Hi Aydar,
Request from MS proxy has VIA: SIP/2.0/TLS 52.114.7.24:5061, that's where
your reply should go. You're sending to 52.114.7.24:1024 instead?
Also, looks like you're missing "r2=on" on the other RR, only one has it.
Cheers,

IMO, you should have only 2 of Kamailio, if you're doing transport

You're likely referring to this:
*Priority 1. Top-level Record-Route. If the top-level Record-Route contains
the FQDN name or IP, the FQDN name or IP is used to make the outbound
in-dialog connection.*
Like with many Microsoft products, nobody knows precisely what they expect.
To make matters worse - they don't reply back suggesting what's wrong, no
tools on their side to troubleshoot.
Regardless, why do you have 3 RRs of Kamailio? Fix the RRs, try again, or
don't, it's up to you.
Good luck.

Hi Aydar,
Request from MS proxy has VIA: SIP/2.0/TLS 52.114.7.24:5061, that's
where your reply should go. You're sending to 52.114.7.24:1024 instead?
Also, looks like you're missing "r2=on" on the other RR, only one has
it.
Cheers,

Again, MS says it expects FQDN in Contact.
If you are re-writing the Contact received from
ENDPOINT_BEHIND_KAMAILIO_IP, then I suggest you don't, it's sufficient to
have FQDN in RR. This isn't a "[certified] SBC", if it was like MS says -
it shouldn't work at all with a proxy like Kamailio.

Hi,
Like in Hennings howto described if the front facing Kamailio used the FQDN
names in contact and so one it works.
And the "must be an certified sbc" is an marketing foo and for support
cases they can say "go-to your sbc vendor" imho.
I had this setup up and running.
Kind regards

Again, MS says it expects FQDN in Contact.
If you are re-writing the Contact received from
ENDPOINT_BEHIND_KAMAILIO_IP, then I suggest you don't, it's sufficient to
have FQDN in RR. This isn't a "[certified] SBC", if it was like MS says -
it shouldn't work at all with a proxy like Kamailio.

You're likely referring to this:
*Priority 1. Top-level Record-Route. If the top-level Record-Route
contains the FQDN name or IP, the FQDN name or IP is used to make the
outbound in-dialog connection.*
Like with many Microsoft products, nobody knows precisely what they
expect. To make matters worse - they don't reply back suggesting what's
wrong, no tools on their side to troubleshoot.
Regardless, why do you have 3 RRs of Kamailio? Fix the RRs, try again, or
don't, it's up to you.
Good luck.

_______________________________________________ You have too many RR of Kamailio, x1 FQDN, x3 IP.
Why?
IMO, you should have only 2 of Kamailio, if you're doing transport
conversion. Both FQDNs + ";r2=on". MS clearly says FQDN everywhere, no IP,
especially RR

The FQDN must be in the Contact of the OPTIONS request that is used for the
trunk keep alive. No need to mess up with the Contact header for in dialog
requests/replies.
However, the FQDN must be in the Record-Route header facing MS for in
dialog requests/replies.

Hi,
Like in Hennings howto described if the front facing Kamailio used the
FQDN names in contact and so one it works.
And the "must be an certified sbc" is an marketing foo and for support
cases they can say "go-to your sbc vendor" imho.
I had this setup up and running.
Kind regards

Again, MS says it expects FQDN in Contact.
If you are re-writing the Contact received from
ENDPOINT_BEHIND_KAMAILIO_IP, then I suggest you don't, it's sufficient to
have FQDN in RR. This isn't a "[certified] SBC", if it was like MS says -
it shouldn't work at all with a proxy like Kamailio.

You're likely referring to this:
*Priority 1. Top-level Record-Route. If the top-level Record-Route
contains the FQDN name or IP, the FQDN name or IP is used to make the
outbound in-dialog connection.*
Like with many Microsoft products, nobody knows precisely what they
expect. To make matters worse - they don't reply back suggesting what's
wrong, no tools on their side to troubleshoot.
Regardless, why do you have 3 RRs of Kamailio? Fix the RRs, try again,
or don't, it's up to you.
Good luck.
