Hi Daniel! I've tried Yealink and Cisco SPA-303 They send very similar ACKs, the problem seems to be not in their SIP stacks. Original ACK URI is correct uri from 200 OK contact. Route: header is set to correct value from Record-Route from 200 OK. Maybe my NAT handling code makes something wrong with original ACK...
There is kinda unusual IP setup on machine - there is quagga daemon, there are many public IPs and one of machine's public IP addresses is set as /32 on loopback to be announced with BGP. But routing is correct, so I don't think there are issues with this. mhomed = 1 in kamailo config. I'll get full SIP dumps and post it there. Thanks! 2015-04-17 12:32 GMT+03:00 Daniel Grotti <dgro...@sipwise.com>: > Hi, > please also check if you have set aliases (kamailio.cfg global > parameters) to the IP address in the R-URI. > > > -- > Daniel Grotti > VoIP Engineer > > > Sipwise GmbH > Europaring F15 | 2345 Brunn am Gebirge, Austria | www.sipwise.com > > On 04/16/2015 07:23 PM, Dmitry Sytchev wrote: >> Hi all! >> >> I can't make my Kamailio to correctly relay stateful ACKs for 200 >> OK.
