I'll try the patch and let you know the result. I also paid attention that 'topoh' modifies the 'via' header field of the request. It inserts the "TH=div" parameter: Original request: ``` INVITE sip:9992003@leotst.weyl.in.xorcom.com:5060 SIP/2.0^M Via: SIP/2.0/UDP 192.168.6.108:5260;rport;branch=z9hG4bK2821386093^M ``` the forwarded request: ``` INVITE sip:9992003@leotst.weyl.in.xorcom.com:5060 SIP/2.0^M Record-Route: sip:10.197.184.1;r2=on;lr;did=67a.f1e1^M Record-Route: sip:192.168.0.206;r2=on;lr;did=67a.f1e1^M Via: SIP/2.0/UDP 10.197.184.1;branch=z9hG4bK3fe4.fc634d55237786cb052f1c0d4fd7d949.0^M Via: SIP/2.0/UDP 192.168.6.108:5260;received=192.168.6.108;TH=div;rport=5260;branch=z9hG4bK2821386093^M ``` Is it correct behavior?
