First question: Why the SRST adds the digit "1" before th Cisco SRST is not dependent on Cisco CallManager versions, but phone loads. Cisco, I'd like to see if proper SRST support for Jabber is coming to CUCM and IM&P, or if the community is going to continue to be limited in this area? In its current iteration, Jabber is only SRST capable if an active connection to IM&P remains in place. The Cisco 8200 Series is designed for roles requiring higher scale and external deep buffers. 14. allow-connection sip to h323. bin. If people call in they would get a busy signal. Hi guys.

The SRST failover process occurs faster if there is an active event on the Cisco IP phone device (e. These services are used by a SIP IP phone if a WAN connection outage when the SIP phone is unable to communicate with its primary SIP proxy. If you are looking for increasing / decreasing the time before which the IP Phone falls back to the CUCM from SRST mode, then you need to go under the Device Pool of that IP Phone and set the value (in seconds) for "Connection Monitor Duration":Voice register pool Cisco recommends that you have knowledge of these topics: Cisco IOS® XE feature sets and technology packages; Network connectivity establishment; File copy to Cisco IOS® Smart Licensing basics; Classic Licensing model; Knowledge of how to work CUBE, CME, SRST; Components Used. 6 -> HQ h323 GW -> BR h323 GW BR h323 gateway works fine SRST not working when WAN connectivity to CUCM is terminated?
