[Serusers] is SER Dependable for prepaid System ? Anyone using it for prepaid system?

is SER Dependable for prepaid System ? Anyone using it for prepaid system? I very much like the SER performance in the test environment. Only drawback(maybe advantage if we provide unlimited plan) ) is stateless operation. But I want to know anyone using it in realtime prepaid business? Thanks, JiM

[Users] via header not added when transport=TCP?
by Erich Nahum 02 Aug '05

02 Aug '05

Howdy, I'm playing with OPENSER 0.9.5 with sipp as the workload generator on a bunch of linux boxes. When the transport is UDP, openser adds a via header like it is supposed to as a proxy. But when I use TCP no via header is added. This is a UAC->proxy->UAS scenario. Here's the header as seen at the UAS: | UDP message received [633] bytes : | | INVITE sip:service@10.0.1.41:5060 SIP/2.0 | Record-Route: <sip:10.0.1.42;ftag=1;lr=on> | Via: SIP/2.0/UDP 10.0.1.42;branch=z9hG4bKe9cc.cc24a79.0 | Via: SIP/2.0/UDP bronxville1:5060;received=10.0.1.40;branch=z9hG4bK-1-0 | From: sipp <sip:sipp@bronxville1:5060>;tag=1 | To: sut <sip:service@10.0.1.41:5060> | Call-ID: 1-31891@bronxville1 | CSeq: 1 INVITE | Contact: sip:sipp@bronxville1:5060 | Max-Forwards: 16 | Subject: Performance Test | Content-Type: application/sdp | Content-Length: 132 | P-hint: outbound And the corresponding message received at the UAS when using TCP: | TCP message received [495] bytes : | | INVITE sip:service@10.0.1.41:5060 SIP/2.0 | Via: SIP/2.0/TCP bronxville1:5060;branch=z9hG4bK-1-0 | From: sipp <sip:sipp@bronxville1:5060>;tag=1 | To: sut <sip:service@10.0.1.41:5060> | Call-ID: 1-31865@bronxville1 | CSeq: 1 INVITE | Contact: sip:sipp@bronxville1:5060 | Max-Forwards: 70 | Subject: Performance Test | Content-Type: application/sdp | Content-Length: 132 Note the absence of the 2nd Via header.

[Users] lcr from_gw in reply_route
by Klaus Darilion 02 Aug '05

02 Aug '05

Hi! Currently it is not possible to use the from_gw function in a reply_route. I'm no code expert, but to me it looks like it would be safe also to use it in a reply_route. Can please someone review this? regards, klaus

[Users] Problems with digest authentication
by aimable 02 Aug '05

02 Aug '05

I have been using various versions of SER from last year without any problem but recently I made a new installation of OpenSER 0.9.5. Since then I am having problems with digest authentication from some of the phones. I have a bunch of 186 ATAs and Cisco 7940 phones but they cannot register to the server, while all the soft phones can register successfully. The server says Credentials with given realm not found. I tried to change the realm to localhost and to the the IP address of the server, with no luck. And below is the result of ngrep I tried to grep the messages from the phones and here below is one message from a Cisco 186 ATA which has failed to register ########### Beginning of the capture ################## U PHONEIP:5060 -> SERVERIP:5060 REGISTER sip:SERVERIP SIP/2.0.

[Serusers] Xlite not working with SER+SEMS
by yu wang 02 Aug '05

02 Aug '05

Hi, I've been working on conference with Xlite but it is not work. The problem is SEMS starts sending media (default wav) back to Xlite once SEMS receives the INVITE/SDP from Xlite. It seems a bug on Xlite not listening on the media port after sending the INVITE thus it replys with ICMP port unreachable. But I don't see anyone complain this on this list. Is something wrong with my configuration? Please please help me.... Thanks, Pat

[Users] How to rewrite source IP -- SIP packet forwarding.
by Ray Van Dolson 02 Aug '05

02 Aug '05

I'm using nathelper with OpenSER 0.10.x. Here's a quickie diagram of my setup: [SIP ATA] <-------------> [OpenSER] <--------------> [Asterisk] 10.0.201.5 eth1 - 10.0.201.7 eth0 - <public_ip1> eth0 - <public_ip0> I'm using the basic nathelper example configuration, except for one modification. I removed the call to t_relay and replaced it with: t_relay_to_udp("<public_ip1>", "5060"); Basically I want a SIP packet to come in to eth1 on OpenSER server, get rewritten as needed by nathelper, then get sent out to public_ip1 on my Asterisk PBX. This appears to be working except a tcpdump on eth0 on OpenSER shows: 14:39:08.654908 IP 10.0.201.7.5060 > <public_ip1>.5060: UDP, length 629 Obviously the packets will never get back with that source IP address. What command should I be looking at to rewrite this IP so it shows up as <public_ip0> automatically? I'm trying to get SIP ATA's to REGISTER on my Asterisk box but proxy through OpenSER ... (and eventually make use of the rtp proxy). Can post more info if requested, I am new to SER. :-) -- Ray Van Dolson Linux/Unix Systems Administrator Digital Path, Inc.
