iax2 or sipp soft phone

[Gambit]

Hi

I recently installed asterisk onto a kubuntu box and was wondering what is the best windows softphone to use. Also should we use an iax2 based phone or a sipp based phone and what are the advantages of each type. So far I've tried idefisk which seems to be cool but it's seems to be lacking conference call functionality.

Thanks

SIP/IAX: firefly (free)
SIP: Xten family (Xlite free, Xten-Pro, Eyebeam not free)
SJphone (free for 5 licenses)

pls google them to find the downloads and try which one is your favorite

PS, you had Asterisk, why using softphone's conference function? Dial 8xxx (xxx is your extenion) from your phone, you can set up a conference room on Asterisk, other partcipants dial same number can join the conference

I use XTEN Sip .. works a treat.. for hardware, I use the Cisco Handsets. My asterisk system connects to Sipgate.de and Sipgate.co.uk ... its awesome, you can phone my landline number in the UK and Germany and it all comes back to me here in SA :-)

Hi,

I am currently living in London. I have a few servers colocated at work (bonus working for an isp
I run Asterisk with a sip trunk into sipgate.co.uk too. Softphone at work and a Cisco handset at home as extensions on the pbx.
I want to get friends and family in Cape Town to use Xlite to call me via the Asterisk box.

Only thing is round trip times are 450-500ms from the PBX to the SA clients (ADSL) and I was wondering if it would be worth it as that is a fairly poor round trip.

I had an idea to run Asterisk on a friends' box in Cape Town
@ datapro.co.za which, as far as I can tell has the lowest round trip time to my London boxes [160ms] (we are on the Level(3) backbone with tertiary AboveNet links) This setup hopefully cutting out Telkom/Other ADSL providers' connections to the UK via the US (and thus shaving off a good few hundred milliseconds!)

So I'm interested, is your setup really *useable* ie: is the quality good enough that you dont get drop outs and really bad delays?

Guess one might be able to terminate a POTS line into the Asterisk box at the Cape Town end for a proper setup to get out to the SA PSTN. Which brings me to my next question, are there any SA companies offering what sipgate do?

Thanks for any input you may have!

Regards,
Andy.

I use it on a iBurst line.. works perfectly, no lag what-so-ever. You have to keep in mind how SIP works. The asterisk is the "Broker" for the link, voice data is sent directly to the people talking to each other. I love it :-)
Yes, a terminating point in cape town will make it easier to land calls, just dont tell telskum There are no companies offering what sipgate does... if there are, I cant find them.
