> | I just got my SS7 link up last week, and started

> | I have SIP --> SS7 on an asterisk server with

> |
> | I am using the latest Asterisk 1.2 on a dual Xeon

> | 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.

> |
> | 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
