I used to install the asterisk on centos 5 box, and has little experience with sipX. In this weekend, I installed the freeswitch on the same box, and have a test drive. Here it is couple of my questions. 1. it seems that both asterisk and freeswitch will use the same port (5060, I guess), so if I like to start the freeswitch, I must kill the asterisk, can I change the default port to another port. 2. follow the first question, can I use freeswitch along with asterisk, if I can, what may need to be taken care. 3. I saw the integration guide of "sipX and freeswitch", is this one work with the latest FS release. 4. If I like to use the FS library as the telephony layer for some other application, do you have the demo or samples, the closet doc I can found from your web site is the "embedded application guide". 5. currently, I am using the vbuzzer as the voip service provider, like to know if there is anyway to keep the same VSP, but switch from asterisk to freeswitch, if can, is there a "how to" guide, if can not with vbuzzer, is there any VSP who claim the support of the FS. Thanks in advance. Dave ___________________________________________________________ Sent by ePrompter, the premier email notification software. Free download at http://www.ePrompter.com.
