<p class="MsoNormal"><o:p> </o:p></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<o:p></o:p></p>
