Hello, we have faced an issue which appears when TOPOH module is enabled, call
is made from WebRTC client, then transferred by callee.
We have WebRTC client behind load balancer. We make call to softphone from
WebRTC, call from softphone is transferred to external number using Asterisk.
When call is hanged up on external number side, it doesn't hangs up on WebRTC
client side.
If TOPOH is not enabled, this issue doesn't occur.
We have the following TOPOH-related sections of kamailio.cfg:
<...>
#!ifdef WITH_TOPOH
loadmodule "topoh.so"
#!endif
<...>
<...>
#!ifdef WITH_TOPOH

modparam("topoh", "uparam_prefix", "")
modparam("topoh", "vparam_prefix", "")

(can provide the full config, if needed)
We are receiving the following errors:
On transfer:

On hangup from external number side:

On hangup from WebRTC client side:

There are also differences in SIP traffic when TOPOH is disabled and when it is
enabled. With TOPOH enabled, apparently, ACK from Asterisk is not reaching
kamailio:
asterisk INVITE -> kamailio -> WebRTC
WebRTC 200 -> kamailio -> asterisk
asterisk ACK -> kamailio -> -> ->
