Shoretel/Mitel phone systems and generic SIP trunking
by nelsonh＠socket.net Feb. 14, 2019

Feb. 14, 2019

Hello, We've had a small but growing number of customers or leads with Shoretel/Mitel phone systems that want SIP trunking, but when we begin trying to setup and test trunking, we're being told they can't configure how the SIP trunking behaves, and that for the vendor to get support, the ITSP needs to be signed up for their Center of Excellence and qualify our SIP trunking with them. One customer says they are using a "MiVoice Business vMCD or 3300 with a MBG Proxy server in server-gateway", the other a "MiVC_Connect_Build_21.90.4127.0". I'm told a couple others are using ShoreTel phone systems, but I haven't seen details for those yet. We're mostly just using Broadworks for SIP trunking, and we've provided SIP trunking for Mitel systems in the past. Does anyone have experience with continuing to make these systems work with generic SIP trunking, or experiences like I've described above? Thanks, -- Nelson Hicks Network Operations SOCKET (573) 817-0000 ext. 210 nelsonh at socket.net

RTP Proxy TTL Behavior
by ciscoplumber＠gmail.com Feb. 11, 2019

Feb. 11, 2019

We are occasionally running into a situation where our IP Header TTL expires in transit for RTP streams. It has been our observation that our SBC B2BUA that anchors media is not resetting the TTL on RTP packets but is on SIP packets. Is there a standard expected behavior for how SBC B2BUA with media anchoring might handle RTP packets? I would have thought if it resets the SIP packet TTL it would also reset the RTP packet TTL. Thoughts?

Charter Porting Department
by voiceops＠ics-il.net Jan. 15, 2019

Anyone have a contact at Charter's porting department that knows their ass from a hole in the ground? Doing our first port from them and they're not promptly responding to requests for us to get set up in their system. "To register your company for the use of this portal, please contact us at Charter.STL.LSR at charter.com to request a Trading Partner form." I did, and they responded once, but they were clueless. It's been a week since we started this process. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Blocking 911 calls
by caalvarez＠gmail.com Nov. 13, 2018

Nov. 13, 2018

Yes, I know, "you can't," but there have to be exceptions. I just can't find clear answers. We have some companies with locations outside the US, and they will occasionally dial 911 by accident. Is there any reason we can't block the accounts outside the US from dialing 911? Of course, there's the possibility that someone brings a phone here or uses a softphone account on a US phone. That "shouldn't" happen. What do others do for users outside the US? If it matters, the users are in Mexico and Philippines, mostly, occasionally in other countries.

Oracle (Acme Packet) help
by matthew＠corp.crocker.com Nov. 13, 2018

Nov. 13, 2018

Hello, Does anyone know if I can do some basic call routing on an Acme Session Director? Basically I want to build a dialplan to route calls to various session-groups based on the SIP URI. Example: 911@* goes to SAG:EMERGENCY, 011*@* goes to SAG:INTERNATIONAL, +1*@* goes to SAG:LONGDISTANCE, etc. I?m trying to avoid bouncing the calls through something like a Kamailo or freeswitch to process and 302 Moved the call back to the Acme. Thanks -Matt

Cellular Services
by Adam.Vocks＠cticomputers.com Nov. 7, 2018

Nov. 7, 2018

Anyone on the list providing cellular voice and data services to subscribers on a small scale (a few small town's of population 10k.) As I'm traveling in the Caribbean and see these other networks popping up on my phone, I'm interested in learning more. Is it practical/profitable to provide small geographical cellular areas and create roaming agreements with others for ubiquitous coverage? Anyone doing this that wouldn't mind sharing some knowledge, please let me know. Adam Vocks CTI Fiber

Outbound Fax Service
by dave＠socket.net Nov. 3, 2018

Nov. 3, 2018

All, We currently offer a home-grown outbound fax portal product. It handles PDFs or TIFFs and works okay, although it runs into problems with large PDF files. It isn?t a big draw but we have a handful of active users. We?ve looked at several commercial products in the past and it always looked daunting to get up to a volume where we could cover fixed costs. Before I invest time in overhauling our code it I?d like to hear what you?re using or if you?re even offering something similar. Thanks, Dave Sill Manager of Business Intelligence and Automation Socket Telecom
