[cisco-voip] Fwd: Moving to SIP

Sun Sep 25 19:20:07 EDT 2011

I had a client with a multiple campus Iwatsu system.   We had problems with sip circuits.  Client bought a new wan and UC system.   One thing that came in first was a PRI which cured ALL problems with the Iwatsu.   Now there are some nice features with the Cisco but..............

Personally I cant see the need to change from ISDN PRI to SIP anyway.. I DON’T see the cost savings I would rather had a PRI into a switch for LOCAL calls/911!!!  and use SIP for on-net and LD calls….(and have the ISDN PRI for backup!! I JUST DON’T like putting it all in one basket…cut the internet cord and you are SOL….WHY do people do this??).

One small company locally had a Nortel KSU system with 3 analog trunks…..they changed to a NEC VoIP system…but KEPT the analog trunks!!! DUH!!! WHAT A WASTE OF MONEY!!! They get NOTHING they didn’t have with the Nortel (unless they didn’t have the CLID cards in the Nortel…BIG deal…that’s only $150 for the card…) They had CallPilot VM which does everything Cisco’s does….Someone mind explaining this to me???? I took Economics 101 in College (but I FLUNKED that course……who the hell can learn with one bloodshot eye at 7AM!???!!! Kudos to Lewis Black for that JOKE)

I am sorry but VoIP IS NOT the way to go for EVERYTHING….

I HAVE added Vonage lines to Nortel KSUs with CallPilot that gave them unified messaging and free LD….funny, the cost was MUCH LOWER than a new Cisco system and they have ALL the features….SO someone tell me…WHY???????????????????? I JUST DON’T get it….(oh you can plug the phone into the network?? AHHH yeah after you put PoE routers in…there’s capital…..and then you change the phones out…more capital….AHHHH AM I MISSING SOMETHING HERE???? NO!!)

YOU DON’T SAVE A DIME GOING TO CISCO VOIP from a TDM box for small/medium offices…MAYBE enterprise….MAYBE…but I doubt the ROI is worth it…

And we wonder why America businesses is sucking, especially in the tech area as a former leader…DUH!!!!

Someone please explain why the codec needs to change from G.711u to G.729 simply because of a transition from PRI to SIP?

Does AT&T's SIP service not support G.711? Or are you simply trying to squeeze more channels onto limited bandwidth? (Get more bandwidth.)

The larger you are the more advantages.  For small business I agree sticking with PRI since you can get them dirt cheap.  For example bank with 700 branches can see a 14 month ROI versus fractional PRIs across all those sites, more mpls bandwidth to branch for video/digital signage, fewer hardware costs, etc.

Anyone else have the feeling SIP isn't all it's cracked up to be? In our case, if you're not already getting Internet service from your your SIP provider, it's just not that economical. Especially if you have to keep a PRI around for faxing, modems, alarms, etc.

Yes faxing/modem/postage won’t work. Look into separate device pools for g711 stuff, etc.

We are moving to (ATT) SIP from standard PRI’s, of course we just realized that our unity is G711.

Are there any gotchas by just changing the General Configuration to G729a?
