<br>
The CUCM version is 6.1.3.1000-16. Is the SIP options ping
parameter available in this version? Where would you enable it
if it is available?<br>
<br>
thanks in Advance,<br>

Hi Dennis,<br>
<br>
Configuring a persistent L2L tunnel proved to be
very elusive. I settled for running a periodic
ping scheduled to keep the tunnel running.<br>
<br>
Thanks for your help<br>

think you answered your own question.
IPSEC tunnel’s take time to bring up.
Maybe you could tweak some of the VPN
negotiating parameters, or create a
separate L2 tunnel profile/group just
for your voice that is permanent and
does not have an inactivity timer.</span></p>

intercluster trunk over IPSec VPN</span></p>

<p class="MsoNormal">Dears,<br>
<br>
I have configured an Inter-Cluster
trunk from CUCM to another site with
CUCME. There is an IPSec L2L VPN
terminating at ASA 5500 firewall on
both ends<br>
<br>
CUCM --->ASA 5540--->Internet
<---ASA 5510<---CUCME<br>
<br>
On the ASA,the IPSec tunnel is
terminated after 30 minute of
inactivity (default) which is
causing a problem. When a phone in
one site tries to call another phone
in the other site there is a
noticeable gap before actual
conversation is heard over the
phone. Once conversation starts,
there is no delay or break in audio.
Has anyone faced this issue?<br>
<br>
best regards,<br>
<br>
Abebe</p>
