[asterisk-users] asterisk pjsip as voip client with multiple registrations

[marek cervenka]

hi,

i want use asterisk+pjsip as voip client with multiple registrations 
(perf testing)

i'm using this example configuration for one account

[308]
type=registration
outbound_auth=308
server_uri=sip:308 at example.com:5060
client_uri=sip:308 at example.com:5060

[308](auth-userpass)
username=308
password=pass

[308](aor-single-reg)
contact=sip:example.com:5060

[308](endpoint-basic)
outbound_auth=308
aors=308

[308]
type=identify
endpoint=308
match=example.com


my problem is contact on the other side (is same for all endpoints)

Addr->IP     : 1.1.1.1:5060
Reg. Contact : sip:s at 1.1.1.1:5060

all incoming calls from PBX to my Asterisk are routed to only one 
account  (because of same ip address/port ?)

how can i specify different source port or different contact address for 
asterisk pjsip client with registration?
