Hi all,<br><br>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.<br>
<br>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. <br>
<br>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. <br>
<br>Below you can find the traces of the whole scenario. Could you take a look at them and give me your feedback?<br><br>Thanks in advance,<br>best regards<br><br>Antón Román<br><br><br>T +8.969957 <a href="http://127.0.0.1:44785" target="_blank">127.0.0.1:44785</a> -> <a href="http://127.0.0.1:5060" target="_blank">127.0.0.1:5060</a> [AP]<br>
