Hi I have a FreeSWITCH installation, doing outbound telephony, with a peak load of about 500 to 600 concurrent channels. Now I have to do a similar setup in a market where SIP telephony is not available, so it has to be ISDN. I am looking at buying either Digium or Sangoma cards. Does anyone have any experiences about reliability of these cards? How does the cpu load per channel compare to SIP telephony? -- Tor Petterson tpe@actimizer.com Tobaksvejen 25, 2. tv. - 2860 Søborg Telephone: +45 39 55 05 32 www.actimizer.com
Nowadays the whole Digium vs. Sangoma thing has boiled down to preference more than anything else. They are both pretty reliable (I've used both) so I wouldn't use that metric as a tie-breaker. If money is the ultimate deciding factor then a Digium clone is probably the cheapest. However, if you want to support the company who has supported the FreeSWITCH community the most then it's hands down Sangoma. Also, we know all the Sangoma guys personally (Hi Moy!) and they have produced the bulk of mod_freetdm. Buying Sangoma is a great way to support FreeSWITCH. Just my opinion, but I hope it's good food for thought. -MC On Thu, Aug 23, 2012 at 1:42 AM, Tor Petterson <tpe@actimizer.com> wrote:

Just to complement Michael's accurate description of the situation (Hi Michael!) ... There is a few other differences, such as the fact that if you ever need SS7, there is no SS7 stack into FreeSWITCH for Digium boards, just for Sangoma (due to SS7 stack restrictions). For ISDN, although I know a few people using libpri in FreeTDM, the Sangoma SS7 stack in FreeSWITCH (ftmod_sangoma_isdn) it is the one more actively developed and under continuous improvement and professionally supported (not just community support). If you go with Digium cards you have to stick with the libpri module pretty much and the community support. All in all, my guess (although probably biased) is that most FreeSWITCH users use Sangoma cards and therefore if you run into issues you are more likely to get help (either via community or via Sangoma support) if you use a Sangoma card.
