Hello Daniel, 
I want do clean up on routes from first SUBSCRIBE, that when traffic goes to public side of kamailio will be only public route and when traffic is internal the Record-Route will stay internal only. In SDP I see like this. 
I tired double routes set 0 in rr, but didn't clean enough.

Hello, 

can you give an example of incoming header and how you want to be after modification? 

It is not clear for me what end result you want/expect. 

Cheers, 
Daniel

Hello Everyone, 
Here updated version. Trying remove Record-Route after the coma. 
My log shows 

Mar 14 01:25:21 canlvprx01 /usr/sbin/kamailio[751]: INFO: <script>: [SUBSCRIBE], Inbound connection from <Client Public IP> 
Mar 14 01:25:21 canlvprx01 /usr/sbin/kamailio[751]: ERROR: <script>: <null> 
Mar 14 01:25:21 canlvprx01 /usr/sbin/kamailio[751]: INFO: <script>: [SUBSCRIBE], Route for removal: '<null>' 

route snippet. 

route[ROUTE_HDR_ORG] { 
# Getting record routes 
if(is_present_hf("Route")) { 
xlog("L_INFO", "[$rm], Inbound connection from <$si>\n"); 
if(is_method("SUBSCRIBE")) { 
if(is_ip_rfc1918($si)) { 
xlog( "$sel(@hf_value.Record_Route[-1])" ); 
xlog("L_INFO", "[$rm], Route for removal: '$sel(@hf_value.Record_Route[-1])'\n"); 
remove_hf_value("Record-Route[-1]"); 
} else { 
xlog( "$sel(@hf_value.Record_Route[1])" ); 
xlog("L_INFO", "[$rm], Route for removal: '$sel(@hf_value.Record_Route[1])'\n"); 
remove_hf_value("Record-Route[1]"); 
} 
} 
} 
return; 
}

Hello Everyone, 
I am trying adjust Record-Route, but can't match headers value 

And I am call route(ROUTE_HDR_ORG); right after route(WITHINDLG); 

route[ROUTE_HDR_ORG] { 
# Getting record routes 
if(is_present_hf("Record-Route")) { 
if(is_method("SUBSCRIBE")) { 
xlog( "$sel(@hf_value.Record_Route[1])" ); 
xlog("L_INFO", "[$rm], Route for removal: '$sel(@hf_value.Record_Route[1])'\n"); 
remove_hf_value("Record-Route[1]"); 
} 
} 
return; 
} 

Any help Thank you, 
Slava.
