Hi everybody,
I set up a CUCM 9.1 machine to work on ipv6. Problem is, if I try to register any SIP ipv6 enabled device (Polycom IP phone, Phoner Lite softphone), I'm getting "Destination unreacheable (port unreachable)".
Registration works fine when using ipv4.
I run through the check list from here: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/trouble/8_0_1/tbfeat.html#wp1166459 and everything is configured as requested.
Is it possible that CUCM uses a different port than 5060 for SIP on ipv6?
Any idea what could be wrong here?
Thanx
