Is there a good way to work around a broken NAT?
I have a customer who is receiving one-way inbound audio (outbound is fine).
Here's what a REGISTER packet looks like:
U public.ip:9241 -> opensips.ip:5060
REGISTER sip:registrar SIP/2.0..Via: SIP/2.0/UDP
<sip:0882 at registrar.warp2biz.com>;tag=98193b5f9af29c75o0..To:
"626-628-0882" <sip:0882 at registrar>..Call-ID: 1fc928db-41d9
2937 at 192.168.1.71..CSeq: 50366 REGISTER..Max-Forwards: 70..Contact:
"0882" <sip:0882 at public.ip:9241>;expires=3500..User
0..Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS,
As you can see, all nat_uac_test()s would fail, and nothing is stored
in the received line of the location database.
Is there another way to work around this, or do I just have to tell
them to fix their router?
