Hello guys, i have encountered a very strange behaviour with my IP Phones:
2 CCMs in mixed mode, all phones registered on the subscriber. 4 GWs with SRST, each one ready for 30 and 40 phones to register.
When i shutdown the publiher, all the phones with SRST references made register/unregister traffic to their respectives SRST GWs. During the publisher down time, the DHCP server was also unavailable.
Is it possible that phones, not able to contact DHCP server (may be for obtaining an ACK for their current IP binds) try to register/unregister on their SRST ref. ???
After unregistering from their GWs, phones register with the publisher without any pb but try again to contact SRST ref a few seconds after.
Does the DHCP server always need to be accessible ?
Thanks a lot for your help
