Hi Thanh,

my 2c to help you going through this:

- If asterisk keeps re-senging the 200 OK after an ACK was sent to it, you should check whether the ACK was actually delivered, and if delivered whether asterisk logged any error/warning about it. In general, you should provide the SIP traces to get some help.

- You have a typo in your public.xml: 'asteirsk' instead of 'asterisk'. You should check that.

(BTW I'm not sure this is a question for -dev, perhaps -users?)

Regards,
Giacomo

Hi all,

I have configure freeswitch as SBC server with one asterisk server.

I am getting nat issue when make call from FS to FS.

my case as:

client --- FS ----- Asterisk server ----- FS -----client.

my configure in public.xml like:

<extension name="asteirsk">
<condition field="destination_number" expression="(\d+)$" require-nested="true">

<condition field="network_addr" expression="^192\.168\.1\.123$" break="never">
<action application="set" data="hangup_after_bridge=true"/>

<action application="export" data="sip_h_X-ROUTE=LOOKUP"/>
<action application="set" data="bypass_media=true"/>

<action application="bridge" data="user/${destination_number}@${domain_name}"/>
<anti-action application="set" data="hangup_after_bridge=true"/>

<anti-action application="export" data="sip_h_X-ROUTE=LOOKUP"/>
<anti-action application="set" data="bypass_media=true"/>

<anti-action application="bridge" data="sofia/internal/${destination_number}@192.168.1.123"/>

</condition>
</condition>
</extension>

Call is process ok, But I see that when I answer call in destination, asterisk server alway send 200OK to my FS, FS return ACk, but asterisk resend 200OK.

if any one can help, thank all alot. I am getting this stage to long and cant find any solution here.

Thanks,

ThanhTruong
