IVR - Logs says playing but hearing silence


(Ponos) #1

Hello All,

I have a simple IVR configured to play an announcement then route to a ring group.

When I call the IVR I can see, from the logs, it’s playing the announcement however all I get is silence. I change to a system recording to rule out any format issues and I still hear silence. When I play the recording from System recordings I can hear the audio. For testing, I made the system recording ‘please-try-again’ the announcement on the IVR.

Appreciate any guidance.

Stephen

From the log:
– <SIP/User-1-000000e4> Playing ‘please-try-again.alaw’ (language ‘en’)

This sounds like a NAT issue. Is your FreePBX server behind a NAT device? Have you tried calling the IVR from an internal extension? You can use the feature code 7777 that simulates an inbound call.


(Ponos) #3

Thank you for the suggestion.

So if I call the IVR from internal I can hear the recordings – all good.

Checked the NAT settings and as far as my understanding goes are configured correctly.

I can make inbound/outbound calls to any extension which uses the same SIP provider as the IVR


#4

So sound works correctly for an inbound call from an external caller that goes directly to an extension without going through the IVR?


(Ponos) #5

Hi arielgrin, yes audio is perfect when I call an extension from external. Currently checking RTP port rage settings from the SIP provider.


#6

If audio works correctly and only the IVR is not working from external calls, the only thing I can think of is that the sound file is recorded in a format that can’t be transcoded. What codec are you using for your provider’s trunk and what codec is the audio file using?


(Ponos) #7

When I call the IVR from an internal extension the file is ulaw
When I call the IVR from external the greeting is alaw

My SIP settings include both ulaw and alaw

Calling IVR from an internal extension:

Executing [s@ivr-1:8] Set(“SIP/781-0000014b”, “IVR_MSG=custom/austin-greetng&custom/austin-greetng”) in new stack
– Executing [s@ivr-1:9] Set(“SIP/781-0000014b”, “TIMEOUT(digit)=3”) in new stack
– Digit timeout set to 3.000
– Executing [s@ivr-1:10] ExecIf(“SIP/781-0000014b”, “1?Background(custom/austin-greetng&custom/austin-greetng)”) in new stack
– <SIP/781-0000014b> Playing ‘custom**/austin-greetng.ulaw’** (language ‘en’)

Calling IVR from external:

-- SIP/Telecom-00000152 answered SIP/781-00000151
-- Channel SIP/Telecom-00000152 joined 'simple_bridge' basic-bridge <a1d47809-e44c-48df-aee9-2c7f05ae09f5>

(Ponos) #8

Forgot to mention both a ulaw and an alaw version of the greeting exist on the server.


(Ponos) #9

I have attached a Wreshark flow sequence (IP redacted) for an external call to the IVR


(Itzik) #10

Can you post your Trunk config?


(Ponos) #11

Sure,

Outgoing:

username=User
type=peer
secret=*********
qualifyfreq=60
qualify=yes
nat=force_rport,comedia
insecure=very
host=sip.telcom.com
fromdomain=sip.telcom.com
dtmfmode=auto
disallow=all
context=from-trunk
canreinvite=no
allow=ulaw&alaw

Incoming:

type=peer
qualifyfreq=60
qualify=yes
nat=force_rport,comedia
host=sip.telcom.com
fromuser=User
fromdomain=sip.telcom.com
dtmfmode=auto
disallow=all
context=from-trunk
canreinvite=no
allow=ulaw&alaw


(Itzik) #12

The only difference I see between the external and internal call is, that the external call played the recording in alaw and the internet in ulaw.

So try changing this:

To:
allow=ulaw

(remove the &alaw)


(Ponos) #13

OK, removed &alaw on both incoming and outgoing, unfortunately it did not resolve the issue.

I am going to have a troubleshooting session with our network admin tomorrow to step through this.

The sip provider indicated "Our RTP servers operate on ports UDP/16384 - 49151 ". My FreePBX is configured to use RTP 10000-20000 and I suspect the firewall is configured likewise.


(Dave Burgess) #14

Important theory note: your RTP range is for your end of the conversation, theirs is for theirs. Unlike traditional telephony, both legs, inbound and outbound, should be treated conceptually as separate and distinct beasts.

One-way audio is almost always a NAT issue or a codec issue. If you’ve narrowed down the codec side, the only other reasonable area of concern is something in the NAT setup. A SIP debug of the conversation (with an optional wireshark session) showing the addresses being used for the conversations (one inbound, one outbound) should give you some indication of where the traffic is getting lost.
