I am thinking about using the G729 codecs on my endpoint devices and purchasing some G729 licenses for Asterisk but I have several questions: 1. Which G729 codec is sold by Digium for Asterisk, G729, G729A, B...I? 2. If I have G729A on one end and G729B on the other, are they compatible? I have looked all over the place for question 2, but without buying the ITU docs I cannot seem to find this

Has anyone experienced any date/time problems on Asterisk? I have noticed it on earlier builds and I believe on this build: CVS-02/16/04-23:57:06 Specifically, I have seen the following problems: 1. Change system time using the "date" command while Asterisk is running. Asterisk does not synchronize with new system time. 2. Daylight savings time goes on/off at the designated

I am wanting to perform toll bypass using multiple gateways for outgoing calls. For example, if I call from location A to location B and I have a gateway in location B I obviously want to use location B's gateway to make it a local call. I understand how to get the local prefixes from NANPA but my question is: If there are additional numbers that are local (non-toll) calls from a particular

Hello All, As you will inevitably discover I am new to Linux, not to mention Network Admin, but enjoying the ride. ? I've added a Redhat 6.2 server to?our?NT 4.0 domain.

I''m trying to get Puppet to run on ESX v3.0.1. Being that ESX doesn''t come with ruby, I installed v1.8.6 under /opt/ruby/ruby-1.8.6 and linked the bin to /usr/bin. facter installed and runs without issue. However, when I try to install puppet, I get: - Could not load openssl; cannot install Is this due to the way I installed ruby or something else? Thanks, Clif

Hi, I have more or less decided to do with the SNOM phones for the next stage of testing with Asterisk becasue they seem to be the best value for money and have support for the GSM codec and easy upgrades.. But now I have to decied wheather to get the 100 or 200 and if its the 200 then I need to have some justification for the extra cost.. Can someone who knows these 2 phones tell me what the

Hi , I have two virtual machines VM1 and VM2. Then I have added eth0 of my VM to 'default' network. Use case :- I want to monitor all traffic on virbr0('default' network). Steps followed :- 1. Add VM1 eth0 to virbr0 2. Add VM2 eth1 to virbr0 3. brctl setageing ovsbr0 0 ..(To put bridge in promiscuous) Now I am running tcpdump on eth1 of VM2 and trying to ping

In my vm2 config i have: disk = [ ''phy:/dev/volumes/vm2-disk,hda,w'', ''phy:/dev/volumes/vm2-swap,hdb,w'', ''phy:/dev/volumes/vm2-data,hdc,w'', ''file:/xen/images/office2007basic.iso,hdd,r'', ''file:/xen/images/printshopinstall.iso,hde,r'',

We used to stop the handling of tx when the number of pending DMAs exceeds VHOST_MAX_PEND. This is used to reduce the memory occupation of both host and guest. But it was too aggressive in some cases, since any delay or blocking of a single packet may delay or block the guest transmission. Consider the following setup: +-----+ +-----+ | VM1 | | VM2 | +--+--+

[It may be necessary to remove virtio-dev at lists.oasis-open.org from CC if you are a non-TC member.] Hi, Some modern networking applications bypass the kernel network stack so that rx/tx rings and DMA buffers can be directly mapped. This is typical in DPDK applications where virtio-net currently is one of several NIC choices. Existing virtio-net implementations are not optimized for VM-to-VM

yes, I got your point, thanks very much Eric. If I want to take a distributed snapshot, which need pause all the VMs and then take snapshot, how can I control the pause for all the VMs? Is there only way that I turn to freeze/thaw functions? and freeze/thaw only for file systems, not for the whole guest, am I right? Thanks a lot!
