[Asterisk-Dev] Got SIP response 481 "Invalid CSeq Number" back from

[Federico Alves]

I keep getting this problem every 5 calls from a Cisco AS5300. I use
G711-ulaw, with the default 160 bytes per frame (that is what the cisco
debug shows). I use no dtmf-relay. My dialpeer looks like this:

dial-peer voice 4481 voip
 huntstop
 incoming called-number 448.T
 voice-class h323 1
 voice-class sip url sip
 session transport udp
 codec g711ulaw bytes 160
 no vad
!    

The question is: is this a symptom that the SIP channel is broken in HEAD? I
use the latest HEAD version from 4 days ago. Can somebody please help me
understand the issue?
