Hi, I just got my SS7 link up last week, and started stress testing the link. I have SIP --> SS7 on an asterisk server with transcoding. I am using the latest Asterisk 1.2 on a dual Xeon machine: Asterisk 1.2.24 Zaptel 1.2.20.1 Chan_ss7 0.9 Digium TE210P After just 3 days of testing the SS7 link on 1 E1 with an average of 20 concurrent calls on the E1 (Max 25 calls), I have the following warnings: WARNING[27043] l4isup.c: SS7 requester: No idle circuit available. WARNING[27046] l4isup.c: No idle circuit found. The errors started scarce on the second day, and then they increase until they are repeated in almost 3 out of every 4 SS7 call attempts. The problem is that when the error message occurs, only 9 out of the 30 Bchannels are busy, and 21 channels are idle. The only solution to stop these errors and get the SS7 link working again is to restart Asterisk. I have read all the list postings on the subject (only 2 threads are talking about this problem), and there seems to be no solution to this specific bug. All I got is that this is unavoidable in both chan_ss7 and libSS7 under heavy call volumes (suggesting a Zaptel bug). My questions are: How can I avoid this strange behavior? Is there a patch to either chan_ss7 or Zaptel to fix this problem? If I use Sangoma cards instead of Digium will this problem disappear? Your help is much appreciated, Antoine Megalla. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
