Using the term 'fragment' here is confusing. There are two perfectly legal ways to add Vias: as one long Via header with many values, or as a series of Via headers. Different products do it differently, both are fine and even mixtures of the two should work. Choosing to use multiple Via headers is not 'fragmenting' the header - it's just a different expression of the same value that some (including me) find easier to read than a single long line (it adds 4 or 5 bytes per value to do it that way). There are a fair number of products out there that cannot handle UDP datagrams that are fragmented at the IP level into multiple packets, which happens with large SIP messages. The largish Via headers (and longer Route/Record-Route headers) from sipXproxy sometimes trigger this problem, but I'm guessing that in your case it's just the '%' character. > On a different note, you mentioned above that out of the 3 via headers > one can be eliminated by having DNS SRV records.
