brekeke re-transmit INVITE after getting 180 and 200

breque · Post by **breque** » Wed Aug 10, 2011 9:53 am

1. Brekeke Product Name and version:
2.4.8.6
2. Java version:
1.6.0_18
3. OS type and the version:
Linux debian 6
4. UA (phone), gateway or other hardware/software involved:
PBX and xlite
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
pattern 9
6. Your problem:
A is calling B
INVITE from A to Brekeke SIP Server.
Brekeke SIP Server forward the INVITE to PBX.
PBX return INVITE to Brekeke SIP Server.
Brekeke SIP Server send INVITE to B.
B reply with 180 and later with 200, however, Brekeke SIP Server is doesn't stop sending INVITE.
notes - doing the call without going to the PBX is ok, but I must have the PBX because it has all the contacts.
I have a wireshark trace if needed.

looking forward for your help.

what kind of PBX are you using? Which product is it?

breque · Post by **breque** » Thu Aug 11, 2011 1:09 am

asterisk

forgot to mention the most strange thing.
the BSS sends back the 180 and the 200 correctly to the A party.
anyone encountered that behavior?

Does A keep sending INVITE too?
Does Asterisk keep sending INVITE too?
Does Asterisk change Call-ID?

A doesn't send any more INVITE
Asterisk doesn't either.
call-id remains the same as the asterisk is configured to work as proxy.
it's like the BSS doesn't recognized that the responses belong to the INVITE but if it didn't, why did it sends back the 180 and 200 to A?

Let you use the B2B-UA mode in Brekeke SIP Server.

Its setting is [Configuration]->[SIP]->[SIP exchanger]->[B2B-UA mode].
It will avoid the problem.

already tried it.
didn't help.
tried changing pretty much every configuration in the configuration page.
thought it might be my DP but I am using a simple one that is even shown in the documents.
it MUST be something very simple and obvious I am (sadly) missing.

A 180 response sent back from B must have same Via, Call-D, From and To headers.
Can you check them?

If you need.. you can contact brekeke's reseller or support team to request some assistances.

I can't find any clues from the packets.

Why do you need to send INVITE back from Asterisk to SIP Server?
Can you send INVITE directly from Asterisk to B??

Furthermore.. why do you need Asterisk ???

breque · Post by **breque** » Mon Aug 15, 2011 11:43 am

I am using the BSS NAT capabilities but everything is located on the asterisk.
I am surprised I am the only one facing this issue.
Seems to be very simple layout I am using.

Will appreciate any suggestion.

Thanks

Are you sure that the Brekeke SIP Server keep sending INVITE to B?

If you capture packets between Brekeke SIP Server and Asterisk, does Asterisk resend INVITE to Brekeke SIP Server?

breque · Post by **breque** » Mon Aug 15, 2011 11:55 am

yep. asterisk send only one.
bss kerp sending.
got many traces

Is B X-Lite?
Is B behind NAT?

Even if you use B on a public IP (not behind NAT), does the problem happen ?

breque · Post by **breque** » Mon Aug 15, 2011 9:55 pm

B is Xlite and is behind NAT.
didn't try with public IP yet

janP · Post by **janP** » Tue Aug 16, 2011 12:57 am

Let you try it.
Using XLite on a public IP may make a different result.
