Hey I am facing problem in making few outbound calls simultaneously. I am executing "api originate" command from perl over ESL. After calling originate ,same perl file listens for CHANNEL_ORIGINATE CHANNEL_ANSWER CHANNEL_HANGUP_COMPLETE events. When perl file receives CHANNEL_HANGUP_COMPLETE event, it get terminates. I have done this code of originate & hangup listen event in perl cgi. When i do 10-20 request (10-20 simultaneous call), at freeswitch only 2-3 calls get serviced. To find out issue when i commented the code of event listen in cgi, i was able to make all 10-20 calls simulateneously. I have already checked apache configuration & is working well. Now i want to know whether freeswitch has limitation on number of clients listening to its events or there is some other issue of ESL. Please guide me what could be the issue. Incase of any further queries, Please feel free to mail me or contact me on the numbers provided below. Thanks & Regards, Chaitanya Bhatt Software Engineer. Viva Infomedia Pvt.
