Problem with register with expires to 0

[ralonsom]

If a terminal sends a registrer with exipres to 0 to unregister, the sbc sends it to the PBX, if the same terminal sends a new record again, the SBC only answers with 200 ok but does not send the new register to the PBX.

i have checked that when the record is sent with expires at 0 the register still appears in the location table.

Hi @ralonsom,

We have tried to reproduce the problem but OpenSIPS seems to be doing thing right for us:

• Normal register process every 60 seconds: OpenSIPS does register throttling as described here and only forwards to the main registrar when necessary.

• If a REGISTER with Expires header to 0 is received, it is forwarded to main registrar.

• If after a few seconds a new REGISTER is received with Expires to non-zero value, main registrar is updated again.

• Following renewals are not sent to main-registrar until the expiration between Opensips and main-registrar expires.

Any ideas? :thinking:

Hi @ralonsom ,

Could you please attach standard PCAP files so that we can analyze them more easily?
