[OpenSIPS-Users] No record-route on reply's

[Mike Tesliuk]

Hello Guys,


Im getting a strange situation here that i dont know how to deal

i have an enviroment where i have freeswitch receiving a call to billing
and opensips doing the load_balance to the gateways.

When i send the call to the gateway i receive the reply without the
record-route header, i try to put  an asterisk server as gateway and this
not happen in this scenario .

Below the invite that i send to the gateway

U 10.1.69.1:5079 -> 10.255.2.31:5031
