[Asterisk-Users] voip to voip bridge
Has anyone had any good experiences with a voip to voip bridge... where you have an incoming call on a voip line which is redirected out another voip line to a regular phone line? Whenever we do this, the connected call is kinda lagged and the quality isn't always that great. It seems to me this is just a problem with the inherent delay in the voip connections. But I was wondering if there's any special configurations that could make the situation better?

Re: [Asterisk-Users] Re: GXP-2000 (steer clear)
So far, pretty much every firmware upgrade has been an improvement in one way or another. They're running 1.1.0.13 now which seems to be fairly stable. They still get brief moments of echo, but usually only when the handset volume is up pretty high. I think it'sa hardware problem where the handset microphone is actually picking up the handset speaker audio when it gets real loud. If you do get these phones, I would make it very clear to your customers that this is a very inexpensive phone, aka CHEAP. So don't be surprised if you have some problems every once in a while. But they do have some great features that you only find in more expensive phones and some features even the big boys don't have. They especially work well remotely, extremely nat friendly... which I cannot say for the Cisco's or Polycom's.

What bothers me the most is that the phone stops working often (multiple times per day). By this I mean that my client won't be able to dial anything successfully. As soon as 3 or 4 digits are entered, they get a fast busy. To solve it, they need to reboot it. It sounds as if these phones were running Windows instead of Linux :) Anyway, what firmware did you use that solved so many of your problems?I've only had bad experiences with these phones and steer clear of them. In the same price range you can now get the Thomson ST-2030 or Polycom430 for a much, much better user experience.___--Bandwidth and Colocation provided by Easynews.com --Asterisk-Users mailing listTo UNSUBSCRIBE or update options visit:http://lists.digium.com/mailman/listinfo/asterisk-users ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] GXP-2000
We had not used these phones before, which I will admit was my first mistake. However, I did do research online to see what other peoples experiences were but the major problems with the phone started surfacing onlinealmost immediately after we installed them. Before that, there were the usual like them/don't like them posts. But there was nothing about the multitude of problems, serious problems. The only issue that I knew about when we got them was the speakerphone problemwhich required a (beta) firmwareupgrade to resolve, didn't know it was beta until after we got them. In fact their firmware is still stored in a BETATEST folder to this day... which really gives me a warm fuzzy feeling.

Re: [Asterisk-Users] GXP-2000
We setup a company with 50 of these phones and had my client not been as understanding as they were, that could have put me out of business. What an unbelievable nightmare. This was about 8 months ago when the firmware was so bad the phone was a better paper weight than anything else. Since then, they've fixed a lot of problems and made a lot of the features work like they're supposed to. But we still have issues with them quite frequently. From phones that need to be rebooted occationally, to ones that just drop calls, or do nothing when you pickup the receiver... lots of little qwerks. We even experience their poor grounding problem every once in a while when you get a small static shock from the phonewhich cases it to reboot.I don't think there's any firmware that can fix that. We had to get several phones RMA'd because they just plain died. The worst ongoing issue has been the echo andthe really crappy speakerphone. The customer is pretty much used to it now. But we're slowly replacing them with Polycom's as new people come on and as others just get fed up.Unfortunately one of the phones met it's doomby wayof a hammer.But I guess, what do you expect for under a hundred bucks.

Re: [Asterisk-Users] Echo cancellation
Asterisk performs echo cancellation for all incoming and outgoing calls through the T1/PRI card. However, there are some things that canstill cause echo's. We had a similar situation a with a setup much like yours. We switched to the MG2 echo canceller which helped quite a bit. But finally, after testing everything else we possibly could, swapping out PRI cards, changing every concevable setting related to echo, and having the phone company out about a dozen times to check the PRI, we ended up switching companies from Telepacific to Sprint and the echo problem, according to the users, completely went away. However, a couple things you may want to look at is the audio gain settings in your zapata.conf and make sure they're not set too high, maybe even try dropping them down a bit. And try the MG2 echo canceller if you haven't already, it seems to provide the best results on PRI's, at least as far as our testing has gone.

