Re: [sr-dev] Via parser does not accept any token as transport

you started the discussion when many of us were partying for 10 years celebration :-) so it got lost -- reminders are recommended always. There is no real good reason why not accepting unknown transport protocols non-top Vias. The limitation is coming from implementation of the parser, but should be relaxed. The best would be to introduce PROTO_OTHER in the enum of protocols (ip_addr.h, enum sip_protos) and in case this type is encountered, read the string value of the protocol. Via parser is using quite a lot of states, so if you look to update it, when it gets to the state where the transport (proto) part starts, if does not match UDP, TCP, TLS or SCTP, then set vb->proto=PROTO_OTHER and start and length of the token in vb->transport. Should not be very complex to enhance once you get into via parser states. I may fix it before 3.2.0 is out if you are not doing it meanwhile, but cannot give you a timeline for it right now.
