[Sunish Nair]

Problem: Exactly after 299 sec or 5 min incoming PSTN call getting disconnected.

 details: GW is placed in the Remote location which is configured with H323 and Registered with CUCM which is placed in the Center Office. 

Note: While on the SRST mode call working fine, no calls getting disconnected.

Hi Sunish,

Check the signalling between CUCM and GW. Start looking at below logs

From CUCM
~ CCM SDL and SDI Logs

From Gateway enable below debugs

~ debug voice ccapi inout
