I have a VG248 with analog phones and few IP phones at a remote site which also as a dedicated Voice Router acting as a SRST router. I presume in the event of SRST kicking in the VG248 needs to register with this voice router. Hence, I try to configure this as SRST Provider but get error as "SCCP: Failed to connect to SRST provider
I would like to understand how does a VG248 function when SRST becomes active. Only find the explanation "During Cisco Unified Communications Manager fallback, Cisco SRST considers the Cisco VG248 to be a group of Cisco Unified IP Phones. Cisco Unified SRST counts each of the 48 ports on the Cisco VG248 as a separate Cisco Unified IP Phone." Would really appreciate if someone could share a detailed document or provide a clearer picture of VG248 in SRST mode.
