The SIP dialog is not identified by the Call-ID alone. From and To are also part of the tuple.

So although they share a Call-ID the From and To headers are different, therefore they are different SIP dialogs (calls).

Thanks, Brian,

i think i have resolved my issue (a stupid FW ports issue ...), but still interested to understand if this call flow can lead to issues on Freeswitch (doesn't seem to be the case, as I really see freeswitch managing two independant calls).
How can i send you a pcap ?

What do you mean exactly by “managed”?

They are not the same call. Every time a call is created in FS, FS created a unique UUID, and that’s what is used by Fe to manage the call I question.

So when you create an outbound call. It has an associated UUID, and when the same call is sent to you by the proxy, it created another UUID.

You treat them as different calls altogether.

  Hi all,

currently working to understand some calls without RTP (one-way audio, or no audio at all), I noticed a strange case in our traces : we send an outgoing call on a trunk. The destination number is translated to another number, and the call comes back to our SBC (the new dest is on our network).
What i noticed is that the incoming call has the same call-id as our outgoing call (I suppose that the other operator uses proxies rather than SBCs), and it comes to the same freeswitch (has 2 IP addresses)

So, wondering what could be the impact of that on our Freeswitch SBC.
Can those 2 calls be managed as one and only call by freeswitch ?

Thanks with anticipation
Best regards,

Dominique Jeannerod
