Alcatel Unleashed

Hey all

This is the problem
OXE R9.1 and SIP Devices. Both CS on the same network, everything was perfect.

Now CS are on different networks : 192.168.150.1 for the first one and 192.168.151.2 for the second one

The SIP devices registered correctly but incoming calls SIP to OXE are dropped after 5 seconds. Outgoing calls OXE to SIP are OK.
If I go back to the old Netadmin, everything goes back fine.

I use Linphone for SIP devices. I have seen some posts talking about DNS. Can you help more ?

Regards

Remember that only ALU certified devices can handle "spatial redundancy" feature by downloading lanpbx.cfg file and using IP-addresses of CS's.
For 3rd party equipment it's a bit different - they do not support such configuration.

So if you want your 3rd party device or softphone to be connected to whatever CS is active then you need your DNS server configured.
First check TC 1180 - there a reference to a system docs that has a quite good chapters on spatial redundancy and DNS for SIP users.

Hey Alex
OK this I know, but it does not explain why the call drops after 5 seconds
Regards

Hi,
Did you check as said Alex the TC1180 ?
Did you check the dns server ?
How can we help you without traces ?

I had this kind of problem at the customer's . It did help with configuring local DNS server.

Hey Alex

I have set up Name resolver to yes on both Call Server.
I have set up as primary and secondary DNS both addresses of the Main CS on client SIP.

Everything works fine now

Thanks a lotttttttttttt

Bye

Bannaire -

Would you provide some detailed instructions on how you accomplished the solution?
