"IP association no match, user not registered"

FreeSWITCH Troubleshooting

Hello,

My freeswitch instance registers with the ISP sip server (Nokia/Siemens server). The minimum expiry interval set by the ISP is 900 seconds (15 minutes), which causes the pfsense instance to lose the connection. I tried to setup OPTIONS with a lower interval but the ISP returns the following,

What do i need to pass in the options string for the ISP to accept?

Thanks

It depends what provider requires. Here’s a link to several provider settings for registering Providers ITSPs | FreeSWITCH Documentation It may give you and idea of what other providers require that could be close to what Nokia/Siemens need. From the error it looks as you’re not registered. Warning: 399 uea37.org "IP association no match, user not registered"

The end point is indeed registered and sofia status gateway confirms that. However, OPTIONS seem to trigger that response.

Here is the log sip log. The sip end point registers fine, but OPTIONS doesnt work.

You should open a ticket with the provider as to why they are not accepting the OPTIONS, and confirm that they even accept OPTIONS in the first place.
