Asterisk and Freeswitch on the same machine!
Hi friends Since my efforts to find an open source solution for SS7 on freeswitch did not meet any success, we had to resort to a cheap trick! chan_ss7 <-> Asterisk <-> FreeSWITCH where * and FS are on the same machine. Since we wanted to do only 120 calls per machine, it has worked out pretty well. Doing more than 150 calls is meeting a CPU bottleneck (surprisingly from FS side!) One interesting thing, we noted was that FS was taking considerably more CPU cycles than Asterisk (sometimes thrice as much!) when the calls were sent from Asterisk to FS. The dialplan on Asterisk was playing gsm audio (demo context) while FS dialplan was just sleeping! I believe, this is surprising? When doing SIP calls from FS to Asterisk, the CPU loads are comparable. I was under the impression that FS take less CPU cycles? My team member is writing a report with all performance stats, shall share when it is done. Bye, Anita.
1) Sangoma cards with an SS7 stack for FS, a much less hacky solution.. 2) Does your server end up transcoding? Is that why it's using so much cpu? -Avi On Thu, Dec 29, 2011 at 2:40 PM, Anita Hall <anita.hall@simmortel.com>wrote:
