[Spce-user] No Audio from VoiceMail System

[Stephen Donovan]

I'll chime in as the host of one of the vm setups tested with Jeremie. It wasn't nice. Sipwise is very sensitive to storage latency. It will not run on shared storage consisting of 7200 rpm desktop SATA drives. I suspect it would run fine on lightly loaded shared 15k sas drives fine. What we found was even 100ms of storage latency would kill sipwise to the point of dropping calls. I now run it on a physical server with 15k sas drives in raid 1 and have no issues and believe in a true carrier class installation this is how it should be. I'll keep my vms for running pbx instances, mail servers and internal systems. They do a good job of that. Anything database / disk io intensive needs something a little more dedicated.

My response was not to prove or disprove the merits of running your business on a VM. It was merely to illustrate my experiences. I have run sipwise for about a year and a half and have learned the ins and outs of having it to run well. Out of the box sipwise works and works well. It will handle the load they say it will and not break a sweat. In my experience it works best on a physical server but in your situation if it works well as a VM that's great. If you need help I would be glad to help. Also Kevin is very knowledgable in everything sipwise.

If you are in need of a home for your SIP Wise on a dedicated 16G/ 15K SAS Drives.

We offer dedicated Sipwise servers.

I do not want to conflict with the mailing list rules for a commercial post so I am just making a broad comment.

We have solved a lot of Sipwise issues for consumers with dedicated servers.

We tested our sipwise on several VM style setups from amazon to linode and an in house VM with very poor results. Even with a light load we were able to crash a linode servers hard drives. If you want to truly provide high quality service put sipwise on a physical server with 15K rpm sas drives and it will handle whatever you throw at it with ease.

everything is working fine so far as an ITSP configuration

but from a Provider of just telephony to a test client where they have an ATA connected to our cloud hosted Amazon EC2 instance of SIP:Wise we are not getting any audio from SIP:wise to the client when we go to voicemail or dial ext 2000 to access voicemail

i did a tcpdump and noticed that we are getting audio from the client to the SIP:wise system but not the other way.

i wonder if this has something to do with NAT as EC2 makes us put our server behind their OpenStack style 1:1 NAT. I did change the advertised-ip so everything is working currently very well for just plain calling inbound / outbound from our in-house PBX to SIP:wise.
