Not necessarily... I have a similar problem where my provider won't accept fragmented UDP packets, nor will they accept SIP over TCP. IMO this is a shortcoming of sipx that should be addressed. A single SIP Proxy should only require a single via header. Sipx is very liberal with the packet size consider there isn't much room to work with before the packet becomes fragmented. My temporary work around for this is to use a stripped down asterisk box for forwarding calls only. It re-originates the call and therefore eliminates all previous via headers from it's point out. I recommend using the "canreinvite" features of the SIP trunks in asterisk to allow direct media.

There is nothing unusual about an INVITE having four Via headers. If the UA ignores INVITEs that have four Via headers, it is *severely* broken. > The proxy is sending invite also via TCP and after 4 or 5 retries, > playing some greeting to the caller saying destination is unavailable > and asking to record the message even if destination is actually > available. It looks like the phones aren't successfully registering. Do they show in the Registrations screen of sipXconfig?
