Just checking you have your E1 timing set to slave off the upstream.

This is the bit I mean, but if you have calls going over the E1 that are 
okay then its probably not this.

Hello,

Work well with kvm and centos 7.
Some ajustements has to be made with systemd.

I'm using it in production since 1.5 year now, no issue to report.

We install Asterisk Version 13.1 on VmWare with Debian 8.2, no

with network-manager (problem of stability with Asterisk 1.8.32 and

I also installed Asterisk on KVM (Debian 8.2) no problem (but not test with

Personally I am about to try asterisk on proxmox using containers since they 
run code "native". I've had timing issues on conference calls (stutter) with 
VMware esxi . Not sure about KVM I hope it's also better than esxi too.

Hi Josh,

Sorry to hijack this thread.

We are using AsteriskNOW, and I went to update the other day (current
11.14.2) but it seems there's no up to date versions of Asterisk 11
in the repo's that come with that distro.


Older AsteriskNOW (5.211.x) uses a separate repo and is not kept up to 
date as of this time.



I'll assume Digium is keeping theirs up to date, but do the Asterisk
updates in AsteriskNOW come from the CentOS repos?


Newer AsteriskNOW (6.12.x) uses a different non-CentOS repo and is kept 
up to date. I don't believe there's an upgrade path between them. As for 
a repo to use - FreePBX bases their distro on CentOS so theirs might be 
best for you.

Rule One:  Start your own topics -- don't jump in on someone else's, unless 
it's actually relevant.

Rule Two:  Type your reply *after* the thing you are replying to.


Your SIP trunk provider will know how to connect an Asterisk box to them.  
That, after all, is what most people are going to be connecting.
