Dear Sir
Subject: Cisco ip
phone 9971 registration failed
with CME 8.6 on WAN
I have a WAN simulation with one Cisco2811 router one Cisco1841 router (connected with fast Ethernet interface) plus one layer 2 switch.
I upgraded the 2811 IOS to 15.4M and installed CME8.6, when we tried to add 9971 sip phone If the traffic goes throw LAN (Same subnet- directly from switch to 2811) everything is fine and the SIP phone (9971) added with no problem but when I change the subnet and traffic goes throw WAN
( from 1841 routed to 2811 with default route) my phone didn't register.
It will be great if anybody could help!!
If you can solve my problem, I will be happy to compensate.
