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

Salman

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

Try doing:

- debug ccsip messages

- debug voip dialpeer

on both ends whilst attempting a call.

Post up the output.

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.

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
