Unable to receive calls

[shibukraj]

Hi,

I am facing a strange problem for last couple of days. First all started with failed registrations. It got resolved by itself. Now what I am facing is I can make outbound calls from my SPA 3102. But I am not getting any calls to my SPA 3102. All are going to my VM. Even I tried calling from another voxalot account. After a silience for a minute it goes directly to VM. But when this happens I looked in to the status of the SPA 3102 and it shows registered. The following is the status.
System Status

SPA 3102 is located in INDIA and I do have remote login to the box. Can any one help me in resolving this issue. I have DID's forwared to mu Voxalot account as well. calls to that is also going to VM. Any help is highly appreciated.

Best Regards
