Hi, Hi, Thanks. Apart from re-entrance, I am also looking at a scenario of establishing two simultaneous connections with two different networks (a make before break). So I would need multi-threading support. best Vin ___ Sip-implementors mailing

Hi Marius, Thanks. I am not sure I quite understood what you mentioned in your previous mail. Do you mean use a customized stack at the transport layer in order to make multiple connections? In that case, I am afraid I do not understand why I need to tweak the layers above? The point is that

Another possibility is that dropping messages with long lines is an explicit policy of the ALG, rather than just being a crappy implementation. If so, then the responsibility lies with whoever set the policy. Thanks, Paul Paul Kyzivat wrote: Iñaki Baz Castillo wrote: Hi,

Hello, trying to clarify thoughts with early dialog forking, generally is there such concept? For instance when receiving two 180s with different tags, should: a) 2 early dialogs be constructed (why? is there any need to a REQUEST to be sent before receiving 2xx response which needs the tags?)

Hi Eduardo, Generally dialog is an end to end relation, not a SIP Proxy one. Proxy layer is built above transaction layer and there is no dialog forking there is only a request forking. When SIP Proxy receives a response, possibly related to forked requests, it finds the appropriate response

2010/9/2 Paul Kyzivat pkyzi...@cisco.com: (a) is the correct answer. You *may* need to send requests in an early dialog. For instance, a reliable provisional response requires a prack to be sent in the dialog. Also in some cases an UPDATE may need to be sent to carry an additional offer.
