[OpenSIPS-Users] Working with MAX-FORWARDS in B2B topology hidding

[Алексей Хамстр]

Hello.
Please tell me who faced the setting of the MAX-FORWARDS parameter pass
when using the B2B module
We have found that when using the module, this counter starts counting
again from the initial value of 70, which leads to looping of calls in the
network.
example from trace

in the input of opensips we have

INVITE sip:543174317 at 94.241.67.137 SIP/2.0
*Max-Forwards: 18*

but on the output there is:

The module documentation says that this header should be passed from the
dialog of one side to the other side.
Max-Forwards (it is decreased by 1)

Thanks in advance,
with regards,
