I found a way to do it. Just in case if somebody is interested:
su_home_t home[1] = { SU_HOME_INIT(home) };
sip_unknown_t* unknown_headers = NULL;
sip_unknown_t* prev = NULL;
std::vector<std::string, std::string>::const_iterator it =
custom_headers.begin();
for(; it != custom_headers.end(); ++it)
{
sip_unknown_t* current = sip_unknown_format(home, "%s: %s",
it->first.c_str(), it->second.c_str());
if (unknown_headers == NULL)
unknown_headers = current;
current->un_next = NULL;
if (prev != NULL)
prev->un_next = current;
prev = current;
}
nua_invite( nh,
SIPTAG_UNKNOWN(unknown_headers),
TAG_END());
su_home_deinit(home);

Subject: Can I use SIPTAG_UNKNOWN_STR with nua_set_hparam?
The following approach works, the unknown header (header: value) is actually in
the INVITE message:
1.
nua_handle(nua, NULL, SIPTAG_TO(blah), SIPTAG_UNKNOWN_STR("unknown: value"),
TAG_END()); nua_invite(handle, SOATAG_USER_SDP_STR(sdp), TAG_END());
2.
nua_handle(nua, NULL, SIPTAG_TO(blah), TAG_END()); nua_invite(handle, ),
SOATAG_USER_SDP_STR(sdp), SIPTAG_UNKNOWN_STR("unknown: value"), TAG_END());
But setting unknown header with nua_set_hparams() doesn't seem to be working.
The INVITE message was sent without the header:
nua_handle(nua, NULL, SIPTAG_TO(blah), TAG_END()); nua_set_hparams(handle,
SIPTAG_UNKNOWN_STR("unknown: value"), TAG_END()); nua_invite(handle,
SOATAG_USER_SDP_STR(sdp), TAG_END());
Is this behavior intended? If it is, I need to set multiple unknown headers in
runt time so is there another way to do it?
I am using version version 1.12.11 on Windows 7 64 bit.
