RE: Re[2]: [Serusers] NAT vs. NoNat authentication
by Bart Van Daal 19 Jul '04

19 Jul '04

Hi Mike, thanks for the answer and the tip.. I can see the sipserver sending multiple '401' to the router, so I guess the router just drops these packets because it doesn't know what to do with them? I now have put the UA in dmz but that still doesn't solve the problem. I'll look further. > -----Original Message----- > From: Mike Tkachuk [mailto:mike@yes.net.ua] > Sent: maandag 19 juli 2004 11:56 > To: Bart Van Daal > Subject: Re[2]: [Serusers] NAT vs. NoNat authentication > > > > Hello Bart, > > Looks like UA not receiving 401 unauthorized message from > SER, that's why it not resend REGISTER message with calculated digest. > Maybe you have some troubles with NAT on 213.219.137.148? > > Hint: use ngrep with -W byline option (eg: ngrep -W byline port 5060 ) > > -- > Best regards, > > ~*-,._.,-*~'`^`'~*-,._.,-*~'`^`'~*-,. > Mike Tkachuk, ph:380-3433-47067 > YES ISP, fx:380-3433-47067 > Valova 17, mike|a|yes.net.ua > Kolomyia, www.yes.net.ua > Ukraine 78200 FWD: 66518 > > 19.07.2004 > ICQ# 57698805 > MSN: mike_tkachuk|a|hotmail.com > ~*-,._.,-*~'`^`'~*-,._.,-*~'`^`'~*-,. >

[Serusers] Spontaneous UDP Port Change on SMC Router
by Andres 19 Jul '04

19 Jul '04

Hi, This is a new one for us. We were getting complaints of dropped calls from one of our subscribers. We analyzed sample calls and it turns our his SMC Router is spontaneously changing the source UDP port of the media stream in the middle of the call! Has anybody else seen this strange behaviour on any router? The problem also affects SIP registrations. Even with a Keep Alive of 3 seconds in the Sipura settings, the SMC spontaneously changes ports every 5-6 minutes. -- Andres Network Admin http://www.telesip.net

Jan,Do you have any idea of how much the license would be? Could we have a model where is it licensed per channel? I think asterisk uses this model. We would be willing to fund development.

[Serusers] NAT contat rewrite
by Linus Surguy 18 Jul '04

18 Jul '04

Hi all, I'm sure I must be doing something very stupid! I'm using fix_nated_contact and then t_relay(). The INVITE is being sent with a rewriten contact field, but if the UA issues a CANCEL the private IP address is sent in the contact field and is not rewritten. What basic mistake have I made?! A cut down version of my ser.cfg is: record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; fix_nated_contact(); force_rport(); if (method=="INVITE") { fix_nated_sdp("1"); force_rtp_proxy(); /* set up reply processing */ t_on_reply("1"); setflag(6); }; rewritehostport("213.xxx.xxx.xxx:5060"); if (!t_relay()) { sl_reply_error(); }; # all incoming replies for t_onrepli-ed transactions enter here onreply_route[1] { fix_nated_contact(); if (status=~"[12][0-9][0-9]") force_rtp_proxy(); }

[Serusers] How to log variables?
by Dave 18 Jul '04

18 Jul '04

Hi, I would like to do some comprehensive logging and/or write routing scripts based on variables. How do I log the parts of the SIP message to a logfile ? For example how do I log the To/From or UAC Ip address? Is there a summary of the msg:xxxx variables somewhere (i.e. I know about the msg:len but others?) Thank you, Dave.
