I notice that during a dialog session from a UA to the server going to the PSTN gateway, it was refering to this Call-ID until the point when the request was forwarded to the PSTN gateway. When the PSTN gateway replies, it replied with a same Call-ID with a different IP address at the back (9ce97fd3-1a800040@123.234.123.234 mailto:9ce97fd3-1a800040@123.234.123.234 )
That is very wrong. Maybe there is an ALG in the path which replaces the private address with public ones, but that should not apply to the call-id. The caller should reject the reply.
I have actually seen an ALG do exactly that before, and my client dropped all messages coming back through it, as expected.
