Maintenance for Performance Technologies SEGway
by scott＠socket.net May 17, 2017

May 17, 2017

We have been using a set of PTI SEGway x201s with point code emulation for a number of years now. We also have an unlicensed spare in stock. The maintenance contract renewals are due and the two quotes I've received are quite high. I know of at least one other company that has chosen to drop the vendor maintenance and take care of that in-house. I would like to hear from anyone that is currently using SEGways and find out what they chose to do for maintenance. I would also be very interested to hear of any bad experiences from chosing the in-house option. Thanks.

Homegrown SIP load testing platform
by jchleboun＠e-c-group.com Aug. 31, 2013

Aug. 31, 2013

I am interested to see if y'all have recommendations for putting together a SIP load testing platform using general purpose hardware and open-source (or inexpensive) software. We are aware of Empirix Hammer and similar solutions, and we are looking to see if there is an alternative option. Goals: - Generate somewhere on the order of 20k phone calls with real SIP and RTP. - Route the flows through our VoIP infrastructure to test performance limits. - Receive and analyze the SIP and RTP on the other end to find out at what load the signaling and/or media start to break down. Attempted already: - SIPp spread across many servers. Here the limiting factor seemed to be the CPU load from the interrupts from each packet. The CPU on the servers sending and receiving the phone calls got bogged down before the VoIP core. - We have dabbled with interrupt moderation in the NIC drivers, but this has not seemed to help very much. Looks interesting: - Has anyone had success using PF_RING with Direct NIC Access and libzero from the folks at ntop? Has anyone been able to use this with SIPp or some other SIP and RTP generator? Many thanks, Jon Chleboun

Anyone using the NV3430 on T1?s with hosted phone behind Broadsoft? Would you like to share some notes and review of your experience so far please? I am also looking for some insight on using Ncommand on a VM and the best possible collector options to gather all data off the TA9xx gen 2 box including PCASH.

Porting Fees
by tim.donahue＠gmail.com July 30, 2013

July 30, 2013

Hi all, We are re-negotiating one of our carrier contracts and we have come across a new fee that we have not seen before. The carrier is looking to include a "port away" fee for when we lose a line to another carrier. Has anyone heard of this before? (Off-line replies are welcome.) Tim Donahue

We've been using Edgemarcs for years and it's time to consider a technology refresh. What's everyone using? Looking for pros, cons, and opinions. Thanks

Unless they've recently improved it the Edgewater CLI is painful or impossible for most configuration tasks.

Debugs on the Adtran also provide diagnostics and packet capture. The TA900e series has 4xT1 of which two can be PRI and two ethernet ports. With VLANs the number of physical ports isn't usually an issue, you'll typically have a PoE switch in the mix. > Both can drop a PRI but on the Edgemarc you need to run older code. > > The Edgemarc can be a regular eth router while you are limited by the > TA908 to just one eth port.

Suggestions? I'm not aware of anything else truly ready for prime time with decent support other than the various Cisco boxes but the price point there is usually prohibitive. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
