My guess, L3 isn't terming the call themselves and at some point the converting RFC2833 to inband to hand off to the eventual term carrier, and that carrier is accepting the call via a Sonus which is mucking it up. and yes been there done that. -- Robin D.

DTMF issues for Conf Bridges
by chris.ledford＠cnxntech.com March 16, 2010

March 16, 2010

I have a switch out of the Miami and we are experiencing DTMF problems getting to 215 or 218 NPA. The call completes and then the DTMF to gain access to the conf dies. I tries INFO and RFC2833, inband, via sip, transparent all using G711 codec. No luck on anything so I opened a ticket with L3 and L3 said that the circuit is oversubscribed on the conf bridge side. Here is an excerpt from the email "...Test results confirm NPA NXX 218 862 is on the access pumping list, A known capasity issue on the Level 3 Network whare a RCC 34 is sent to customer to route away from LVL 3..." I am not sure what to the next step is....any ideas would help.... V/r Chris Ledford CCNA/CCSP/CVOICE MCP/Comptia A+/NET+/SEC+/LINUX+

Verizon issues?

Curious whether anyone else has been seeing a large number of SIP 600 Call Gapping Failure responses from SIP termination to Verizon today. Seemed to start in the afternoon though our call volume has been typical and certainly less than we've pushed through them in the past. Brian

ACME Packet Contact Header
by lriemer＠bestline.net March 12, 2010

March 12, 2010

Anyone know how to not have an Acme packet rewrite the user portion of a contact header? I do want it to rewrite the host portion to its IP. Even thought I have nat-traversal set to "none" on the external sip-interface, it still is rewriting the user portion and appending an encrypted IP. It's not so much that my switch is receiving these, it is that the Acme is caching the registration based on this rewritten contact header. Of course, this breaks outbound calls from my switch as it sends DN at acmeip, not DN-encryptedIP at acmeip. Thanks.

VoiceOps Digest, Vol 9, Issue 7

Matt, I have been working with BroadSoft for a number of years and have overall been very pleased with the stability and feature of the system. It is especially well suited to serving customers in need of hosted PBX and IP centrex services. As of late, the addition of Enhanced SIP Trunking features even gives it a leg up on the SBC or openser options. We have deployed nearly three dozen BroadWorks systems for various service providers and the vast majority of them also use the Acme Packet products for their SBC. Acme's ability to perform SIP normalization, topology hiding, and provide some pretty sophisticated DOS protections sets a pretty high bar for other SBCs when talking about HNT and peering solutions. Given the fact that BroadSoft is rolling out the AMS platform to support your existing SKINNY users, it definitely seems like BroadWorks with the Acme Packet for SIP and AMS for SKINNY support is a reasonable place to start.

Howdie, I'm the lucky (!!?) owner of a Vocaldata/Tekelec/GENBAND/Broadsoft M6 soft switch. I'm looking at replacing it with a Broadsoft Broadworks switch. Anyone out there familiar with both switches? Any opinions of the stability/feature set of Broadworks would be welcome! If you have Broadworks, which SBC are you using? Anyone using OpenSIPS to front end BWorks? Send me on or off-list responses, your preference. Thanks -Matt -- Matthew S. Crocker President Crocker Communications, Inc.
