> If I configure my pjsip transport to handle NAT from the Internet:
> {noformat}
> [transport-tcp]
> type=transport
> protocol=tcp
> bind=10.75.22.8:5060
> local_net=10.75.22.0/24
> external_media_address=[external address redacted]
> external_signaling_address=[external address redacted]
> {noformat}
> When a call comes from a TCP registered SIP client on the Internet,
> Asterisk is setting the IPv4 address in the {{o=}} and {{c=}} lines of the
> SDP ICE payload to {{(null)}}:
> {noformat}
> v=0
> o=- 3654 548 IN IP4 (null)
> s=Asterisk
> c=IN IP4 (null)
> {noformat}
> IPv4 addresses in all of the {{a=}} lines are still correct.
> This {{(null)}} of course causes the caller to fail to complete the call.
