Re: [SR-Users] SIP OPTIONS between UE and P-CSCF

Hello,

is Kamailio listening on other sockets towards UE other than the IPSec tunnel?

Cheers, Daniel

Hi

We have setup UE with Kamailio IMS, and after the registration is successful. The 2nd SIP REGISTER is sent from UE to P-CSCF through IPSEC tunnel.

But we found that the SIP OPTIONS (I believed it is a health check) from P-CSCF to UE is not through the IPSEC tunnel.

our question is

1. Should SIP OPTIONS run inside the IPSEC tunnel or it should be outside?
2. if it can be configured to run inside the IPSEC tunnel, what

configuration can we change to achieve it?
