Firstly. There were many itsp's I have used with sipx (using ingate session border controllers).
There were several ITSP's I found too difficult to use at all and nexvortex was one of them. Nice guys, just up the road here, but I had continual issues with them and had to pull the plug. That was a couple of years agao and maybe things have changed for them. I recall some upstream issues with certain carriers always being an issue. I did lots of traces and pcaps. I just started using itsp's that had better answers for what I needed. http://blog.myitdepartment.net/?p=127 Continued... ============================ Tony Graziano, Manager Telephone: 434.984.8430 Fax: 434.984.8431 Email: [email protected] LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 Fax: 434.984.8427 Helpdesk Contract Customers: http://www.myitdepartment.net/gethelp/ ----- Original Message ----- From: [email protected] <[email protected]> To: [email protected] <[email protected]> Sent: Wed Oct 27 13:50:35 2010 Subject: [sipx-users] Inbound Verizon Callers I work for a small non profit and we have begun using sipX in an office in Everett,WA. We have 8, 2 line polycom soundpoint 331 phone. We use NexVortex as our service provider with 4 DID's. Just after moving to this system we noticed some calls would ring once and then disconnect. We did some testing and discovered it was isolated to Verizon Wireless callers. I have yet to figure it out. I have had 3 T- mobile customers call, 2 AT&T, 1 Sprint, and 5 Verizon. I have tried 7 land lines. Aside from those about 20-40 calls a day in and out of the system work. Callers that have show as "failed" or "Abandoned" in the CDR when called back say they are Verizon and report the same issue, "It rang once then hung up". Two of the DID's go to hunt groups that simultaneously ring all phones. If no answer the Hunt group falls to x200 and hits a general mailbox. One number is an Alias that is Assigned to a user, which is the user on line 2 of all 8 phones. The fourth number is really just for me to test with. Yesterday I did some testing on routing the call different ways in our system using one number. 1) I sent callers to a hunt group = Verizon callers got disconnected. 2) I sent callers to auto-attendant = Verizon callers got through, entered an extension and calls were answerable by our users. (if no answer it went to voicemail) 3) I sent callers to a user directly = Verizon callers got through to that extension. (if no answer it went to voicemail) So if I send them to a hunt group, the call doesn't work, If I send them to a user assigned to all the phones, it doesn't go through. If I send them to 1 user or to auto attendant, the call goes through. Any ideas or advice? sipXconfig (4.2.0-018575 2010-04-15T00:40:11 ecs-centos5) I Installed from an ISO. When I last tried to upgrade various services stopped functioning.
