Re: Re: Re: Re: [Serusers] call forwarding issue - attr_destination() error: Feb 12 14:37:53 rd ser[3979]: parse_nameaddr(): No < found - ottendorf

Yes but this ruri sip:hellboy@192.168.0.116:5060 is set after the invocation of lookup_contacts(). the function is invoked on the message which contains ruri changed by the forward_blind parameter. There is first "round" when processing of the first INVITE reaches the checking of the forward_blind parameter after which I invoke the attr2uri and just after this make the t_relay. then there is second "round" with the changed ruri. before lookup_contacts I see the ruri as mm(a)voip.touk.pl and after sip:hellboy@192.168.0.116:5060 which is in fact the location corresponding to sip:hellboy@voip.touk.pl. there is no message sending through the network but the message with the new ruri is processed which is visible in the log file I see it logged with the changed ruri?? So where is the problem?? Is it the problem of attr2uri? I tried it by using rewriteuri() and it gave me the same result. changed ruri but lookup_contacts() returns value corresponding to the first ruri. Maybe lookup_contacts() checks not the ruri?? > Yes, your request-uri is sip:hellboy@192.168.0.116:5060 which I think > will not be looked up in location (lookup_contact should fail), so it > does not rewrite the request-uri at all. > > Michal > > On Mon, 2007-02-12 at 16:05 +0100, tzieleniewski wrote: > > hmm > > it is strange because I can see that after attr2uri and t_relay() message again enters the main route block and goes through the whole processing but I can't see the message being send through the network. the recourd_route and via headers are being attached which is visible in the message send to unwanted (contained in the first invite - in this case myself because I try this by calling my self and setting forward_blind to another sip uri) destination: > > > > U 2007/02/12 16:05:12.199566 192.168.0.74:5060 -> 192.168.0.116:5060 > > INVITE sip:hellboy@192.168.0.116:5060 SIP/2.0. > > Record-Route: <sip:192.168.0.74;ftag=218741881;lr=on>. > > Record-Route: <sip:192.168.0.74;ftag=218741881;lr=on>. > > Via: SIP/2.0/UDP 192.168.0.74;branch=z9hG4bK5141.91077cd7.0. > > Via: SIP/2.0/UDP 192.168.0.74;branch=z9hG4bK5141.81077cd7.0. > > Via: SIP/2.0/UDP 192.168.0.116:5060;rport=5060;branch=z9hG4bK0FCAE301A64EA5A82F9E7BE990AD76FB. > > From: hellboy <sip:hellboy@voip.touk.pl>;tag=218741881. > > To: <sip:hellboy@voip.touk.pl>. > > Contact: <sip:hellboy@192.168.0.116:5060>. > > Call-ID: 4C739990-7D22-D9F2-72CE-D5F10A9BC99F(a)192.168.0.116. > > CSeq: 54988 INVITE. > > Proxy-Authorization: Digest username="hellboy",realm="voip.touk.pl",nonce="45d08354b71cd0fddc45daa67447c271fd6b36db",response="054c2a5a43cb527ea70a8040dde9aaa0",uri="sip:hellboy@voip.touk.pl",qop=auth,cnonce="29546711E944E708A52A2122A1E71614",nc=00000001. > > Max-Forwards: 15. > > Content-Type: application/sdp. > > User-Agent: X-Lite release 1105d. > > Content-Length: 240. > > P-hint: usrloc applied. > > > > I put the whole ngrep output in the attached file > > > > Tomasz > > > Seems very strange to me, that incoming message would remember the > > > request uri as it was before rewrite.... do you really forward it? > > > > > > Please attach network capture. > > > > > > Michal > > > > > > On Mon, 2007-02-12 at 15:23 +0100, tzieleniewski wrote: > > > > Thanks it worked but another thing appeared:) > > > > > > > > Everything works fine, I see the message being routed again to ser with > > > > different ruri but at the end of the message processing when I invoke the > > > > lookup_contacts("location") function the message is forwarded to the location which > > > > corresponds to the first ruri which was changed by attr2uri() function. > > > > Please point me what do I miss. > > > > > > > > Generally my procedure looks like this: > > > > > > > > if inbound user then > > > > check if user have forward_blind parameter > > > > if yes > > > > rewrite ruri (attr2uri("$tr.forward_blind")) and forward with > > > > t_relay() > > > > > > > > So for instance when I call myself and have the forward_blind set on the account on which user is not registered I get the 486 - busy response instead of the unavailable user. > > > > > > > > > > > > > On Mon, 2007-02-12 at 14:32 +0100, tzieleniewski wrote: > > > > > > Hi again > > > > > > I found out that there appears the following error in the log: > > > > > > Feb 12 14:37:53 rd ser[3979]: parse_nameaddr(): No < found > > > > > > > > > > The attr_destination uses the same uri parser as core, and is able to > > > > > accept event the nameaddr specification... so if you put uri without <> > > > > > you will get this "warning". > > > > > > > > > > It just rewrites internal next hop, so the t_relay will send it as > > > > > appropriate.
