[balaji.babu1]

dear all

We are planning to configure the cisco gateway E1 with mgcp protocols, however during srst we have both sip and sccp phone to support survival. I have configure mgcp fallback , sip srst .during srst  everything works as expected ,but when cucm back online it takes 4 or 4 + minutes for normal mode .

I have given  registrar server expires max 600 min 60  in the config ? expecting your inputs.

regards

Both both SCCP and SIP phone delay to register back to CUCM? Name phone models, firmware versions and CME/CUCM versions.

When in SRST mode, phones keep sending keep-alive messages to CUCM. You can use packet-capture or "debug ephone keepalive" (the latter for SCCP phones) to see what is going on with the keepalive messages.

You can look to lower the "SIP Station KeepAlive Interval" timer on CUCM > Service Parameters. This would be for Call Manager service. Do SCCP phones take time as well or is it just SIP phones ?
