Hi all Below is an excerpt from RFC5626; " The sequence of reg-id values does not have to be sequential but MUST be exactly the same sequence of reg-id values each time the UA instance power cycles or reboots, so that the reg-id values will collide with the previously used reg-id values. This is so the registrar can replace the older registrations. "
The sequencing of reg-id helps to remove the prev registered contacts, in case, the UA reboots after crash. Pl correct me. Should reg-id be same with respect to outbound-proxy-set also? i.e. The reg-id that is used for Proxy-1 must be same even after reboot. Say, User first registers with P1 as primary and P2 as secondary and the reg-id starts from 1. User registers. UA crashes and the user reboots now with P2 as primary and P1 as secondary. i. Should the REGISTER, sent to P2, have reg-id as 2 or ii. shall it be 1? Pl clarify. Thanks in adv.
