[OpenSIPS-Devel] [opensips] Fail to register after a reboot, with error 'Invalid CSeq number' (#641)

[was4444]

Hi, @bogdan-iancu,

In my scenario, the UAC always registering to the registrar with the same call-id, which seems do not have any problems, according to the [rfc](https://tools.ietf.org/html/rfc3261#section-10.2).

But after a reboot(within the expire-time), the UAC then try to register with a very low CSeq with the same call-id, then the server rejects the registration. This, also, seems nothing wrong.

But then comes the problem, my UAC cannot register in a period of time according to it's previous expire-time.

So, must the UAC initiate a new call-id in the very every beginning? The [rfc](https://tools.ietf.org/html/rfc3261) does not say anything about this.
