Send rtp directly between bridged calls!

tareqmy · January 13, 2009, 7:13am

Hi,

my dialplan has this context -

[ctx]
exten => _XXXXXXXXXX,1,Dial(SIP/x@y.com)

So that calls to the ‘ctx’ it is bridged to ‘x@y.com’.
My problem is i want the rtp to be sent directly between the ‘Caller’ and the ‘x@y.com’. Is that possible? If yes how to do it?

Thanx.

tareqmy · January 13, 2009, 1:09pm

i think i have the solution. canreinvite=yes in the sip.conf should solve the problem. http://www.voip-info.org/wiki-Asterisk+SIP+canreinvite

g2010 · January 13, 2009, 1:16pm

i believe there are two paramaters in sip.conf

canreinvite=yes
reinvite=yes

Just be aware that there are certain parameters to the Dial() application which will prevent a re-invite from happening.

As long as you are not behind any NAT and neither are the endpoints then setting canreinvite = yes and making sure TtWw or any other options are in the dial string and you are transcoding then yes it should reinvite

Ian

Note there isnt a reinvite = yes setting AFAIK its a redherring that has been doing the rounds for many years.

g2010 · January 13, 2009, 3:59pm

that would make sense… i never really understood the difference between reinvite and canreinvite!

ianplain · January 13, 2009, 4:50pm

The difference wa one worked the other didnt

Also by not defining canreinvite but setting reinvite to yes or no meant the canreinvite was set to yes as thats the default.

So in many cases it sort of seems it worked but in reality it didnt do a thing.

Have you tried directrtpsetup=yes in the [general] of sip.conf?

tareqmy · January 15, 2009, 9:24am

Thank you guyz for the responses. What is the difference between canreinvite and directrtpsetup?

I have a call between A and B, through Asterisk. I have used Dial application without the ‘t’ option, as it stops the canreinvite option. Now when i transfer the call using B to C. What should happen? What I am getting - call between A and C. But C cannot listen to A!!

Funny thing is If C is AutoAnswer enabled, they can hear each other!!!

What i need -
no rtp through asterisk and transfer capability.

Please help.

Thanx.

[quote]What i need -
no rtp through asterisk and transfer capability.[/quote]

In that case, you cannot use Asterisk feature codes for transfer, or any other mechanism requiring the detection of dialed of digits. You should still be able to use pure SIP transfers (the transfer feature built into the phone), and be able to use AMI to initiate transfers.

I’ve never explicitly used directrtpsetup. It might be defaulted in the sample configuration, though.

tareqmy · January 15, 2009, 11:13am

Hi, I actually didnt use Asterisk feature code for transfer. I used pure SIP transfer using my sip client eyebeam. Something I must be missing. Because both party can listen if the mentioned party C has Auto Answer enabled.

Also I was successful to transfer, using AMI action ‘Redirect’. Is there any other AMI action to transfer?

The main problem is what if previously mentioned party B uses the SIP way rather than relying on service provided me? So I actually need to enable asterisk for SIP transfer + canreinvite during a bridged call. Is that even possible?

tareqmy · January 18, 2009, 1:07pm

If anybody can help i am dumping debug log from asterisk for the case of AA(working) and NotAA(NotWorking)… this log is taken from the party B transfers till the party C answers.

It would help to have the differences highlighted.

In any case I find sip history (compact) or sip debug (complete) rather more useful than core debug.

Hi

A nice pcap file to stick in wireshark is nice and clean way of seeing whats happening. debug output get too confused.

I am sorry I had to paste such a long trace. but i am really lost here… can anybody help?

ianplain · January 21, 2009, 10:47am

Hi As mentioned earlier a pcap file fro wireshark will help.

I havent the time or inclination to read the trace in longhand, life is too short.

the command if you dont know it to get a pcap file of sip messaging is

tcpdump -n -i eth0 -w /tmp/wireshark.pcap -s 2000 udp port 5060

obviously if you are not using eth0 chang this to match you interface

if you want to include the rtp stream dont put the port 5060 bit at the end

Ian

tareqmy · January 21, 2009, 11:06am

yeah u r right about life being too short. infact i have the pcap capture of the SIP packets. but i could not find a way to attach them here…
so i am uploading the two traces here —

http://tareqmy.googlepages.com/AA.cap

http://tareqmy.googlepages.com/NotAA.cap

Thanx in advance.

i have gone through the sip and asterisk logs and source codes. i have found out following -

a call is established and rtp is going on between A(IP=X.X.X.X) & B(IP=Y.Y.Y.Y).
If a party sends a reinvite with destination IP=Z.Z.Z.Z, asterisk does not renegotiate it with the other party.
It renegotiates only in two conditions -
a. if the reinvite denotes IP=0.0.0.0 while active call
b. if the reinvite denotes IP=Z.Z.Z.Z while the call is held.

I was guessing, is that a bug? why does not asterisk renegotiate in the Step 2???

david55 · February 11, 2009, 4:13pm

Which version of Asterisk. It may well be a bug that was fixed years ago.

tareqmy · February 11, 2009, 4:18pm

really! is that solved!! i am using latest update of version 1.4. i wanted to use 1.6 but everyone said 1.4 is the most stable version… can you recommend what to use…

thanx.
