CLEC - SIP handoff from the LECs
by ryan＠finnesey.com May 2, 2016

May 2, 2016

Yes I do think there will be an opportunity to partner with CLECs and also deploy our own network. In the end I think it will be a bit of a hybrid. For the fax service we would like to use are own NXXs But one area I see opportunity to work with CLECs is around Office 365. The local CLEC can provide SIP and network connectivity. We developed an appliance that would enable hosted PBX services to run out of the Office 365 data centers but the voice traffic be routed to the CLEC. I would think a win win.

ILEC interconnect still require plain old TDM . But you can partner with other CLECs like us to share cost of TDM connectivity, without committing to investment in TDM switch and transport. Thanks, Naush Good Evening Is it possible for a CLEC to get a SIP handoff from the LECs or is TDM still requested?

Recommendations for high-cps SS7 OC-X gear?
by bbridges＠o1.com April 25, 2016

April 25, 2016

Looking for suggestions for NEBS compliant gear that can support SS7, handle OC-3 or higher levels of channels, and can support (in aggregate) up to around 500 cps through a *good* (key word) SIP interface. I'm willing to entertain the idea of a single larger device that can take a full OC-48 and support the full 500 cps, but I'd prefer spread the load across multiple devices and smaller interfaces for load balancing and redundancy. Any pointers? Obviously there are products out there by the really big players, but I'd really rather not have to drop 7 figures on this project unless I have to. Thanks!

Hi Y'all, I'm testing some updated routing in the Dallas, TX area. If anyone on list has ATT landlines in LATA 552 that can place some calls to the below numbers and let me know your results, it would be greatly appreciated. Feel free to send responses off-list. These numbers should connect to a CID readback and echo line. 8178989608 8178989040 Regards, Justin Grow Operations +1.206.641.8038 jgrow at flowroute.com

VoiceOps Digest, Vol 82, Issue 18
by jaredball1＠gmail.com April 20, 2016

April 20, 2016

Does using Kamailio and the dispatcher module require programming? Is this a matter of reading the documentation and some configuration or does this involve writing a script for handling any SIP dialogue that might come my way? I want to implement this in 3 - 6 months. I don't want to embark on an 18 month research endeavor.

Load balancing SIP
by Aaron.Sykes＠cdk.com April 19, 2016

April 19, 2016

Has anyone had any success load balancing SIP? More specifically distributing SIP registrations across a number of access SBCs and maintaining persistence based on source IP. By maintaining source IP persistence subsequent calls would go to the SBC to which they are registered. In this case each of several SBCs cache registrations for a single SIP registrar. Has anyone used F5 or Kamailio for this..or some other SIP proxy or load balancer?
