HI all
Following is my scenario....
------------------------------SIP------------------------------
Router (CCME)--------------------------------Internet cloud--------------------------------Router(CCME)
IP=203.99.xxx.x IP=203.190.xxx.x
i want to setup SIP trunk between my two sites with real IP, i donot create any GRE or IPsec i want to creat simply SIP trunk without tunneling.
Question is this possible or not ?
Regards

Sure - as long as the two routers have IP reachability to each other.
Just create a dial-peer pointed at the far end IP and specify 'session protocol sipv2' and appropriate destination-patterns.
If they are exposed on the internet you should protect them appropriately to avoid people trying to hack your SIP service.

Aaron i am using 2800 series routers with on both end with following IOS ,,,,, buts its not working i read that IOS 15.1 in fraud prtection block all incoming session we need to enable it but its in the 15.1 not in my case m i correct ? following is the configuration also ......
Site A:
dial-peer voice 200001 voip
description **Incoming Call from SIP Trunk**
voice-class codec 11
session protocol sipv2
session target ipv4:62.x.x.x
incoming called-number .
dtmf-relay sip-notify
!
dial-peer voice 200002 voip
destination-pattern 31..
voice-class codec 11
session protocol sipv2
session target ipv4:62.x.x.x
dtmf-relay sip-notify
Site B
dial-peer voice 2000000 voip
destination-pattern 27..
voice-class codec 11
session protocol sipv2
session target ipv4:83.x.x.x dtmf-relay sip-notify
dial-peer voice 30 voip
description **Incoming Call from SIP Trunk**
voice-class codec 11
session protocol sipv2
session target ipv4:83.x.x.x
incoming called-number .
dtmf-relay sip-notify
****The above incoming dial peer is shared between this and another SIP trunk those other SIP trunks using GRE with call manager******
Site A: c2800nm-advipservicesk9-mz.124-22.T.bin
Site B: c2800nm-advipservicesk9-mz.124-22.T_2.bin
What you thinks what is the problem

Try doing:
- debug ccsip messages
- debug voip dialpeer
on both ends whilst attempting a call.
Post up the output.

Hi Aaron
check below the debug output the strange thing is when i call to site B from site A, site B donot show any logs during the call i donot know why although i can ping the real IP's but still its not working and not even showing the debug output...following is call from Site B (ext no 3110) to Site A (ext no 2700)

Hi
It tries to send it three times as it doesn't get a response from the far end.
As you have said the far end does not receive the message, there must be something blocking UDP 5060 between the two routers.

Thanks for replying aaron can you do me a favour and let me know that how from these debugs you came to know that its trying three times but no response can you please highlight that area on my give debug outputs.......
and i will check either 5060 is open from our network and from provider or not........but i personally think 5060 is working but let me double check..... and meanwhile please do me favour and tell me how you cam to know about this ....
Thanks again and really appreciated

Hi
Well... now I look again, I see just two!
But the point still stands... there are two lines in your debug where is says:
Sent:
INVITE sip:2700@Site A real IP:5060 SIP/2.0
Each of those marks a new SIP INVITE, and if you look at the content they are identical except for the timestamps which are about a second apart.
As it is UDP there is no three-way handshake so the router just keeps trying to send the INVITE again until it gives up.
If you have only opened the TCP port 5060 between the routers you should switch it to SIP:
conf t
voice service voip
sip
session transport tcp
end
