i am trying to follow this http://www.iptel.org/ser/doc/ser_radius/ser_radius.html and using radiusclient-0.3.3.tar.gz on one mechine and freeradius on another but i am unable to fix it radclient is not installed there is radiusclient so i cannot use this root@/usr/local/src# radclient -f digest localhost auth <shared_secret> this thing is working properly on my other mechine but this time radclient is not available any link thanks kamran __________________________________ Do you Yahoo!?

[Serusers] ser not sending ACK back to MGW

by Colin Dalton

Hello, Apologies if this has come up before, but I'm having some problems with SER not forwarding an ACK back to a Cisco AS5300 media gateway. This means that incoming calls break down because the 5300 hasn't received an ACK from the SIP phone. Outgoing calls are fine, because SER is forwarding the 5300's ACK back to the SIP phone correctly. Would anyone know why this is only working in one direction? With incoming calls, the sequence of events is: 1. I dial the PSTN number on my SIP phone. 2. The SIP phone sends the INVITE to SER. 3. SER rewrites the host and forwards it to the Media Gateway (MGW) 4. The MGW brings up an ISDN channel and connects the call 5. When the call is answered, the MGW sends back the 200/OK to SER 6. SER forwards the 200/OK on to the SIP phone and I can converse on the call 7. The SIP phone sends the ACK back to SER, but SER doesn't send it on to the MGW. 8. The MGW waits 19 secs before disconnecting the call because it hasn't received an ACK. In the reverse direction everything works fine, because SER sends on the ACK it receives from the AS5300. My configuration is appended below. Running IOS 12.3(9) on the 5300, the SIP phone is a Siemens Optipoint 400. SER version is 0.8.10 on Fedora Core 3.

The meaning of the return value of loose_route is as follows (or should be): 1 - Record routing was used to route the message 0 - Record routing was not (usually requests establishing a dialog or transactional requests). So the function should return true in the mentioned case, because record routing was used although the message does not contain any Route header fields anymore. In other words the purpose of loose_route return value is to distinguish mid-dialog requests (such as ACK or BYE) from dialog-establishing requests (such as INVITE). The reason why we have to do this is that we typically do not apply all the logic in the script to mid-dialog requests (because you should not change the request-uri of the request anymore once the dialog has been established -- changes caused by loose_route do not count). You may also wonder why don't we use the contents of the Request-URI for this -- there should be the Contact value of phone1 in the Request-URI in mid-dialog requests and the value should not match uri==myself so all we need to do is to enclose all the processing logic within if (uri == myself) condition. This would work in a perfect world without the need to be backwards compatible with strict routers. In our world we have to be backwards compatible with strict routers and we have to deal with broken implementations too (that strip ;lr parameters). Due to backwards compatibility with strict routers it can happen that the Request-URI will contain the URI of the proxy that is currently processing the request and subsequent if (uri==myself) would be true.

[Serusers] invite + options

by João Salgueiro

Hi! i need access to the callee sdp before the connection is established, so i guess i need to do the following: UAa -> sends INVITE SER -> holds the INVITE and sends an OPTIONS to UAb UAb -> responds to OPTIONS SER sends INVITE to UAb is this possible? i need access to the callee sdp before the connection is established. thanks in advance, Joao Salgueiro

[Serusers] SER Newbie

by Daniel Eboa

Hello list, I'm new in SER, and i have problem setting up the application. I have asterisk pbx using SIP and a billing application for voip using radius authentication. The billing use MSSQL database and the Radius server is under Linux. I installed radiusclient on the same machine with ser-0.8.11-0.rpm. The problem is that when I do: ser start, I have this: 127.0.0.1 [127.0.0.1]:5060 XXX.XXX.XXX.XX [XXX.XXX.XXX.XX]:5060 Aliases: host-XXX-XXX-XXX-XX.interpacket.net:5060 localhost:5060 localhost.localdomain:5060 SER:5060 XX is the IP of the SER machine. But when I do "serctl monitor", I got this: [cycle #: 1; if constant make sure server lives and fifo is on] And nothing happen. This tells me that ser is not running. Can somebody help me with my setup. Thanks. Daniel

Re: [Serusers] No sound with ser 0.9.0 and mediaproxy 1.2.1

If you had it working with mediaproxy 1.3.1, try upgrading it again. Also, there is a debug option for mediaproxy so you can see what happens, but I don't recall what it is now. g-) Roger Lewau wrote: > Hello Greger, > > Thanks for your ideas, however all SIP messages are ok, including SDP > line as you mentioned.
