### Description
We have faced an issue which appears when TOPOH module is enabled, call is made from WebRTC client, then transferred by callee.
#### Scenario
WebRTC client behind load balancer makes call to softphone, call from softphone is transferred to external number using Asterisk.
#### Expected result
When call is hanged up on external number side, call should be hanged up on WebRTC client side.
#### Actual result
When call is hanged up on external number side, call is not hanged up on WebRTC client side.
### Troubleshooting
#### Legend
10.5.0.145 - load balancer 10.128.150.67 - WebRTC client 10.181.0.1 - kamailio 10.5.2.192 - asterisk
