I agree with you and I would have done the same. <br><br>Here is the logic behind the current configuration.<br><br>1. The site is in India and the main site is in US . We do not need local PSTN access in India as this an extension of the main site.<br>
2. We do have IPSEC as backup but it still drops the call as it takes some time for the IPSEC link to become active and how would you tell the IP Phone to route voice traffic to a secondary link.<br><br>Thanks,<br>Aman<br>

This begs the question, even *if* the call *were* able to be maintained during a link flap would users even tolerate conversations that sound like trash or intelligible? The more reliable solution to this would be to install a two or four port FXO card for use during SRST. Having a single point of failure for your remote office be the data link between the central location and the CCM is usually not a good idea. I understand you might have this setup for billing/monitoring reasons or whatever but the difference between a few calls going out a few CO trunks and having no telephone communciations is a pretty big deal.<br>

I have a remote location which registers to the CCM at the central site , all the PSTN traffic exits out of the central site gateway and we do not have any PSTN link at this remote site. This site is an extension of my central site. I have situation here as the my data link to this site flaps for 10 seconds resulting in all active calls to drop.<br>
<br>
I am using CCM 6 at the central site. Is there any way I can keep the call up when the link flaps. I know the call survives only when IP Phone losses it's link with CCM but in my case the entire data link goes down.<br>
<br>
I know it is not possible as the entire data link goes down but out of curiosity want to know if this is remotely possible.<br>
<br>
TIA,<br>
