Hi Everyone
I currently have a h323 gateway which is connected to PSTN via a PRI.
because of cost savings , we are canceling the PRIs and getting a SIP trunk.
how do i go about configuring the SIP trunk into the IOS to conenct to PSTN?
anyone has any sample configs that i can take a look at?
for the H323 and PRI, i always have the Serial interface with the ESF and B8ZS and so on.
how do i go about configuring the SIP for PSTN access?
any help is greatly appricaited.
Solved! Go to Solution.

You need an IOS of IP to IP Gateway for your router.
You just need to configure and allow connection of sip to h323 and vice versa in , " voice service voip " , and configure inbount/outbound dial peers.

Hi,
You will need an IP-IP gateway as stated above

This is a cutdown version of an IP-IP gateway however i hope it to be a good starting point for you.
