I have a big problem with a gateway (cisco) and ser.
Phone to phone with sip it's ok and when i do phone to pstn the
packets arrive to gateway but the line is busy and the message (when i
made a capture with ethereal ) is -BAD REQUEST Invalid IP.
I don't know what i have to configure. I think the ser.cfg is well
because the packets arrive to the gateway a it reposes.
My quenstions:
- I have to register the gateway
- What i have to do
Thanks

It is unclear from your messages exactly how much work has been
put into the Cisco config at this time. Without knowing anything more
about your config I'd suggest you check to see if the sip-ua and the
appropriate dial-peer statements are defined. You'll want something
similar too...
sip-ua
retry invite 3
retry response 3
retry bye 3
retry cancel 3
timers expires 300000
sip-server dns:<your sip proxy srv name or IP address>
dial-peer voice 10 voip
description Only peer for inbound to SIP Proxy
huntstop
preference 2
destination-pattern 78[1-9]
progress_ind setup enable 3
session protocol sipv2
session target sip-server
dtmf-relay rtp-nte
no vad
!
dial-peer voice 11 pots
description Only peer for outbound 5-digit calls
preference 3
destination-pattern 4....
direct-inward-dial
port 1/0:23
prefix 23
If all else fails debug ccsip messages will give you some feedback
as to what is happening with the call.
good luck - steve

steve,
do you know it is is possible to somehow configure cisco ios gw to use
symmtric signaling, i.e., that it would use 5060 port also as source
port when it sends out a request?

Juha:
I've never looked into that but by default it does not. I thought I would
need "symmtric signaling" in order to define a peer in my Asterisk sip.conf
file but that turned out not to be necessary.

i was asking because of nat detection. it turned out that nathelper
nat_uac_test("3") does not check port number whereas mediaproxy
client_nat_test("3") requires that both ip address and port in via match
source ip address and port. so if call comes from cisco gw, ...
i surfed on cisco's web pages, but could not find any command that would
make gw's signaling symmetric.

Hi all,
I'm quite sure that it does not exist any command on the Cisco gws to enable symmetric
SIP signalling (neither with bind control/media command)....if you issue 'show ip
sockets', you will see that local tx sip port is a random port != 5060...
Regards,
Verbal

Ok. I'll ask around.

Would nat_uac_test("16") help?
From nathelper.c:
2004-09-30 added received
port != via port test (andrei)
/* test if the source port is different from the port in Via */
if ((tests & NAT_UAC_TEST_RPORT) &&
(msg->rcv.src_port!=(msg->via1->port?msg->via1->port:SIP_PORT))
){
return 1;
}
This test only checks if the ports are different. If they are, the other
tests are not run.
AFAIK, nat_uac_test("2) together with nat_uac_test("16") will give you
client_nat_test("3")
(However, I'm not familiar with the mediaproxy code)
g-)

Try:
sip-ua
nat symmetric role passive
nat symmetric check-media-src
Cheers,
