[SIPForum-discussion] To Develop SIP Server

[Mehrdad Nadooshan]

Hi Guys,

My name is Med. I have two questions for interested people:

1)  Recently I built a telephony system with OPENSIPS and ASTERISK as its media gateway. However, the SIP soft / hard phones are primarily behind NAT routers and firewalls. Moreover, there are many cases that there are more than one soft/hard SIP phones behind the same NAT. The basic solution I thought about was to use SIPROXD (to act as a sip proxy behind the NAT) and Interface with the external OPENSIPS. That way I can reach multiple SIP phones with no problems. Questions: First of all is this a reasonable most effective approach? Second, since I am compiling all these components from scratch the SIPROXD is giving me hell not finding the LIBOSIPPARSER.SO. It says there is no such file or directory. I've done many re-compiles of both SIPROXD and LIBOSIP2.SO and still see the same problem. My environment is CENT OS 5.3. Is there any environment variable that I need to miss or any link flags or .......

Any insights will be greatly appreciated. 


2) I am recruiting some real good developers for where I am at. Skill sets includes: SIP/Asterisk telephony, Linux and LAMP stack, Web Services and Database applications. Any combinations of the above will do. Full-Time position, great pay/benefit. I am looking for experience, creative, and highly enthusiastic people. Any one interested? If yes, please send your resume to me ASAP.

that's all

regards,
Med
