freepbx/Asterisk - phones restart randomly

Hi, I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox, elastix since 2007. I'm very new to the site so trying to bid as low as possible and get better reviews as much as possible. That being said I would like to have a little chat about your project to better understand the needs of the project regards,

Could please you logs when this issue happen , Logs are the key to find out what could be the cause.

Hello, The most common dropping calls come from NAT ( Network ). Sometime , you only have one-way call and call will drop in 10 seconds. If you server behind the firewall, please make sure open those port. 1: SIP : 5060 2. RTP port: 10000 - 20000 on your firewall. If you still got trouble, please contact me

Hi, I can help you with this problem. I've been working with asterisk since 2007, and with networking long before. Probably your problem is not directly related to asterisk, it could be an IP connectivity issue, an IP conflict or a NAT issue. I can take a look at the whole picture.

I'm a professional with experience of over 10 years in management of Linux platforms, information security, Cisco equipment, asterisk and web applications Certificates: ASTERISK DCAP, LINUX LPI, RED HAT RHCSA, CCNA and CCNP, CEH EC-Council

I have more than 7 years of experience in voip industry and I work in a voip based company which mainly runs on asterisk for delivering service to wholesale and retail customers. In your subject you have mentioned about the phone restarting randomly, but in project description, you have mentioned about call drops. Phone restart won't have any direct relation with asterisk box. Please give me access to find the exact problem.
