[OpenSIPS-Users] Why OpenSIPS sends 2 identical SIP INVITEs to a same peer?

[Rodrigo Pimenta Carvalho]

Hi.


I can see that OpenSIPS sends 2 identical SIP INVITE to a same peer. (When peer 5000 is called)

I know about it because wireshark shows that a peer is really receiving 2 INVITEs and also the OpenSIPS log shows:

Why such behavior can occur?

Could it cause some problem to my calls?


By the way, my location table has:

If there is 3 contacts, I guess I should see just 3 new branch, shouldn't I ?


Any hint will be very helpful!


Best regards.
