[asterisk-users] Choose IAX or SIP trunking?
Asterisk 1.6 behind a firewall and NAT. We are terminating multiple DID calls, originating and transferring. A provider offers both SIP and IAX trunking. Cateris paribus, what is the preferred solution to choose? What points to consider? I can name the provider if this is not against this list policy--is it? Thanks, -kkm

What points to consider?Ceteris paribus, I prefer IAX. It tends to "just work" and it has a lot fewer "knobs" to turn. Some say the audio quality is better with SIP. My experience has been with "low volume" (xx) calls across the internet and "high volume" (xxx) within the same cabinet. I'd try IAX since it is so simple to configure. If you are not satisfied, try SIP. -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards sedwards at sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000

What points to consider?We use IAX trunks from our provider primarily as they are so much easier to configure and you only need one port open on your firewall/nat gateway. SIP needs hundreds, if not thousands of open ports IIUC. HTH Al
We had many problems with IAX2, changing to SIP solved them all. Let me paste link to wise-words which clearly illustrates our experience: http://wiki.kolmisoft.com/index.php/Why_we_do_not_suggest_to_use_IAX2 Regards, Mindaugas Kezys http://www.kolmisoft.com VoIP Billing and Routing Solutions -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Kirill 'Big K' Katsnelson Sent: 2009 m. spalio 1 d. 02:58 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Choose IAX or SIP trunking?
