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.

Unique DIDs vs. Custom extensions
by rafaelpossa＠gmail.com Oct. 6, 2015

Oct. 6, 2015

Hello all, I was tasked to design a system that would give each end user a unique DID from a pool of about 1,000 DIDs total. Every inbound call to a DID would then be forward to the end-users actual phone number (office, mobile, etc..). We would then make data driven decisions based off of the data collected from all these inbound calls: duration, originating area codes, how many calls, frequency, etc.This of course would have previous authorization of each end-user. WIth that in mind, to me it looks like a big waste of DIDs, and I could use custom extensions instead, with a single DID for everyone. Each end-user is assigned a 5 digit code (an extension pretty much) and gets re-routed accordingly. I believe using Asterisk and/or FreePBX I could still collected all the data that is needed. Estimated inbound minutes is 500,000 a month, so that requires another 500,000 outbound minutes because each call is forwarded. One million minutes a month does turn out to be expensive, close to U$8,000/month from some quotes that I have gotten. With all of this in mind, I'd like to know if anyone here has done a similar project and would be willing to share their experience. I am trying to accomplish everything with the minimum amount of resources as possible (money and DIDs, etc). Thank you in advance! Best regards, Rafael

Full Mesh Voice and SMS Testing
by beckman＠angryox.com Sept. 29, 2015

Sept. 29, 2015

I'm curious how people test Voice and SMS connectivity for their DIDs, and how often these tests are done. I currently have a system in place that tests Voice connectivity using a specific valid-but-unused CallerID value, and I place calls through off-net carriers to my DIDs in order to ensure call completion. Additionally I am using an off-net SMS provider to test that SMS connectivity works to my DIDs. Is anyone doing regular, ongoing, full mesh tests for Voice and SMS connectivity? E.g. For a Verizon DID, you might do a test call from AT&T, AT&T Wireless, Sprint, T-Mobile, Level3, Comcast, CenturyLink, Cox, Charter, Windstream, Frontier. For SMS, you might test from the big 4 plus an offnet SMS provider like Plivo, Twilio, Nexmo, etc. I'd love to hear how you ensure high quality customer experience behind the scenes, fixing problems BEFORE the customer knows there is one. Obviously an incoming call or SMS to a DID is usually enough to not warrant a test. But for quiet DIDs, what do you do?

Anyone seeing issues with Verizon and no audio/poor quality? We are seeing it across 11 local gateways across the US. Inbound TF trunks appear ok so far.

Seeking phone system recommendations
by graham＠nerdventures.com Sept. 29, 2015

Sept. 29, 2015

Hi, folks, Can you recommend a managed telephony vendor? Client characteristics: * Several locations in the US, in multiple states. * Total of a few hundred seats. * High tens or low hundreds of thousands of minutes. * Prefer to trunk to vendor via existing reliable multi-hundred-megabit and/or gigabit internet connections. Dedicated link is a possibility if necessary. * Ideal to continue using existing Polycom SIP phones. * Vendor should have monitoring that is as proactive as possible. SIP packet loss? Call drops? Call completion failing? Low MOS scores? To the extent technically and commercially feasible (IMO, it's feasible), vendor should be the first to notify client about these issues and path/timeline to resolution, instead of waiting for client to complain. * Operator panel that is at least as capable as Shoretel Communicator (version 13). Ideally modern HTML5 web-based, not based on ancient vulnerable tech (such as Flash or Java). Client has a good IT team, including folks with telecom experience, but would rather have a managed telephony vendor instead of staffing up more telecom expertise internally. Client prefers to handle end-user tier-1 (and sometimes tier-2) helpdesk issues internally, and have in-house IT/telecom staff talk to telephony vendor about any issues that can't be handled internally. (In other words, this is a great client for a telephony vendor that can build and maintain a reliable and properly monitored telephony infrastructure.) Client is accustomed to deploying phones with LLDP-MED, putting phones on a separate voice VLAN with a vendor-managed router handling that VLAN. Client would love to see provisioning (e.g. new phone) and management (e.g. password resets) as automated as possible. Current vendor has a very manual (and time-intensive and error-prone) process. If you respond via email off-list, I'll summarize the responses on-list in a few days. (Please, don't call or text me about this unless we've made an appointment to discuss.) thanks, Graham Freeman, Principal Nerd NerdVentures.com graham at nerdventures.com https://www.linkedin.com/in/grahamfreeman Twitter: @get_nerdy

Troubleshooting SMS Delivery
by beckman＠angryox.com Sept. 23, 2015

Sept. 23, 2015

I'm having trouble with a very specific SMS deliverability issue. I've built a little system that tests all of my DIDs to ensure SMS deliverability and measure round-trip time. 1. I have 3 DIDs from Carrier A; LRN says Bandwidth.com. Used as Test Source DIDs. 2. I have 20-30 DIDs from Carrier B: that do not receive SMS messages sent from #1 DIDs; These DIDs LRN says Bandwidth.com. Used as Test Destination DIDs. 3. SMS messages sent from Carrier A DID to Carrier B DID are never received Bandwidth won't talk to me about this issue because the DIDs involved are not in my account. Frustrating, but understandable. The question that I can't seem to get either direct carrier to answer is who is in the middle. Carrier A reported: "Our SMS carrier investigated the SMS delivery issue to the numbers you reported and confirmed that they are routing the messages correctly but these are intentionally not being delivered to the TN's (Terminating Numbers) by the terminating carriers. They say that if any of these receiving parties are stating that they should be receiving any messages, they will need to reach out to their provider." Well, _I_ am the receiving party, and despite tickets open with both carriers for 3 weeks, I'm getting no where. Carrier A won't tell me what carrier is "intentionally not" delivering SMS messages. Anyone on list have any insight?

WiFi SIP phones recommendations
by shripald＠gmail.com Sept. 22, 2015

Sept. 22, 2015

Hello All, I'm looking to implement 6-10 WIFI phones for a 3 floor restaurant using unifi AP-PRO's. i'm not sure if they are using zero handoff on the AP's, but i'm sure they can implement, if they need to. I was wondering if anyone has any recommendations for a good (and simple) SIP Wifi hadsets. we wanted to use a yealink w52, but because the repeaters only support one base, it wont work for this implementation. Customer is coming off a call manager with Cisco 7925s, which are really solid, but we can't support them. Thx Shri
