[asterisk-users] switching from SIP to Skype..or not
Hey all We have been working with SIP for years. It has the potential to be better than Skype. It is really all in the implementation. Not all SIP soft clients are equal nor are the networks and computers they are running on. I will not bash Skype. We have tested it and in most cases choose not to use it. It has it's place and is good for the user that meets it's specific target demographic. SIP is a sold communications protocol that can communication with codecs of differ audio and video quality levels, and supports industry standard software and hardware endpoints. With SIP you get to choose how good your quality is. With Skype Microsoft does. It comes down to what do you want to achieve, how much resource do you want to put in to it, and are you committed to a bit more work for a lot more options and better quality, or do you want a quick and easy solution with differing limits. Both solutions have their place. To me SIP vs Skype is like complaining apples and carrots do you want fruit or veggies you get to choose. You can choose to agree or disagree with my statements. I hope they are useful to some.

I don't actually know it's a sound quality issue, per say. It's double+ NAT, with a wi-fi bridge, plus, sometimes, another wi-fi network. In that situation, skype works from a cell phone! Granted, there are dropped calls, but, eh. The way things stand, I can't, unfortunately, use Ekiga to connect to the **outside** SIP provider because, apparently, there are too many hops: http://superuser.com/questions/880705/ IAX might be useful in this circumstance :) -Thufir

Sorry for the empty message. Pressed the wrong button. I have been wrestling with a pretty generic Asterisk configuration (version 11.11.0 ) set up with FreePBX. The trunk SIP is setup to allow ulaw,alaw,gsm, Video is disabled. I was using Eyebeam and am now trying Jitsi. Jitsi has a number of codecs enabled - opus, SILK, G722, speex,PCMU, PCMA, iLBC, GSM, G723 and telephone-event The internet connection from the workstation to my internet supplier (workstation to firewall/router to speed test server at ISP) tests at 13MBs incoming 6Mbs outgoing. The problem has always been great sound from the other telephone and choppy sound (dropped sound fragments) from me to the caller with only one call going through Asterisk and the network pretty much dedicated to the my workstation. This has survived upgrades of everything (firewall, Asterisk server, workstation) This has reduced my Asterisk telephone to an answering machine with Skype as my way of actually talking to people. This fixes the sound issues and is actually cheaper since I pay a low monthly fixed cost for Skype access to all North American telephones. Skype does not seem to have an problem traversing the same network even with two way video active or during multi-party conferences (mix of Skype and telephones in the group). I would like to have a reliable 2 way conversation using Asterisk but have not found any suggestions about the source of the problem or how to fix it.
