Re: [reSIProcate-users] SIP messages limits for UDP in reSIProcate

[Scott Godin <sgodin@xxxxxxxxxxxxxxx>]

There is nothing in the stack today to automatically switch from UDP to TCP based on the message size.  The application would need to be responsible for that.  You may want to consider just enabling TCP only.  

Sounds like a feature to consider for a future release.  :)

Hi,

 

    I noticed in my UA application that the dum/resiprocate stack is sending and receiving UDP packets well above the 1300 bytes limit recommended in RFC3261.  (e.g. 5000 bytes)

   

    I think that allowing SIP over UDP above 1300 bytes is an useful behaviour in some scenarios (despite RFC3261) but undesirable in others.

    

    Suppose I have activated both UDP and TCP transports in an UserAgentMasterProfile.

    Is there any configuration to select the behaviour between "allow any UDP datagram size" and "switch automatically to TCP when sending SIP message above 1300 bytes" ?

   

    I am using reSIProcate 1.8.14 in Windows 7.

 

   

Best Regards,

Julio.
