[SR-Users] duplicated registrations

[Liu, Charles]

Hi Henning,

I have tried modparam("ims_registrar_scscf", "max_contacts", 1), but it does not seem to do anything. When doing multiple registration & re-registration, it still shows multiple contacts. I am using v 5.2.3, would this be a bug?


Thanks,

--Charles

Hello Liu,

You could e.g. use this parameter to restrict multiple registrations:

Cheers,

Henning

Hi All,

Does this look correct? I am using Zoiper client and did multiple registration/re-registration, but I saw duplicated contacts in the database for the same user/device(alice). I was expecting to see only one. Is this a bug? How do I prevent this happening?
