Hi, very grateful if some one can shed hints into my scenario. I am running
SIPp svn 590.

My UAC is talking to UAS through a SIP Register/Proxy. When UAS received the
INVITE from SIP Proxy, the via headers were listed as followings:

        Via: SIP/2.0/UDP
192.168.2.6;branch=z9hG4bK-sipapp-08cfafff1cf32f14e2fbdfd1262508a85dce
        Via: SIP/2.0/UDP
192.168.2.6;branch=z9hG4bK-sipapp-08cc700bca9b03bc99aafb4ffc9432f4f085~6b297
230d8cf380f65237fe376032c4e
        Via: SIP/2.0/UDP 192.168.2.2:47911;branch=z9hG4bK-23688-1-16

When UAS responsed with 180 ring by [last_Via:], the via header was listed
as following:
 
        [truncated] Via: SIP/2.0/UDP
192.168.2.6;branch=z9hG4bK-sipapp-08cfafff1cf32f14e2fbdfd1262508a85dce,
SIP/2.0/UDP
192.168.2.6;branch=z9hG4bK-sipapp-08cc700bca9b03bc99aafb4ffc9432f4f085~6b297
230d8cf380f65237fe376032c4e, SIP/2.0/UDP 192.168

Is it normal or not for the truncated via header ?
 
While it was strange that my SIP Register/Proxy sent UAS another unexpected
INVITE and that struck my scenario.
 
Regards,
