If I remember correctly you should plan for 150bps of signaling traffic per phone.  I'm not sure about the voicemail question.  If Unity is at the main site then I don't think there is any traffic between the phones and Unity unless a phone is actively calling it.

Hi All,

We are planning to install SRST at branch office for 100 phones. SRST router has two T1 lines and route out bound call to PSTN from SRST router. We have 100mbps wide ether between main and branch office. I want to know how much WAN bandwidth I need for SCCP for 100 phones and 20 Voice Mail access. (These assume there is not extension dialing between two locations). I know Cisco bandwidth calculator but it is for VoIP calls but in my case I want to know bandwidth for SCCP and Voice Mail.

 

Thanks,

Manoj
