repercussions of removing ACL 3 from UC560 Vlan90?
had issues with SIP direct transfer of external calls from reception to user voicemail
removed ACL 3 from Vlan90 (CUE vlan)
transfer now works, but what are long term repercussions?
we beleive the deny ip 69.xxx.xxx.xxx 0.0.0.15 any was causing the issue
relevant code below:
interface Vlan90 description $FW_INSIDE$ ip address 10.1.10.2 255.255.255.252 ip access-group 103 in ip nat inside ip virtual-reassembly in
access-list 103 remark auto generated by SDM firewall configuration
##NO_ACES_8## access-list 103 remark SDM_ACL Category=1 access-list 103 permit tcp 10.1.1.0 0.0.0.255 eq 2000 any access-list 103 permit udp 10.1.1.0 0.0.0.255 eq 2000 any access-list 103 deny ip 69.xxx.xxx.xxx 0.0.0.15 any access-list 103 deny ip 184.108.40.206 0.0.0.255 any access-list 103 deny ip 10.1.1.0 0.0.0.255 any access-list 103 deny ip host 255.255.255.255 any access-list 103 deny ip 127.0.0.0 0.255.255.255 any access-list 103 permit ip any any
Re: repercussions of removing ACL 3 from UC560 Vlan90?
Is your call flow as follows:
A calls SIP DID 123456789 >>> Incoming call lands at Reception EXT:100 >>> Receptionist Transfers call direct to EXT:101 VM >>> Transfer does not take place?
Is this the process that is undertaken and where you are experiencing the issues?
Can you please explain to us why there is an ACL on the SIP Providers IP to block access to the CUE? I believe I am failing to understand something here, as I would wonder what would happed if you decided to pluck out a DID from a 100 In-Dial and use that for say Prompt Management or to access your VM remotely, would such an ACL also prevent this from happening???
