Hi, ---------------------------------------------------------------------------- ---- I am developing ASTERISK as my SIP Proxy server. So, questions arise when you begin adding new users, being like this, I would like to know if ASTERISK working as SIP PROXY has a limit of REGISTERS and if the answer is : YES this limit is caused by HARDWARE - NETWORK or else... I?m making this questions because I am facing some problems with my working ASTERISK and sometimes I got some informations associated to Sip Register informed below like: 1. UNREACHABLE or, 2. LAGGED and one of my most often problems is right after a communication is established, simply goes interrupted without any specific reason. So if someone from the list faced the same problem or have some usual information regarded to this subject that could help me solve this INTERRUPTED communications PROBLEM, please do it. Below my ASTERISK informations and HARDWARE either: Asterisk version is : ASTERISK CVS - 03/02/04 ----------------------------------- HARDWARE INFORMATIONS ----------------------------------- 1. Memory : 256 ddr pc 21000 2. Processor : 1.900 + Athlon XP 3. Red Hat 9.0 Jo?o Carlos Moura NiNeTel Telecommunications +55 85 264-9039
