[Serusers] SER/NAT/PSTN/CISCO

Hi All, I'm a very "brand new" ser user and I'm tring to set-up a SER LAB. Now, I've successfully configured my server with RTP/NAT support but, what I cannot see is how to tell SER to cut off PSTN calls coming from my SIP clients. I also have a cisco 2600 and I would like to get SER be able to perform PSTN calls using it. I've seen and old post (http://lists.iptel.org/pipermail/serusers/2004-March/006722.html) on this mailing-list and so I would like to know if somebody could help me both with SER & CISCO config. Any help is very very very appreciated! Thanks in advance! _________________________________________________________________ Don't just search. Find.
