ASA for voice

ahmed — Tue, 12 Mar 2019 06:51:32 GMT

Hi all,

i have cisco ASA which cover CME inside the network, i config IPsec site-to-site VPN, NAT static, also some ACL.

i've allow SIP TCP and UDP but it seem still cannot allow RTP/UDP from outside to inside, the clue was ip phone can call and ringing but

there is no voice, i've check in ASA and found from packet tracer that the UDP packet stop at outside interface in my ASA.

please advice, and if any guide to solve this

Regards,

acer

Hi,

Could you please check if 'SIP' inspection is enabled on ASA. As you are using NATs, you need to use SIP inspection on ASA.
