SIP q parameter in REGISTER message


I have been told by my VoIP provider if I require two servers to register the same details I can supply a “q” parameter in the registration to allow them to determine the primary and secondary server.

Calls will be sent to the primary as long as it responds, otherwise they get sent to the secondary server.

Does anyone know how I can specify the q parameter in the register message? Is it possible?

Many Thanks,



Can anyone help me on this??

It would be really appreciated…
