I can pull up the website for my Cisco 7821 to get the phone number, but I can't find the Line Label anywhere. From my understanding, the label is in the operating configuration, which the phone downloads during the registration process via SCCP/SIP...
I'm sorry if this has already been addressed, but I couldn't find an answer to my question.
I have a pretty standard setup: a few subinterfaces on a router connected to a trunk port on a switch (G0/24). All other ports on the switch have an access...
We set up a new point to point GRE tunnel between R1 and R2 running OSPFv3 and IPv6. This was a second tunnel on R1 that mirrored the other GRE tunnel.
Now, although we were able to ping each other's source interfaces, ping FF02::5 and had PIM nei...
Thank you Rath, but unfortunately, I don't have the rights to access our CUCM - I only administer my section of the network. This is why I was attempting to get that information from the phone or connected switch/router.
Yeah, I think i'll need to recreate the situation and do a packet capture. I know access ports process tagged voice packets, but I didn't think they transmitted tagged packets. I suppose they need to for a Cisco phone to know what vlan is the voice...
No, G0/24 was set only as an access port:
switchport mode access
switchport access vlan 49
switchport voice vlan 48
When I realized the error, I defaulted G0/24 and changed it to:
switchport trunk encapsulation dot1q
switchport mode trunk
G0/24 had a voice vlan and access vlan configured. The registration went through just fine - I was even able to dial out. Unfortunately, I didn't think to collect logs before I changed G0/24 to a trunk port as originally intended.
