[OpenSIPS-Users] Receiving TM 477

[Ravindrakumar Bhatt]

Hello,

I apologize for earlier half mail done by mistake . I am using opensips
2.2.3 within centos7.

Opensips is listening on IPv4 and ipv6 sockets.I am getting below shown
error when i try call forwarding.

Scenario is :

user1(IPv6) -> user2(IPv6) ->call forward to user3(IPv4)

Sep 13 13:18:45 host60-190-60-195 /usr/local/sbin/opensips[134236]:
ERROR:core:proto_udp_send:
sendto(sock,0x7f1da1c8a940,2300,0,0x7f1da1ca9698,16):

Sep 13 13:18:45 host60-190-60-195 /usr/local/sbin/opensips[134236]:

Sep 13 13:18:45 host60-190-60-195 /usr/local/sbin/opensips[134234]: This is
handle_nat reply route: 477

please note i am getting this error in only this scenario in other cases
its working fine.so what is the reason behind this and how does bridging
between ipv4 and ipv6 works?
