We have Kamailio-cluster via route53(round-robin) some-domain.net
we have two kamailio with public IP's
phone1 is registered on kam1
phone2 is registered on kam2
when we are calling from phone1 to phone2 callflow looks:
phone1 => kam1 => asterisk => kam1 => t_relay(address of second
kamailio:5078) => kam2 => phone2
it works perfectly, but in case when we are using polycom as phone2 - we are
getting 404 response from polycom...

Hi Zhan,
At first glance, it does not appear that anything about the second
request is grammatically invalid.
I suspect the problem you are encountering is UDP fragmentation, as
explained in my blog post here:
http://www.evaristesys.com/blog/sip-udp-fragmentation-and-kamailio-the-sip-…
The size of the second INVITE you pasted is 1198 bytes. Add 463 bytes of
encapsulated SDP body (Content-Length header), and it's 1661 bytes -
over the UDP fragmentation threshold of ~1480 based on an MTU of 1500
bytes.
This is due to the additional "contributions" of the second Kamailio -
extra Via and Record-Route headers. Removing these extras probably puts
the message length at just under the fragmentation threshold.
Because the receiver does not get a fully reassembled UDP datagram, the
message arrives partly formed (first UDP fragment is the only one
received), the Polycom's SIP stack is confused.

Is it possible to get a log, sip trace or even a capture for wireshark
out of the phone?
That may reveal more about what had happened.
