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.

We've recently been issued a CLEC license in the state of New Jersey and I'd like to leverage that to secure phone numbers for my customers. Who would I need to contact about Interconnects and how would I go about getting a block of numbers assigned to my company?

Perimeta SBC & TCP
by dsarvai＠dscicorp.com Dec. 17, 2015

Dec. 17, 2015

Group: I am trying to complete a conversion from Acme Packet/Oracle SBC to Metaswitch Perimeta SBC. We found late during the cutover process that Polycom/Metaswitch hasn?t implemented a common TCP strategy to keep firewall TCP sessions/connections alive. Has anyone in the group successfully implemented a TCP strategy and if so, am I missing anything? With the ACME topology, all phones do the following regardless of protocol to maintain pinholes through firewalls: 1 SEC Phone -> Register -> Firewall -> SBC -> Register -> Broadsoft 1 SEC Phone <- Register (expire 60 Seconds) <- Firewall <- SBC <- Register (Expire 1 Hour) <- Broadsoft 60 SEC Phone -> Register -> Firewall -> SBC 60 SEC Phone <- Register (expire 60 Seconds) <- Firewall <- SBC Polycom: Requires use to frequent SIP registration (maintained by Perimeta) to keep SIP pinholes through firewalls alive. Metaswtich: Requires TCP clients (Polycom) to maintain pinholes using native TCP keepalive syn/ack messages. Polycom?s implementation of ?TCP keepalives? is only applicable if the phone is using TLS. There is no such setting for non-tls TCP based traffic. So the phone will establish a TCP connection to the SBC, and then site dormant if no registration/call/subscription messages traverse. The firewall will close its ports, and the phone will lose connectivity. Metaswitch has a fast-nat feature, which is used to shield switches from UDP based registrations. When enabled, fast-nat modifies the endpoint expire timer to allow the endpoint to re-register (keeping the firewall session alive). For UDP, this works correctly, and the SBC responds to the endpoint with a 200OK. But for TCP, the SBC passes the re-registration attempt back to the switch. TCP Metaswitch Example with fast-nat: 1 SEC Phone -> Register-> Firewall -> SBC -> Register -> Broadsoft 1 SEC Phone <- Register (expire 60 Seconds) <- Firewall <- SBC <- Register (Expire 1 Hour) <- Broadsoft 60 SEC Phone -> Register-> Firewall -> SBC -> Register -> Broadsoft 60 SEC Phone <- Register (expire 60 Seconds) <- Firewall <- SBC <- Register (Expire 1 Hour) <- Broadsoft My question to the group, is has anyone implemented TCP based registration using Perimeta and Broadsoft?

BellSouth subscribers have been having issues connecting to some of our numbers in Florida. I have made some routing adjustments and want to retest, however I don't have a BellSouth line and haven't been able to get a hold of the original callers having the issue. Anyone on list have a Bell South line that would be willing to place a handful of calls to the below test numbers? 19545192486 19545192496 19545192494 They should connect to caller-ID read back and echo line. If you're able to place some calls, let me know your results. -- JUSTIN GROW OPERATIONS MANAGER <https://www.flowroute.com> O: +1.206.641.8038 jgrow at flowroute.com
