similar to: Sangoma on Telstra E1 Tx/Rx and Echo Settings

Hello, We have an Asterisk 1.0.9 machine with a Sangoma A101 card fitted, it is connected to a Telstra OnRamp E1 in Melbourne, Australia. The problem we are experiencing is extreme echo and clicking noises. These are only audible to the calling party, e.g. the person calling in from the PSTN to Asterisk via the E1, the person on the SIP handset cannot hear any echo or clicking, only the

We just installed a box into a Melbourne site with a Sangoma A101U, it is running the latest Wanpipe drivers and has Asterisk on it that someone had compiled manually from source. This initially worked fine but for the sake of consitancy we removed the existing asterisk and used emerge to install it. During this time the box was off of the e1 for about 8 hours and when it was brought back

Hey Guys! We had echo issue before so we replaced old PRI card with Sangoma A102D HWEC. Now my question is i set rx/txgain level 0.0 default do i need to touch this value or default is best. I have read on google and people say it should around 14844 on ztmonitor for rx/tx level same. I just use milliwatt and test my default 0.0 rx/tx level and it come around 4600. Do you think i need to make

Hi, now that these cards have approval in Australia, has anyone had any luck in connecting them to a Telstra Onramp 10 service? Are these configured as a PRI, bchan=1-10, dchan=16 in zaptel.conf and switchtype=euroisdn in zapata.conf? Better yet anyone have any of the above .conf files they could share? Is an onramp 10 what is referred to as a 'channel bank'? Craig

Hi folks, just a quick update.... we managed to solve our problem by getting telstra to turn of the STD pips on outbound calls. We don't the effect yet on inbound (but we haven't had problems in the past) as most of our lines with x100p's are generally only used for outboung. Gary .

I've installed a TDM400. Having a go with AMP. I would like incoming calls to be put throuhg to an extension (at my desk) and a mobile (cell phone) at the same time. Whichever picks up, gets the call.. This should be possible with AMP (call groups, 200|201|0*0408xxxxxx), but it didn't work, so I have created a custom-incoming in extensions-custom.conf What is happening is, The extension

I am having problems getting incoming caller id to work on a Telstra Onramp 10. I have changed "/DEFAULT_CIDRINGS 2"/ Is there something i'm missing ?

Hi, I am still struggling with the E1 card!!!! Does anyone has some experience with sangoma E1 card? I have this card in soekris net 4801. First I was runnig it with deactivated DMA and I was receiving overruns (even with no channels in use). Then I enabled the DMA. Now I have the overruns only during a call. When I'm using more than one channel, the voice is stuttering and the delay is very

Hi, sorry for the newbie hardware questions but here it goes scenario - our telco is feeding us e1 thru coax connection (unbalanced) - so the coax feed rx-tx goes to our old pabx using ericsson bp250 - what we wanted to do is to install asterisk in between hence telco<-->asterisk<-->bp250 using asterisk to power up the voip portion the problem is the we are getting crackling sound

Shortly, I'll be purchasing a Sangoma A102. I'm wondering if I should spring for the hardware echo cancellation circuit or not. Upon initial implementation, the 2 T1 Ports will be used as a passthrough as we slowly transition off of a legacy PBX. Eventually, we'll only be using one of the ports, and will be providing VoIP service to a bunch of SIP deskphones. So - with that usage

Hi, Has anyone ever experienced crosstalk with sangoma analogue cards on 64bit? We have exhausted every test to try and replicate this and find a solution with Sangoma tech support, but we can not fix it. We are about to try the card and four *seperate* UK BT lines in a 32bit system. The current system is a 4gb, dual core cpu with pbx in a flash 1.4, Zaptel and Asterisk 1.4.21-2 Currently we

Hi, Just wondering if there are any people out there using the Zaptel Wildcard E1 interfaces on Telstra PRI?s in Australia. If so, is anyone happy to share their config?

I'm a long time user of Digium carts and stupid me i wanted to give Sangoma a try. We got Sangoma A400 with 6 FXO ports. Asterisk version: 1.4.35 Zaptel version: 1.4.11 Wanpipe version: 3.5.11 we tried to use fxtune but looks like it wont work with Sangoma card, ( please correct me if i'm wrong) Echo is really bad and also we have background noise on all lines. We tried both mg2 and

I think you are absolutely right. The audio I heard earlier sounds exactly like a timing issue. So: wanpipe1.conf: TE_CLOCK = NORMAL TE_REF_CLOCK = 0 wanpipe2.conf: TE_CLOCK = MASTER TE_REF_CLOCK = 1 zaptel.conf: span=1,1,0,esf,b8zs span=2,0,0,esf,b8zs I'm going to make this change and reload at lunchtime, I'll document it and post it to the list if it works.

Followup on this issue, it appears that using a single PRI's clock as the master clock avoids clock drift between the PRI's and we get no more artifacts. So, : wanpipe1.conf: TE_CLOCK = NORMAL TE_REF_CLOCK = 0 wanpipe2.conf: TE_CLOCK = MASTER TE_REF_CLOCK = 1 zaptel.conf: span=1,1,0,esf,b8zs span=2,0,0,esf,b8zs -----Original Message----- From: Michael L.

Aha, it just happened to me, so now I can characterize the audio: It basically sounds like it's missing every other sample - fuzzy and distorted. Timing?
