Hi, does anyone here have also problems setting up the asterisk to work with gafachi Virtual Line (GVLine)? I had recently purchased for a virtual line but still my number gets busy when someone is already on the line. Help will be appreciated... Thanks.

I had problems with these guys when I first attempted to setup my account. One of the previous anonymous comments is probably mine.

However, about a year ago I attempted to use the service again and I've been using it ever since. It works great with my Sipura SPA-2100 and the G.711 codecs. The G.729 codec produces horrible call quality for me, but call quality is very good with the G.711's. On occasion there is a slight delay, but that is to be expected with VoIP.

I actually got it working...

...after Gafachi contacted me (a month after my initial technical support request, as I was becoming irate, they finally acknowledged my existence). I found out that I had misunderstood a setting. In my own defense, it was poorly explained on the website, which has virtually no documentation.

The text on the website makes it sound as if IP authentication is a fallback option, in case MD5 is not working. I was trying anything and everything to make the system work, so I provided every available piece of information I could give. I filled in this setting. Here's the actual text of the www.gafachi.com website:

"Configuration on this page applies to Termination (outbound calls) only. By default our network requires calls to be authenticated via MD5. If your equipment/software is incapable of this, and you would like to use IP-based authentication, you can enter your IP Address(es) below."

After which, I was doomed.
Finally tech support wrote me this:

"If you do not have a static IP address, you must remove these IP addresses from our system. If IP-based authentication is setup in our system, this will over ride MD5 authentication. Xten X-lite softphone is capable of authenticating via MD5."

And then the light dawned! Ahhhh.... I am now making phone calls. CHEAP phone calls. Cheap, good quality phone calls.

Thanks!!

I'm making a big guess here, but have you tried changing your SIP register timeout to something smaller, say 900 seconds?

I am using: CounterPath/xten X-Lite SIP Soft Phone, RoadRunner Broadband service, and all the default settings indicated by the /config_xlite example page on Gafachi website. Have paid them my money, so the brand-new account is active with positive balance. I keep getting "Login timed out! Contact Network Admin." error. SIP REGISTER worked, and I can see my computer's IP info reflected on the Gafachi page. I'm stuck in a finger-pointing exercise, where Gafachi says XLite should offer a resolution, and XLite website indicates that this error occurs when an invalid login/password is provided... But I know that the username and password are correct. I think my network service and choice of SIP phone are about as mainstream/popular as any. I have rehashed my settings a hundred times. Aaarrrgh! Does anybody have a working example configuration they could provide me, please?? Advice? Please please please. I have researched, but everything I find doesn't fit. Am I forgetting something fundamental?... like, must I have Asterisk to use my SIP phone? All I want is termination service for outbound calls, no DID, no voicemail, no frills. All help appreciated.

In recent months, Gafachi has announced technical changes that appear consistent with a replacement of their gateways with others not based on Asterisk: IAX support dropped, GSM and iLBC codecs replaced by G.729. This may be the cause of reported improvements in quality: a similar development has been observed for Finarea's services such as VoipStunt, SIPDiscount and VoipBuster.

I have been using gafachi for quite sometime now and have had nothing but perfect quality for both domestic and international calls. Unlike previous providers I have tried, gafachi has not had any outages. I terminate over 500,000 min/month with gafachi and have seen significant savings. I would recommend them to anyone looking for a wholesale provider.

horrible quality

Call quality is unusable.

Good rates, but the call quality I've experienced isn't very good. I would recommend trying someone else.
