Broadsofts BLF List URI Implementation is Unique?
by colton.conor＠gmail.com Sept. 2, 2017

Sept. 2, 2017

I asked this question in 2015, so I am wondering if anyone has an update. Is the the way that Broadsoft implements Busy Lamp Field (BLF) using list URI unique only to Broadsoft, or have any other softswitch providers now implemented this method? With a Broadsoft switch and a Polycom or Yealink phone, all that needs to be done on the phones config is to enter the BLF list URI server address. Then on the Broadsoft server you select the users you want to monitor, and the BLF list instantly updates on the phone. I think this reduces overall signaling too which is a big issue with BLF status updates. There is no rebooting or going into the phones configuration file once the BLF List URI is set. For an example on how easy BLF is setup on Yealink phones with Broadsoft see this http://www.yealink.com/Upload/UCOne/features/Quick_Setup_BLF_List_on_Yealin… Compare this to most other platforms I have seen based on Asterisk and Freeswitch. I think 3CX and Metaswitch are the same. In all these platforms, on the phones confige its self, you have to manually create a key on the phone to monitor a user. That might be done through the provisioning interface itself, but it still static adds a BLF line key to the phones configuration. Any updates to BLFs are usually not dynamic, and adding or removing a BLF requires a reboot to the phone as you have to change the config file. Example of this method on a Yealink using a Asterisk based service like Virtual PBX see this https://www.virtualpbx.com/support/dash/topics/t48g-blf/ Anyone have BLF List URI working on a non Broadsoft switch?

Alex, Great to hear Kamailio supports this! Looks like Asterisk does too: https://wiki.asterisk.org/wiki/pages/viewpage.action?pageId=30278158 Anyone know if Freeswitch supports RFC 4662? I did a Google search now that I know what I am searching for, and found some freeswitch posts from others asking if Freeswitch supports RFC4662. But no one knows if Freeswitch supports RFC 4662? I guess I could post on the freeswitch list.

* Numbers
by nick＠flhsi.com Aug. 29, 2017

Aug. 29, 2017

Greetings all, Here in the state of Florida, Some agencies, Like Florida Highway Patrol have dial-in numbers like "*fhp" (*347), Which can be called anywhere in the state. or at least anywhere in the county. I have a customer (Local sheriff's office) that would like a number like this. Something like "*SCSO" Anyone have any idea how I might go about doing this? I imagine it works similar to 311 (Non-emergency dispatch) in that, Someone carries a local translation that points it to a ten digit number. I service a few agencies that already have this and simply porting the associated ten-digit dial-to number moves their 311 dial-in service. However, I've never gone about actually getting one of these numbers. We're not facilities based, I'm purchasing wholesale SIP from a number of the usual suspects.

Verizon origination

Hello, Can anyone with a Verizon origination service do me a favor and check to see if they let you port-in and/or obtain new numbers specifically in FREDERIC, Wisconsin ratecenter. 715-566 appears to be Cellco dba Verizon but I think it may only be accessible to Verizon Wireless operations. https://www.telcodata.us/search-area-code-exchange-by-ratecenter-state?rate… If anyone has any tips to getting DIDs there, I'd love to hear. Thanks, I appreciate it! Aviv

Can't call 833 numbers from specific rate center via cell phones
by kelntaylor＠gmail.com Aug. 19, 2017

Aug. 19, 2017

I have a new 833 toll free number. Cell phones (both ATT and Verizon) in a specific rate center are not able to call this new number or other 833 numbers. I have contacted my origination provider, ATT wireless, and Verizon wireless, but I am unable to get in contact with the proper people to resolve the issue. Any ideas? Sincerely, Keln Taylor

Looking for an additional (backup) SS7 connection. Wondering if anyone can suggest a good provider that we can work with / order through. We've been trying to order another one through AT&T for about a year now, and are still no closer to actually getting it. Thanks

US Cellular - CPN showing as 1206, dropping after 21 seconds
by mwiles＠akabis.com July 24, 2017

July 24, 2017

Anyone from US Cellular on here? We're seeing calls coming in with the CPN showing as "1206", and the calls always drop after 21 seconds. We've been able to determine, after talking to the callers, that they're US Cellular customers. Anyone else seeing this or heard of it? About to drive one of our customers crazy. Mark

411 provider recommendations
by Jared.Ball＠cdk.com July 24, 2017

July 24, 2017

My company has had a long-term relationship with a 411 provider for about 10 years. We have never really had any problems. We received a letter about them no longer offering this service and transitioning us to another vendor. Can I get some recommendations on 411 providers? I might ask our caller-id-name provider if they have a 411 service. Any recommendations on providers that have had no problems for 5+ years would be appreciated. --Jared Ball ---------------------------------------------------------------------- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.

Tool To Test for SIP ALGs
by colton.conor＠gmail.com July 18, 2017

July 18, 2017

Anyone have a tool that a technician or customer could put on a computer on a customer's network, and it will tell them if a SIP ALG was disabled or enabled? Or if their network was suitable for SIP traffic? We started deploying some Ubiquiti Unifi USG routers, and discovered that they had SIP ALG enabled by default. Typically we just put the Polycom VVX phones to register with TCP for signaling, and this bypasses most SIP ALGs as I think most can only handle SIP using UDP and not TCP right? Well I guess the SIP ALG used in the Ubiquiti Unifi USG does modify even SIP using TCP. I know Ubiquiti Unifi USG use a fork of the vyatta operating system, and the command to disabled it is set system conntrack modules sip disable We were able to turn SIP ALG off, and now everything is working fine. Would be great if there was a tool a low level tech or customer could use to test the network?
