[OpenSIPS-Users] Calls being disconnected

[Rodrigo Ferreira]

I’ve a lot of different scenarios through my network, I have clients behind NAT, from other networks, because I work for a telephony company.

RTPproxy - thats what I suspected. What i'm guessing is that RTPproxy is engaged but somehow the end points receive each other's Direct IPs in SDP...hmm...tell me if your both end points are on the same LAN and server is placed somewhere in internet !!

  Besides logs and any sip traces as Aamir stated it'd be hard to pin point anything. One of the big reason for automatically dropping an established call specially after a specific amount of time i.e 30 seconds..thats because of lack of RTPs flowing through the server and if media-relaying tools are used they will send hangup to both ends, even though both ends have their RTP flowing directly.

    Hi Rodrigo,


    The only which I know is after the call gets connected i.e. 200OK from the other end there should always be an ACK for that 200OK, if there is no ACK for the 200OK then the call will get disconnected after sometime.


    Can you please give us the logs for the call by tracing it through ngrep tool because without any sip traces or opensips log we can't tell what is going on within the box.

    Hey guys,

    I’m having problems with calls being “disconnected” and I dont know where I can start to look at, because on my CDR all those calls ends with a 200OK, but that isnt true, because you are talking all the suddenly the call stop.

    Any ideas where I should start looking at?
