Hi Saravanan,
thanks for the gret info. I would have a question regarding the overhead on the controller processor when using unicast mode.
When would be actually optimal to switch to multicast mode? How many APs would be needed to reach that overhead? How many clients? Any raw guidelines?
Thanks.

Hi all, is it possible to setup a site to site vpn in the following scenario? VPN-Router-1 ----- ASA (PAT) ----- VPN-Router-2 the ASA has a fixed IP and another IP range which is routed to it. would it be possible to build the vpn to the range that is routed to the ASA? it would be like this: ASA - 1.1.1.1 - static, configured on the outside interface. - 2.2.2.0/24 - range used for NATs/PAT, etc., routed to the ASA - would it work if the vpn will be forwarded from this range to the inside IP of VPN-Router-1? (static one-to-one NAT) Thanks. Regards

where exactly? I know this post but it's nothing related to this issue. I've tested the same config with asterisk and it works. Thanks.

it doesn't really connect, it rings and when I answer the call gets terminated on the sip client side but the cisco phone stays "connected", as if it is connected. on webrtc console I got this, which is a bit strange because I only enbaled g711. so I believe something's wrong on webrtc side when I call from cisco -> sip. ***ERROR: function: "tdav_session_audio_start()" file: "src/audio/tdav_session_audio.c" line: "389" MSG: No codec matched ***ERROR: function: "tmedia_session_mgr_start()" file: "src/tmedia_session.c" line: "873" MSG: Failed to start audio session sip -> cisco, there's no message played, the call gets "declined" with SIP/2.0 401 Unauthorized. Thanks.

Hi Chris, thanks for the reply. well the devices are sipml5/html5 sip clients. I'm trying the webrtc with the CM in my lab to see how it works. The problem is that when I call from a sip client to a phone registered on the CM I've got: SIP/2.0 401 Unauthorized, so the call fails. I thought this might be due to the fact that the CM doesn't know the source IP of the INVITE. CM has no sip trunks. If I set up a trunk on the CM to the webrtc gateway, then the sip clients try to register over the trunk and then I've got: RECV:SIP/2.0 405 Method Not Allowed Warning: 399 cucm "SIP trunk disallows REGISTER" Any ideas? Do you have any experience with webrtc? Thanks.

Hi guys, would it be possible to allow sip users to register over the sip trunk on the Call Manager? or is this method not allowed? Thanks. Best regards

Hi Marius thanks for the reply, I mean the overall flash. for ex the ASA5500 needs 512MB: http://www.cisco.com/en/US/docs/security/vpn_client/anyconnect/anyconnect31/release/notes/anyconnect31rn.html#wp44010 The minimum flash memory recommended for all ASA 5500 models using AnyConnect 3.1 is 512MB but there's no info regarding the flash for routers. Does anybody know this? Thanks.
