[SR-Users] Topoh module & call leg/transaction does not exist

[Olli Attila]

Hello,

The B party (IP: 37.219.148.155) is the one that sends the bye. A party 
(IP: 178.75.176.146) will never see this bye because Kamailio (IP: 
193.28.89.162) in the middle replies to B party with 481. The result is 
that A partys softphone thinks the call is still online.

This can be seen on the kamailio_5-0_sip481.pcap trace.

Cheers,

--Olli
