Re: [Serusers] ser+nat+siproxd+asterisk

IMHO, siproxd is not suited for a far-end NAT traversal scenario and certainly not capable of scaling if you have a large user community. It is suitable (and made) as a way to simplify traversal through firewalls in the corporate network and can be used standalone to handle mydomain.com calls (company internal and email-based calls). With ser, I assume it can be used to move the NAT issue from centrally managed closer to the user community. It may make sense to in some scenarios if the corporation is not ready to upgrade the FW to one with SIP ALG or upon up lots of ports. Summary: - If you are on the inside of the FW (i.e. you are the corporation), siproxd should do fine - If you provide services to the corporation and the ser is on the outside, it should be installed on a case by case basis (some FWs have SIP ALG already) - If you provide single user services and they happen to be behind corporate FWs, forget about siproxd g-) ----- Original Message ----- *From:* jeff kwong <mailto:kwongfucius@gmail.com> *To:* Serusers <mailto:serusers@lists.iptel.org> *Sent:* Friday, September 02, 2005 06:58 AM *Subject:* [Serusers] ser+nat+siproxd+asterisk Hi Guys! I just would like to share that I was able to get a working setup using SER as Softswitch, Asterisk as PSTN gateway and SIPROXD on my NAT Router. SIPROXD is an open source ALG and it effectively handles sip nat traversals. With it I dont have to run a seperate mediaproxy. When making calls from SIP UA to PSTN, RTP is as below: UA---NAT/SIPROXD---ASTERISK for 2 UA behind the same NAT: UA1--NAT---UA2 and for 2 UA behind different NATs: UA1--NAT1----NAT2---UA2 Thus there is less latency on signals and less traffic on SER. My question is, from the experience of other guys here, what do you think is the drawback or advantages of using SIPROXD together with SER to solve SIP NAT issues compared to other methods like using mediaproxy and rtpproxy?Will I still be able to do other SER features like accounting?
