[SR-Users] Unregister with Multiple Contacts

[David Villasmil]

Beware that since you’re removing all contacts, if any are valid and if any
of the contacts that did not unregister is called, Kamailio won’t find them.

If what you need is not force only one contact per user, maybe look at
http://www.kamailio.net/docs/modules/5.4.x/modules/registrar.html#registrar.f.save