Re: [Asterisk-Users] Stay away from Grandstream!
We have 50 Grandstream's that we purchased about 3 months ago. They're all at one site and we've had nothing but trouble with all the phones. The echo is the worst problem of all. We had to upgrade from the default 1.0.1.9 firmware to the 1.0.1.12 betato get the speakerphone to work properly. Once we did that, there is now abad echo if one of the GXP users turns their volume up too high, the other party can hearan echo. If the GXPuser turns their volume down a bit, the echo starts to go away. This happens internally from GXP to GXP as well as with outside callers. At first Grandstream didn't want to admit that they knew about this or that they'd even ever heard of this problem before. But they finally at least said they would have an engineer check into it. Then after some research onlineI come to find that lots of people are having the echo issue with the newer firmware and they had also notified Grandstream months ago. So they know about the problem. On top of the echo issue, which is completely unacceptable, we've had a couple phones flat out die, we've had several that had the PoE go dead so we were forced to use the AC adapter. And many of the other phones suffer from all kinds of stupid little intermittent issues such as dropped calls,rebootsand strange ticking and static on the line, even on internal calls. We discovered that quite a few of the network cables that came with the phones seemed to be faulty, which when replacing them seemed to solvesome of our dropped calls and spontaneous reboot problems. Some of the phones hadbad handset cables. Replacing some of those seemed to get rid of some of the static issues. We've replaced several of the really troublesome phones with Cisco's or Polycom's, and what do you know, no problems whatsoever. All in all, we have been extremely disappointed in the reliability of the phones and especially unhappy with the level of service from Grandstream. Grandstream should not be permitted to sell these phones to consumers, marketed as a business class phone of all things! They're knowingly selling a faulty product.It's outrageous. And what's even more amazing is they claim that the GXP2000 won some sort of award, and it's even a Best Seller at Atacomm.com. How it the world can that be. The phone is a piece of crap. They're either going to fix these problems once and for all or give us our money back.

Re: [Asterisk-Users] Grandstream GXP-2000
It does appear to be the remote party that is hearing the echo as a result of the loud volume on the other end. They actually had a few people calling in from the outside report that they could hear their echo. When they turned down the volume on the Grandstream, the echo seemed to go away. So I will bring up the possibility of using the AEC when using the handset.

We currently have 3 sites with about 15 GXP-2000s at 2, and 3 at the third.The 2 larger sites are running 1.0.1.9, the third site is running 1.0.1.12. On straight SIP-SIP calls or outbound calls via an IAX-PSTN gateway, thereis no discernable echo at all. Ever.One of the larger sites is connected with 2 BRIs for incoming calls viazaphfc. Generally, there is echo for the first 2 or 3 seconds of a call, then it dies out completely. There are exceptions - I've had reports of echolasting for the duration of a phone call, but this has usually been down toa callcentre at the other end of the line (probably using an autodialler) where the first few seconds of an inbound call is silence. I guess this mustbe upsetting the echo training in Zaptel.The other larger site is connected using a TDM400 with 3 POTS lines. Thereis nearly always echo on incoming calls on these lines for about 30 seconds, after which they appear to be fine.In conclusion - I'm not sure if the GXP2000s are the problem in yourscenario.Regards,Chris--C.M.

[Asterisk-Users] Grandstream GXP-2000
We're having a rather serious echo problemusing the Grandstream GXP-2000's with Asterisk 1.0.9. I'm wondering if there is something I'm overlooking that might be an easy fix. The echo seems to be worst on internal SIP to SIP calls but you do get it every once in a while on outgoing calls through the PRI. It's not the speakerphone echo problem, we're running the 1.0.1.12 firmware that pretty much fixes that. It seems like most of the echo cancellation functions are for outgoing calls through the phone company. Is this a more likely a phone problem? We've got about 50 of these phones all doing the same thing. -- | Erick Baum ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
