Mobicents SS7 Connection Breaking Down

[FOMI]

Dears

   I'm using Mobicents SS7 1.0 Final connected to Ericsson GMSC and I'm having the following problem, after some period the connection break down and Mobicents tries do recovery it, but get the message "java.net.BindException: Cannot assign requested address".

 It seams the Mobicents break the connetion after receive a request from GMSC, can the group help on this?

Are you using multihome for SCTP and SCTP socket is bound to multiple address?

Amit.

[FOMI]

Yes, it is.

[FOMI]

Yes, it is.

     I saw there is some updates in the SVN that support connectios for multi-home avoiding IOExecption, do you have a configuration example for this new feature like Mobicents_SS7Stack_User_Guide.pdf?

This is known issue 

http://code.google.com/p/jss7/issues/detail?id=53

Its fixed now in trunk. Can you use Mobicents jSS7 from git master barnch http://code.google.com/p/jss7/source/checkout ?

Amit.

[FOMI]

Ok, but there is some configuration example for the
Mtp3UserPart_m3ua.xml and SCTPManagement_sctp.xml , using multi-home?

Regarding M3UA nothing would change for multi-home as its transparent to M3UA.

Regarding sctp see below example

<?xml version="1.0" encoding="UTF-8" ?>

<servers/>

<associations>

<name value="PHHLR1SctpAssoc"/>

<association name="PHHLR1SctpAssoc" assoctype="CLIENT" hostAddress="10.199.118.38" hostPort="2913" peerAddress="10.225.116.2" peerPort="2905" serverName="" ipChannelType="0" extraHostAddresseSize="1">

<extraHostAddress value="10.199.122.38"/>

</association>

</associations>
