[Serusers] Users in ENUM
by Anderson Alves Albuquerque 21 Feb '06

21 Feb '06

If I have a prefix 1100 and I send call to 11000202, how can I use ENUM this? If I have the line below, I would need to put username but I don´t want this: $ORIGIN 0.2.0.0.0.1.1.e164.arpa. 2 IN NAPTR 1 10 "u" "E2u+sip" "!^.*$!sip:10.10.10.1<r(a)10.10.10.1>; sip:john@10.10.10.2!" . Suppose, I send to 11000202 or 11000203 I want send call to 10.10.10.2 but I want to use the e164 original. If have a lot of users I would need to put all the users in ENUM, but I don´t want this. How can I do this?

[Serusers] Forwarding to port 5060 when UA behind NAT
by Arek Bekiersz 21 Feb '06

21 Feb '06

Dear list, I have situation where SIP UA is behind NAT, that maps everything to ports above number 61000. I use nathelper, rtpproxy and SER 0.8.12. Everything works fine. Until I have UA that does not send "Contact" field in BYE (or OK for BYE) during call termination. In this case SER is forwarding responses not to NAT-ed port, but to port 5060. QUESTION: What can be done to correct this situation? Is this improved in new SER releases? Sequence is as follows: IP_of_A:61001 -> IP_of_proxy:5060 BYE sip:B@IP_of_proxy loose_route ... IP_of_proxy:5060 -> IP_of_B:5060 BYE sip:B@IP_of_B ... IP_of_B:5060 -> IP_of_proxy:5060 SIP/2.0 200 OK ... IP_of_proxy:5060 -> IP_of_A:5060 <WRONG! Should be 61001> SIP/2.0 200 OK ... It does not happen when terminating UA sends "Contact" field in first BYE. -- Regards, Arek Bekiersz

[Users] TLS stability
by Klaus Darilion 21 Feb '06

21 Feb '06

Hi! Recently on the serdev mailinglists there were considerations about the stability of the TLS code: http://mail.iptel.org/pipermail/serdev/2006-January/006608.html I know there was a fix to disable openssl compression. Was this the only known problem? Is TLS now running stable? Has someone ever used the TLS stack successfully under load? regards klaus

[Users] preparation of patch release 1.0.1
by Daniel-Constantin Mierla 21 Feb '06

21 Feb '06

Hello everybody, a new package building of CVS branch rel_1_0_0 (release v1.0.0) will take place soon. This comes as an update to release 1.0.0 which will include the fixings occurred since 1.0.0 was released. We like to collect all issues of v1.0.0 you are aware of, to be fixed before package generation. Next is a list of the issues that should be fixed: - TLS - when TLS connections is refused, immediate reply instead of waiting for timeout - TCP - when the call is initiated over TCP but the contact advertised is UDP, the BYE from callee is not routed properly (it is tried TCP due to double RR) - record_route_preset() parameter size - ruri matching of canceled transactions (see: http://openser.org/pipermail/users/2006-February/002951.html) Any feedback is appreciated. Cheers, Daniel

[Users] add/rewrite a tag/parameter in SDP
by Lenir 21 Feb '06

21 Feb '06

Hey guys, What is the best way to modify the SDP message to always include (if not replace) the a= tags in a SDP message? My problem is specifically with g729, according to the RFC, if the parameter: "a=fmtp:18 annexb=yes" is present or missing then it is assumed that g729b (g729 with VAD) and if "a=fmtp:18 annexb=no" is present then the devices will use g729a (g729 with VAD Disabled). My problem is that some cisco gateways and ATAs behave differently (of course Cisco always doing it their way), if "a=fmtp:18 annexb=no" is missing then it assumes that g729a will be used, instead of following the RFC where it should negotiate g729b. Also, asterisk doesn't support g729b so I want to avoid using g729b everywhere in my network. So what is the best way or is there a way, to either: a) insert "a=fmtp:18 annexb=no" if is not present b) replace "a=fmtp:18 annexb=yes" for "a=fmtp:18 annexb=no" if it is present Thanks in advance!! Lenir p.s. Please see the below excerpt from RFC 3555 regarding how to specify G729. RFC 3555 MIME Type Registration of RTP Payload Formats July 2003 4.1.9. Registration of MIME media type audio/G729 MIME media type name: audio MIME subtype name: G729 Required parameters: None Optional parameters: ptime, maxptime annexb: indicates that Annex B, voice activity detection, is used or preferred. Permissible values are "yes" and "no" (without the quotes); "yes" is implied if this parameter is omitted
