[Users] Two c= tag in sdp body
by Pletli Antal 03 Aug '06

03 Aug '06

Hello, I use OpenSer with Cisco AS5300/5350/5400 with IOS 12.3. When Cisco sends an OK 200 SIP message to OpenSer, there are two "c=IN IPV4" tags in sdp body with the same IP address. The nathelper module only replaces the last occurence of c= tag so some SIP clients works wrong because those get the first IP from the first "c=" tag... How can i replace the all occurences of "c=" tag in sdp body with the help of nathelper? Thx, Antal Content-Type: application/sdp. Content-Length: 277. . v=0. o=CiscoSystemsSIP-GW-UserAgent 7144 773 IN IP4 213.253.220.242. s=SIP Call. c=IN IP4 213.253.xxx.xxx. -> this is the original address of Cisco GW t=0 0. m=audio 35944 RTP/AVP 18. c=IN IP4 213.253.xxx.yyy. -> this is the nated address replaced by nathelper a=rtpmap:18 G729/8000. a=fmtp:18 annexb=no. m=video 35946 RTP/AVP. c=IN IP4 213.253.220.253. a=nortpproxy:yes.

[Serusers] t_relay
by Victor Pascual Ávila 03 Aug '06

03 Aug '06

hi all, can a t_relay that got no answer be forwarded to a voicemail? The scenario is the following: i have a 'call group' sip-user (implemented in mysql database) that call t_relay when an INVITE is rcvd. As consequence of the t_relay the mentioned INVITE is forwarded to different destinations, and when one destination answers the call a CANCEL is sent to other destinations. The problem exists if no destination attends the call. How can I tell ser to forward the call to voicemail if no user belonging to group 'call group' answers the call? thanks!!! victor -- Victor Pascual Ávila mail: victor.pascual.avila(a)gmail.com sip: 17476374121(a)proxy01.sipphone.com linux user: 224443

[Users] Troubles with avp and fr_inv_timer_avp
by Michel Zenone 03 Aug '06

03 Aug '06

Hi! Does somebody know why 'fr_inv_timer_avp' does nothing when I use it as follow: ... modparam("tm", "fr_inv_timer_avp", "inv_timeout") ... modparam("avpops","avp_table","avptimer") # 'avptimer' is like 'usr_preferences' ... avp_db_load("$ruri/username","i:inv_timeout/avptimer"); avp_write("i:inv_timeout","inv_timeout"); # In avptimer there is an attribute 'inv_timeout' Actually I try to set a fr_inv_timer different from an user to another. 'avptimer' timer defines, for each users, their proper fr_inv_timer. If somebody can help... Thanks in advance, Michel

This is so that the machine can act as RTP proxy on network edges. Since your SIP message has no SDP body there is nothing nathelper can do :-) C'ya, Marc -- Marc Haisenko Comdasys AG Rüdesheimer Straße 7 D-80686 München Tel: +49 (0)89 - 548 43 33 0 Fax: +49 (0)89 - 548 43 33 29 e-mail: haisenko(a)comdasys.com http://www.comdasys.com

[Serusers] 404 not found for SUBSCRIBE
by amit.malagi＠wipro.com 03 Aug '06

03 Aug '06

Hello all We have just installed SER_0.9.6_linux_i386 without MySQL support. We have registered two users with SER using jain-sip-applet-phone. We can make calls between them successfully. But, when we try to make one user a contact of the other, SER sends a "404 not found" for the SUBSCRIBE message. Appreciate any help in resolving this issue. Thanks and regards Amit.

Anyone knows why I keep getting following error message? Aug 2 13:10:26 localhost openser[30695]: ERROR: extract_body: message body has length zero Aug 2 13:10:26 localhost openser[30695]: ERROR: force_rtp_proxy2: can't extract body from the message I turn on nathelper, and saw from the following source code: int extract_body(struct sip_msg *msg, str *body ) { body->s = get_body(msg); if (body->s==0) { LOG(L_ERR, "ERROR: extract_body: failed to get the message body\n"); goto error; } body->len = msg->len -(int)(body->s-msg->buf); if (body->len==0) { LOG(L_ERR, "ERROR: extract_body: message body has length zero\n"); goto error; } Why do we care about the content-length, which normally is 0 for most of the SIP UAs?
