Re: [asterisk-users] 911, location

[Shahnawaz Mir]

Thanks very much everybody who contributed their thoughts. I would try  
to get some DID's so that each physical location can be identified by  
911 call Center.

Re: [asterisk-users] PSTN to SIP line ratio

[Shahnawaz Mir]

Thanks Tim,

Your response is really helpful. Its not going to be very busy. I was  
expecting 10:1 but I will start some where between 4-10. Thank you  
very much.

[asterisk-users] PSTN to SIP line ratio

[Shahnawaz Mir]

Hi,

I am planning to deploy an Asterisk PBX for 100-200 users. I am not  
sure about PSTN incoming/outgoing line ratio for SIP users. I mean if  
you recall dial up internet the common line ratio is 1:10 (one line  
for 10 users on access server or an E1 for 300 users). Can somebody  
tell me what is the good ratio for incoming and outgoing analogue/ 
digital PSTN lines.

Regards

Smir
