Hi Some UAs do not support PRACK or UPDATE and still work fine with various Proxies, PBX, Softswitches etc. Are there any scenarios or well known Proxies,Softswitches that require mandatory PRACK and UPDATE support for a UA to be interoperable? Or maybe some features will not be available if support for these methods is not there.
Just trying to understand where PRACK and UPDATE are used. Thanks _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
