Hi,

Thanks for your reply.

 

Maybe my problem definition is not fully clear:

For my use case, having addtional configuration on the SIP UA (softphone) side is not feasible. I am looking for solution on the Freeswitch side(sitting on the public network). Not all SIP UA clients (softphones) will have the solution of working around NAT, let alone STUN client support.

 

I observed the Freeswitch has some features like AutoNAT etc. Aren't these of any help for the use case i have ? I just started reading on the AutoNAT feature. The documentation of AutoNAT seems to suggest that freeswitch itself sits behind a NAT. This is not the same as my use case.

 

To summarize: Does freeswitch have any method of detecting that the remote SIP UA is behind a NAT and taking some action based on that ?

Any suggestions are welcome.

 

thanks,
