We have AS5300 H.323 gateway running IOS version 12.3(9). The gateway is used for outgoing calls on a NET-5 ISDN PRI line. We are getting low ASR and the output of the "debug isdn q931" reveals isdn casue 102 (Recovery on Timer Expiry) .The DISCONNECT is always sent by gateway exactly after 10 seconds of SETUP message. I' have tried to tune the T310 timer to 60 seconds but the recovery on timer expiry still appears after 10 seconds.I am trying to find out which Q931 timer value is expired to further debug. Any help would be highly appreciated.
