She's breaking up she's breaking up!

Post by FogWatch » Wed Apr 10, 2019 2:39 pm

She's breaking up, she's breaking up!

For last few months people I phone inconsistently say that they receive a crackly or broken audio from me. It is about this that I write.

My ping stats are almost always excellent:

Code: Select all

--- sip1.exetel.com.au ping statistics ---
16 packets transmitted, 16 received, 0% packet loss, time 35ms
rtt min/avg/max/mdev = 7.289/7.733/8.307/0.260 ms
The CPUs on my Asterisk (13.23.1) box rarely get out of bed.

What should I do to narrow down where the problem lies?

What is the handset type you use? Any chance of comparing with a known working standard corded handset connected with the VOIP configured modem?

I use corded (SIP) and cordless (FXS). Over time, the inconsistency in uploaded crackly audio appears to be consistent between the handsets.

Not really, and I'm not sure what it would show.
The crux of the question is, is there anything I'm doing at the time of uploading crackly audio that I shouldn't be in comparison to when sent audio is clean, or is the cracklyness caused further down the line out of my control?

HI,

We have checked this issue with our Level 2 VoIP engineers and they have suggested few things to be tested.

1. kindly make sure that your codecs in use on the VPBX is "allow=alaw & ulaw (G711)"

2. Kindly make sure and recheck the following configuration as well on your device

source IP/Port ranges used by Exetel.

IP Signaling IP Ranges

    - 58.96.1.2

SIP IP/Port Ranges

    - 58.96.1.0/27 - 5060

    - 220.233.0.0/25 - 5060

    - 58.96.8.0/26 - 5060

RTP Port Ranges (UDP)

    - 58.96.1.2 -> 50000-60000

    - 58.96.0.0/17 , 220.233.0.0/25, 115.70.0.0/26 -> 10000-20000

3. If issues still persists would you be able to test the service on an alternative PC using a softphone?

4. Kindly also check if your internet bandwidth is not over utilized at the time of the issue. If you are experiencing any issue with the internet let us know as that needs to be resolved first.

Thank you
