OXO PABX SIP Trunk Integration

I have seem similar posts for the codec mismatch but yet they all the post originators claim the codecs are matched ok and no success yet. Hope their is a work around for this.

Hi,

i don´t see NAT for IP 10.66.56.186.
This is the IP that de ISP uses to send trafic to your OXO.
In the NAT config you use 197.248.166.2.
So your Cisco or your ISP are wrong.

Try to use the same IP on both sides
