Hi,
It’s possible that the
Xten softphone detects that the second INVITE is part of a cleared session (the
first INVITE rejected with 400 error), and discards it….

Asunto: [Serusers] Re-routing to
same device in failure_route
Hi
Group,
Cisco 5300 -----> SER ----> Xten softphone-A ----> Failed call with
error code >400 -------> try to route to Xten softphone A(same as
previous)
I am trying to route calls to softphones in such way that, if call failed by
some reason (>400), trying to route second time to the same soft phone using
append_brach() and t_relay() like below. But, soft phone is unable process
INVITE message for some reason. But, if I forward failed call different
soft phone, call was successful.
Am
I doing any thing wrong in config ???
Thanks
for your help in advance.
Regards,
Karun
