[Frederico Madeira]

Hi guys,

I configure one Fedora Core Linux 5 for use with asterisk as gateway
using Digium TE110P interconected in Alcantel 4100
I've set up it to register 100 voip numbers on my provider.
All calls on Alcatel is send to asterisk.

In some periods of day i receive this messages on asterisk console:

Dec 12 17:49:30 NOTICE[11565]: chan_sip.c:11564 sip_poke_noanswer:
Peer 'provider-13052181000' is now UNREACHABLE!  Last qualify: 0

Peer 'provider-13052181002' is now UNREACHABLE!  Last qualify: 0

In all 100 numbers.
I already change the link, but the problem still happpen.

I use in sip.conf have this configuration to register lines on provider:
register=>13052181000:1221212 at sip.provider.com/13052181000
register=>13052181001:1221212 at sip.provider.com/13052181001
register=>13052181002:1221212 at sip.provider.com/13052181002
.
.
.

[provider-13052181000]
type=friend
context=default
secret=1221212
username=13052181000

[provider-13052181002]
type=friend

secret=1221212
username=13052181002
host=sip.provider.com
fromuser=13052181002
fromdomain=sip.provider.com
nat=yes
insecure=very
canreinvite=no
qualify=yes

If i disable 30 lines and restartr asterisk all lines are register normaly.

So, Have any limit in network stack or in asterisk ? Have any tunning
that can i make on linux or in asterisk to resolve this question ?

Thanks.
