[Sip-implementors] AKAv1-MD5, calculating the response using RES

2016-04-06 Thread Polystar
Hi I'm trying to implement support for handling challenges with algorithm "AKAv1-MD5". Somehow I don't seem to get the correct calculated response, and at the same time RFC3310 seems pretty straightforward. AKAv1-MD5 consists of two steps, first calculate the RES using OperatorKey, SecretKey a

[Sip-implementors] Double checking the behavior of PRACK

2014-02-10 Thread Polystar
Hi RFC3262 says the following about UAC: "Note that the PRACK is like any other non-INVITE request within a dialog. In particular, a UAC SHOULD NOT retransmit the PRACK request when it receives a retransmission of the provisional response being acknowledged, although doing so does not c

[Sip-implementors] Mirroring record-route in 200 OK for NOTIFY?

2013-02-20 Thread Polystar
Hi If a UA subscribes to register events it will first send out an SUBSCRIBE request, receive a 200 OK for that request and eventually receive a NOTIFY. If that NOTIFY requests includes a Record-Route header, should that header be mirrored into the 200 OK for NOTIFY that the UE creates? RFC326

[Sip-implementors] SIP over TCP

2011-01-19 Thread Polystar T & M
Hi, I've just recently started to look at a scenario when SIP is sent over TCP (not UDP as I'm used to have). I see a behavior that I'm not really sure it correct: It's a very basic SIP call UAA -> UAB 1. UAA sends INVITE to UAB 2. UAB answers with 180 and 200 OK 3. UAA send

[Sip-implementors] Question on ABNF for P-Called-Party-Id header

2009-04-05 Thread Polystar T & M
Hi all, I have some problems matching an example of the P-Called-Party-Id header in rfc3455 with the ABNF for the same header (in the same spec) Section 5.1 in RFC3455 says the following: "5.2 P-Called-Party-ID header syntax The syntax of the P-Called-Party-ID header is described as follows:

Re: [Sip-implementors] RFC 3398 - ISUP/SIP mapping: 404 ->Unallocated number ??

2008-03-05 Thread Polystar T & M
Does "user not registered" really fit into the description of 404 in RFC3261? A subscriber that isnt registered does still exists in the domain that is handled by the server, doesnt it? I would say that the description of 480 is better for the unregistered case. RFC3261:
