I am installing a Site To Site VPN Tunnel using MX100,MX84 and MS250's. Everything is working perfectly except the Cisco VOIP Phones. Not getting any audio on 4 digit extension calls where the full number has audio and no video at all. Does anyone have
a clue as to what I can do to fix this? QOS configured and Vlan is not shared anywhere else. I am passing the Voice Vlan through
the tunnel.....Could that be screwing things up? Thanks.......Neal Huhn
I assume this is AutoVPN you are using. Are you sure you have included the VoIP VLAN(s) in the VPN list?
Can a notebook on the VoIP VLAN ping the call control systems?
Yes all the VOIP vlans are in the VPN list and the connectivity from end to end is good. The phone registers fine but just
has no video and no ability to 4 digit extension dial.
A Meraki tech did a trace on the phone calls and said the 4 digit dial only showed the 1st digit of the number.
Of course he referred me to Cisco TAC to have the phone system checked. If the phone system wasn't working
properly we would have a lot more that this to worry about. Has to be an issue with Meraki.
Did you try turning off the QOS to test? Also worth looking into whether you have IGMP snooping on/off. May not make a difference but can impact strange things.
We have a Cisco environment and some of our sites traverse Meraki AutoVPN tunnels. Here is our Switch>Switch Settings for IGMP. I'm not sure it'll help but worth trying.
