[OpenSIPS-Users] Need help :: getting TM477 Error

[Ravindrakumar Bhatt]

Hello guys,
I need help to understand why am I getting below mentioned error and it's
possible solutions ?

Here opensips is listening to both IPv4 and IPv6 socket and one to one call
between IPv4 <--> IPv6,both IPv4 and Both IPv6 users is working fine,but
when I am trying to use call forwarding I am getting this error.
