*13.4-SIP- no early media even after 183 Session Progress


#1

Hello,

RTP does not flows-out after I get Progress on the channel, but as soon as the channel is answered RTP starts flowing-out.

I have “Asterisk 13.4.0” and I am trying to playback a prompt without answering the call, but unable to achieve that.

[default]
exten => 99966,1,Goto(noanswer_demo,s,1)

[noanswer_demo]
exten => s,1,Progress()
exten => s,n,Monitor(wav,testCall-${STRFTIME(${EPOCH},GMT+3,%C%y%m%d%H%M)})
exten => s,n,Background(hello-world, n) ; ----> 1
exten => s,n,WaitExten(1)
exten => s,n(cont),Playback(hello-world, noanswer) ; ----> 2
exten => s,n,Wait(1)
exten => s,n,Playback(hello-world) ; ----> 3
exten => s,n,Playback(demo-instruct)
exten => s,n,Playback(hello-world)
exten => s,n,Playback(demo-instruct)
exten => s,n,Hangup()

NOTE: the recorded file (testCall-201508241206.wav in this case) has all the prompts in it (starting from 1,2,3 …)
BUT called-party only hears from 3 onward, after call get answered.

here are the logs of verbose, SIP debug and RTP debug

i am getting following as the Media Direction instead of standard “sendrecv, sendonly, recvonly …”

can this be the cause of Media not flowing out of my node.


#4

tested the same issue with following * versions BUT same result
[ul]- Asterisk-1.8.23.0

  • Asterisk-11.3.0
  • Asterisk-11.4.0[/ul]

any help will be highly appreciated


#5

a is not media direction. It is a general attribute field.

Please re-edit so that the log is in a code block; that results in a lot less scrolling.

I wonder if this relates to the probation message, i.e. it won’t send media unless it has received it. I don’t really get involved with NAT, but I think there are NAT hacking options (nat=) that use the de facto remote media address and ignore the SDP.

Also please note that the only suitable questions for the General forums are rhetorical ones; if you want support use the Support forums.


#6

edited the posts as guided, thank you for the education :smile: … appreciated (Y)

re-posting in support forum


#7

I have finally solved this issue :smiley:

thanks to the post No RingBack Tone by MasterLog

progressinband=yes
internal_timing=yes
silencesuppression=no

and my Dial command :: Dial(“SIP/@,45”)

this passes any indication (received from B-Party) to A-Party.

Thank you david55 for the help.

by the way, now I am working with Asterisk 11.3.0, modified to support SIP-I.
will try to patch 13.4.0 to support SIP-I (if I get time).

How can I mark this as solved ??

Hello Usmanbaiga,

We are setting up a connection between a Nokia switch and an Asterisk wich is intended to work as a validation IVR for long distance calls.

Since Nokia supports only SIP-I, there is an SBC in between for interworking between SIP and SIP-I, Our Asterisk is not set for SIP-I.

The Nokia sends a SIP-I Invite to the SBC, with p-early-media header. SBC forwards this message to the Asterisk with plain SIP but keeping the p-early-media header (RFC 5009).

Asterisk is expected to respond back with a Session Progress 183 message including the p-early-media header (and value sendrecv or similar), but such a message is never added to the Session Progress (Asterisk does not seem to support such a header).

Result is that audio does not go through due to the lack of p-early-media response back to Nokia switch. This means that Calling Party does not receive the audio sent by Asterisk after the 183 message. We need to send such pre call annoucement to before call is answered by called party.

Questions:

  1. Based on some traces I saw from you, it looks like your Session Progress messages were also lacking the p-early-media.

  2. It is not clear from the traces wether your setup was handling the SIP-I since all responses to the Invite do not include any ISUP message (I would expect i.e. ACM message embedded on Session Progress, but I am not handred percent sure of this).

  3. The ACME SBC that sits in between was configured to add the p-eary-media to the 183 Session Progress message. Still Nokia does not open the audio path. So, probably, even if Asterisk would be able to respond with p-early-media, it will probably not work, Based on some previous expiriences we might have to talk directly to Nokia through SIP-I. So I wanted to ask you if you mind verifying whether your final configuration with SIP-I is able to add p-early-media on 183 Session Progress message (I do not see it on the traces you shared but I am not sure if those were the last ones).

Thanks in advance!

Martin

  1. Asterisk is NOT suppose to send “Session Progress 183” unless you instruct it to do so (using the Progress() application)
  2. as suggested above, please use the Progress() application in your Dialplan

If things still dont work, please take a trace and share it.

NOTE: FYI, I was able to patch asterisk 13 to support SIP-I and I had tested it with Nokia and Huawei MSS successfully.


#10

Thanks for your response.

We do send Session Progress 183 with Asterisk. That is not the problem, as you can see on trace below.

Problem is that “Session Progress 183” does not include the p-early-media header.

So, first of all we would like to find a way to add the p-early-media on the 183 message, over plain SIP, and check if we are able to get audio going through.

Still, we believe this is not going to solve our isue (open media both ways).

Second step for us would be moving to SIP-I. We downloaded Asterisk-i but did not start yet. Any help from your side for SIP-I over Asterisk 13 would be much appreciated.

It is great news you succeded testing it with Nokia MSS. I wonder in such a case, whether your 183 Session Progress includes or not p-ealy-media.

In case of Huawei we are talking to it plain SIP and it works ok. It does not require p-early-media. 183 message is enough to open the media.

Thanks for your help!

Regards,
Martin

#11

Let me correct my self,
I was successfully able to patch asterisk 11.3 for SIP-I

the traces (from my setup) doesnot shows p-early-media header in “Session Progress”.
this doesnot seems to be the issue.

please try these settings
.

If not successful, please share asterisk CLI logs after turning-on with following
*CLI> sip set debug on
*CLI> rtp set debug on
*CLI> core set verbose 10
*CLI> core set debug 10
