[Asterisk-Users] Connecting 2 Asterisk using SIP

[Waldo Rubinstein]

I have 2 Asterisk servers running 1.2.0. One of them is a PSTN  
gateway. Currently they are connected using IAX2. I wanted to play  
with SIP.

I setup a sip entry (type=friend) in the PSTN gateway box and a sip  
entry (type=user) in the second box in order to send calls using SIP  
to the second box. This works fine. However, when I setup the second  
box as type=friend in order for it to be able to send calls back to  
the gateway box, then calls no longer work from gateway box to the  
second box. The reported error is:

Dec  5 00:07:14 NOTICE[203]: chan_sip.c:9514 handle_response_invite:  
Failed to authenticate on INVITE to '"2125551212" <sip: 
2125551212 at 10.0.10.1>;tag=as0698b1b9'

In the gateway box, my sip.conf looks like this:

[general]
allowguest=yes
autocreatepeer=no

[secondbox]
type=friend
host=10.0.0.2
secret=mysecret

In the second box, my sip.conf looks like this:

[general]
allowguest=yes
autocreatepeer=no

[secondbox]
type=user
host=10.0.0.1
secret=mysecret

Any ideas on how to correctly set this up?

Thanks,
Waldo
