[Freeswitch-users] double invite

[budi wibowo]

dear all
i use FreeSWITCH Version 1.0.head (git-9d3401e 2012-03-19 20-06-36 -0500)
and connect to some gateway over sip.
during test i found
- 2 Invite from FS then receive 1 Trying from other gw
- FS send cancel and other gw return 481
- FS send ACK , and got return BYE
is it common happen? or any config in FS i can use to fine tune the setting?
attached is detail pcap file for consideration

TIA
