acme nat traversal clue
by mewash＠gmail.com Oct. 7, 2009

Oct. 7, 2009

hi guys, need a bit of help... have never touched an acme before so i'm not sure what to tell the people i am dealing with, and they seem incapable of resolving the problem themselves. trying to explain the difference between layer 3 and layer 7 is not working. setup: i have an ip pbx with a single interface at 10.0.1.80, and a netscreen 50 with a static routable ip natted to the pbx at 1.1.1.1 (sip alg is off). my itsp has an acme at 2.2.2.2. this is what an inbound call looks like right now: 2.2.2.2 -> 1.1.1.1 invite sip:xxxxxx at 1.1.1.1 <sip%3Axxxxxx at 1.1.1.1> 10.0.1.80 -> 2.2.2.2 100 trying 10.0.1.80 -> 2.2.2.2 200 ok (contact: sip:xxxxxx at 10.0.1.80<sip%3Axxxxxx at 10.0.1.80> ) 2.2.2.2 -> 10.0.1.80 ack sip:xxxxxx at 10.0.1.80 <sip%3Axxxxxx at 10.0.1.80> so obviously it breaks at this point. according to them, they are unable to configure the acme to respond to the originating routable ip instead of the nonroutable ip in the sip contact. this is what someone at acme told them: It?s not a configuration issue, the endpoint at 1.1.1.1 has set it?s contact header address to 10.0.1.80 in it?s 200 OK response back to 2.2.2.2 (SBC). The SD will look at the Contact header in order to determine where to send future in-dialog requests such as ACK, BYE, Re-INVITEs etc (according to RFC3261). Please can you check why 1.1.1.1 would be doing so? this sounds irrelevant to me, since any sip endpoint will set its contact header address to its own ip. sounds like this guy is saying "well it's natted so that won't work, tell them to fix it." i certainly can't configure my pbx to respond with a modified contact header. can anyone provide some guidance here? or maybe i am just wrong and it is impossible to make this work. but it looks like a basic hnt situation to me. thanks, milosz

Will the enterprise option give you a good understanding of Cisco Unified Communications Manager Express 4.1 (Cisco UME) and Cisco Unity Express (CUE) as well? -----Original Message----- From: Chad [mailto:cln at cln.cisco.com] Sent: Monday, September 28, 2009 1:27 PM To: Dossouvi, Rod CTR (FHWA) Subject: [CCNA Voice Study Group] New message: "Re: CCNA Voice Crossroad" Rod, A new message was posted in the thread "CCNA Voice Crossroad": https://cisco.hosted.jivesoftware.com/message/35454#35454 Author : Chad Profile : https://cisco.hosted.jivesoftware.com/people/cfogg at e-rewards.com Message: -------------------------------------------------------------- Hello Francisco, ? ? The new CCNA Voice Certification enterprise option assesses skills/knowledge related to the Cisco Unified Communications Manager 6.0 (CUCM 6.0). It is typically employed by large organizations such as governments, large companies, and colleges. ? The CCNA Voice Certification commercial option continues to use the IIUC #640-460 exam and assesses skills and knowledge related to the Cisco Unified Communications Manager Express 4.1 (Cisco UME) and Cisco Unity Express (CUE), solutions typically used by medium & small organizations such as companies with less than 2,000 employees, retail businesses, and small school districts. ? ? My thought is to go through the Enterprise Option because the will open up bigger opportunites for you, but is more widely used that the commercial option. Unless, you are just getting the cert. to put behind your name. If you are passionate about getting your CCVP and want to extend your career more in that field, then doing the Enterprise option is the way to go. -------------------------------------------------------------- To reply to this message visit the message page: https://cisco.hosted.jivesoftware.com/message/35454#35454

Open source SBC Solutions?
by ltannenbaum＠acmepacket.com Oct. 2, 2009

Jonathon, I am not sure your exact needs re capacity, but we do have a very low cost SBC software only SBC. When we acquired Covergence we picked up a full feature SBC which will do all of your needs out of the box (or off the shelf - so to speak). This is a software only feature and is called the NNOSE. Acme packet does not sell this software directly and it can only be purchased through our channels of distribution. It starts at about $3K for a minimum configuration for about 25 sessions. Its maximum capacity is 500 sessions and you can upgrade in blocks of 10 (maybe it's 25)? Anyhow, it is a known product which requires little to no work to make work. >From your list of needs below, it would appear that the opensource stuff won't fit your bill. Anyhow, I am happy to assist if I can. Good luck.

It doesn't perform exactly the same role as an SBC, but often can provide a base set for functionality like transcoding, CDR centralization, or topology disguise.

Fwd: Open source SBC Solutions?

Take a look at FreeSwitch, it can provide a bunch of what you need, and others are using it as an SBC also. Here is what need: > - Voice and video support > - Proxy > - B2BUA > - NAT Traversal > - SIP > - CDR > Does ALL of these.... > These things would be nice: > - H.323 support > yup, mod_opal > - Transcoding > yup, you may need to purchase some codecs ( from 3rd parties ) > - Simplified Management > guess this is subjective.. but little in the way of GUI's for it. config files are easy though What is not needed: > - Auto Attendant - Conferencing > Has VERY Good conferencing for what its worth > - Stateful fail-over > yea it dosnt have this, which id love personally. Id seriously suggest you look at FreeSwitch its got a great community, and its very well designed. out of the box the default config is more PBX like, but Freeswitch is a platform for you to build upon. you just need to learn to configure it how you want. Feel free to email me any QN's -- Sincerely Jay

Does anyone have a recommendation for a SBC solution based on open source software? I am looking to implement a small SBC, and there isn't much of a budget. If anyone has any specific experience one way or the other with the available solutions I would like to get your feedback. Thanks! -Jonathan

Anyone can comment how Microsoft OCS handles nomadic emergency calling and in two situations: - when a enterpise user moves to a different office say in a different city still on-net and - when travelling on the road in a hotel calling from a laptop softclient. Thanks, -guy
