Hello,
In a standard sip flow, the call goes like: sip user A -->
kamailio --> pstn --> landline user B. However, when user A has a bad
internet access, the audio is broken. So what I want is to let sip
user A send a invite to kamailio first, then kamailio send invite to
user A and B's landline number through pstn, then bridge the two call
together.
I understand this can be achieved by using FREESWITCH originate
and bridge command. I've tried but there's no audio both ways, which
really makes me feel stupid of myself. So I'm wondering if this can be
done with kamailio? If so, how?
kamailio cannot bridge a call like freeswitch does,
because kamailio
doesn't handle media stream.
The only option that you can do in kamailio to connect two phones is to
rely on REFER for doing a call transfer. See dialog module and dlg
bridge feature from there, maybe it is enough for what you want to achieve.
Cheers,
Daniel
