants:
#define PV_FIELD_DELIM ", " #define PV_FIELD_DELIM_LEN (sizeof(PV_FIELD_DELIM) - 1)
are used all over the place and it would thus not be a good idea to edit them. perhaps adding a new ones:
#define PV_HDR_DELIM ", " #define PV_HDR_DELIM_LEN (sizeof(PV_HDR_DELIM) - 1)
would be ok.

New ones can be added, indeed. Cheers, Daniel

It is related to headers like:
H: v1, v2 H: v3
$hdr(H) returns 'v1, v2'.
