Hi all,
I'm trying to implement a Click2Dial service by using the dlg_bridge command
from the dialog module. Although it works in this case, I found two problems
in the scenario and I would like to read your opinion about them.
1) Fisrt problem: the REFER generated by Kamailio doesn't contain a contact
header. As per RFC 3515, this request should have a Contact header. This
REFER is not being accepted by a proprietary device. This is can be worked
around with the append_hf() command from the textops module, but I don know
if it is a good solution.
2) The second one arises when the ACK generated by Kamailio, goes through
Kamailio (caller and calle involved in click2dial are registered on the
Kamailio server): the branch of the second via header is not correctly
populated. Its content is '0' when it must be tha same as in the INVITE.
Below you can find the traces of the whole scenario. Could you take a look
at them and give me your feedback?
Thanks in advance,
best regards
Antón Román
