Hi there,
I'm trying to use the Sofia-SIP library to perform an unattended call
transfer. E.g. If I'm A and in a call with B and C, I thought I could
transfer so that B and C are talking with something like:
sip_replaces_t *replaces = nua_handle_make_replace(nua_
handle_B, NULL, 0);
nua_refer(nua_handle_B,
SIPTAG_REFER_TO_STR(addr_C),
SIPTAG_REPLACES(replaces),
TAG_END());
However, when I do this I immediately get a nua_r_refer/400/"Replaces
header not allowed", and no further action is taken.
I'd appreciate it if someone could point out my error, or what I can
do to get around this.
Thanks,
John Graham
