I currently have a ISR 2851 (old generation). I want to upgrade to a new generation 29xx series. However, I don't know which one to choose.
I saw a comparison chart and spoke to a Cisco Partner. They said I need to determine how many SIP sessions I want to support.
I am trying to find out how many I'm using now but not sure which command to use.

Here are my options for show sip-ua
show sip-ua ?
calls Display Active SIP Calls
connections Display SIP Connections
map Display SIP status code to PSTN cause mapping table & vice versa
min-se Display Min-SE value
mwi Display SIP MWI server info
register Display SIP Register status
retry Display SIP Protocol Retry Counts
service Display SIP submode Shutdown status
statistics Display SIP UA Statistics
status Display SIP UA Listener Status
timers Display SIP Protocol Timers
I ran show sip-ua connections but it doesn't look useful.
So I ran show sip-ua calls and this shows me all active calls. UAC and UAS. However, it shows detail info on all calls.
So I ran show sip-ua calls | in UAC|UAS and then added the two numbers. I believe that gives me the active calls.
show sip-ua calls | in UAC|UAS
SIP UAC CALL INFO
Number of SIP User Agent Client(UAC) calls: 8
SIP UAS CALL INFO
Number of SIP User Agent Server(UAS) calls: 3
I'm pretty sure UAC is outbound calls from my company out to the world. And UAS are inbound calls from the world into my company.

Is this the correct way of doing this or is there a better way?
