[asterisk-users] SIP Trunk with "multiple" remote ip-addresses

[Magnus Benngård]

Hi, 

Did order and setup a SIP trunk to a Swedish ITSP named Tele2. No problem
to get outgoing calls to work but i have some problems with incoming. 

Did set "srvlookup=yes" in sip.conf. "Sending" all outgoing calls to
"sip-corporate.tele2.se" which is either sip-corporate1.tele2.se
(130.244.190.42) or sip-corporate1.tele2.se (130.244.190.46). 

If i do a "sip show peer Tele2", I see that Asterisk has chosen one of
them: ToHost : sip-corporate.tele2.se
 Addr->IP : 130.244.190.46 Port 5060

Now my problems starts, when Tele2 sends a call to my Asterisk, the call
can come frome any of those two ip-adresses. If it comes from
130.244.190.46 everything if fine, but if it comes from 130.244.190.42:
"[Mar 2 08:46:03] NOTICE[1372]: chan_sip.c:19167 handle_request_invite:
Failed to authenticate!" 

I thought "srvlookup=yes" should take care about that, but then i read a
little bit more and found: "Note: Asterisk only uses the first host in SRV
records". :( 

Can anyone plz give me some
hint howto solve my problem? 

Regards, 

Magnus
