No audio both ways on internal extension during inbound call [SOLVED]

Hi,

I am currently running freepbx distro version on a virtual machine under ubuntu. Ubuntu does have its firewall off. I also have a linksys wrt54gl running as a home router with ports 5060 and range 10000-20000 forwarded to the Asterisk vm. In the same LAN I’ve got a Grandstream bt101. All CID/DID are sent into this phone (ext 200). Every now and then when picking up a call I get no audio either on the ext nor on the remote caller (remote caller calling from pstn). I tried multiple things but nothing seem to work. I have the following settings under “Asterisk SIP Settings”

externip=external ip (static in my case)
Local NEtwork: 192.168.1.0/255.255.255.0

Codecs: alaw, ulaw, gsm

I did a sip set debug peer 200 (the extension having problems) until I could reproduce the error, here is the log.

I really hope someone can help me as I do not know what else to do.

Thank you…

Edit: I noticed that not even the vm recording will be heard when calling from the pstn after the phone rang 7 seconds (as set un the ext configt). Unplugging the phone will result in 100% successful calls into vm.

Really destroying SIP dialog ‘[email protected]:5060’ Method: OPTIONS

It looks like the RTP is not being properly constrained.

check /etc/asterisk/rtp/.conf

turn off sip and verbosity then run a ‘rtp debug’ while a call is up.

Thanks for your reply SkykingOH…

Do you need me to post an RTP debug log from a working or non working (silenced) call?
Also what type of problem and where do you see it in the log that I posted?

Thanks! :slight_smile:

Edit. Let me say again that this is running on a VM (virtual box). Ubuntu is the main OS and freepbx distro is running virtualized inside of it. I am not sure this might be the reason for random silent inbound calls from pstn.

Ok here I managed to get a good rtp log for a silenced call:

Any evident problems?

You indicated that all hosts are on the same network yet the RTP stream is going to a public IP. You have some NAT issues causing your audio problems.

ok, I have rtp ports set on Asterisk in the 10000-20000 udp range and the firewall is open on the same range for Asterisk private IP (forwarded).
The strange thing is that the problem happens every now and then. In order to provide the log I came up with before I had to test maybe 7 o 8 calls.

Any thoughts on the rtp log?

Thanks.

EDIT: Doing further testing I realised the following:

  1. I make a call to the pstn number, extension is unplugged, so I get vm.
  2. Call right back and get vm.
  3. Wait 30 mins call back and no sound whatsoever
  4. Call right back, audio is back.

Well I think I found a solution to my problem. My network set up is as follows:

—DDWRT Router—VM (FreePBX Distro).

Even though I had opened all relevant ports on the router, there was probably some type of firewall already active in CentOS. I created the same rules on iptables for CentOS and put it in DMZ. Now everything works great. If I remove it from the dmz and behind nat again the problem appears in such a way that in 1 call out of 10 on average will be silent both ways.
I am not sure what is causing this, maybe double nating? In any case running the machine in DMZ with proper CentOS firewall rules seems to do the trick for me.

Thanks.
