One Way Audio Issues and STUN
-
@krisleslie what issues are you encountering?
-
@dustinb3403 as of today 1-way audio.

on internal ext to ext calls? Because if not that, then the problem is unlikely to be the phones.
-
Granted 1 way audio is almost never the phone anyway.
-
Intra-office calls (so far) are fine no issues. Someone dialing in from outside of our network has the issues mostly.

Can they hear you or can you not hear them?
-
@dustinb3403 well right now I'm wondering is there an issue with the STUN server or is there a firewall issue between me and the STUN server. I've used the common one on the internet:
-
@dustinb3403 my receptionist can't hear them, however I confirmed she is being heard.
-
So inbound one-way audio issues.

So, I assume that you have an internal PBX and an external SIP trunk.
If so, this is a firewall / NAT issue.
Edit: wow, shoudl probbaly make a different thread.

Cloud hosted. I will make a new thread. I apologize.

Ok, so one way issues should happen on ext to ext calls too if it was your firewall. It should not be "only" on external calls.

@JaredBusch I might've missed it, but is @krisleslie system hosted offsite on vultr or some such place?

It's on Rackspace.

This may or may not help.... I ran into a SIP issue last fall at one of our sites. I found IPS triggers in the logs and created an exception in the IPS which fixed the issue.
This started as a one way audio issue.
Here's a cap of the signature database description. We use Watchguard appliances.

Scott I caught an article on that also this morning how SIP/ALG and IPS need to both be off. Why is it that the things intended to make things "better" tend to need to be off lol. Then when we add STUN to the equation it can also negate any other changes made due to it!
-
The SIP/ALG I forgot to turn off last night as I was too busy trying to test out my WDS server
If I stay late tonight and the office is clear, I'm disabling that ALG it seems to be the common cause of all issues and then as far as IPS getting disabled on the Edge Router I dunno how or even if I should!
-
Hackers are probing us just not in high volume.

ALG should normally always be off, and Jarod always disables in on ER devices. We've had good luck in it not breaking there (it definitely breaks on every other device we know of.) ALG is not designed to fix anything, AFAIK, it is literally intended to break SIP, it's never fixed anything and there was nothing to fix.
