Polycom VVX line 2 not working with PJSIP

Asterisk Asterisk SIP
1

Ok so I know back in chan_sip if I had a phone with multiple lines I had to basically put something like, for the main line, register line 2. For instance if 302 was the main line and 303 was line 2 on the same device my chan_sip config would look something like this:

Note on 302 it has “register=303”

What is the PJSIP equivalent to this?

[302]
type=friend
host=dynamic
defaultuser=302
secret=xxx
context=internal-home
dtmfmode=rfc2833
canreinvite=no
callerid=302
insecure=port,invite
mailbox=302@internal
transport=tcp
force_rport=no
register=303
busylevel=4
call-limit=5
encryption_taglen=32

[303]
type=friend
host=dynamic
defaultuser=303
secret=xxx
context=internal-work
dtmfmode=rfc2833
canreinvite=no
callerid=303
insecure=port,invite
transport=tcp
mailbox=303@internal
force_rport=no
busylevel=4
call-limit=5
encryption_taglen=32

I don’t think the “register” option did what you thought it might do in chan_sip originally and likely did nothing. Have you tried just creating two normal endpoints with auth and AOR in PJSIP[1] and having the endpoint register each line to the appropriate one?

Yeah when I boot up the phone it’s like both endpoints come up but only for a few seconds, then the 2nd line goes down and never comes back up.

And what is the actual PJSIP configuration you’re using? For example in order to reuse TCP connections the “rewrite_contact” option has to be set to “yes”, otherwise Asterisk will try to establish a connection back to the device which does not always work.

5

Do I put rewrite_contact on the 302 extension somehow?

The rewrite_contact option is already present in both endpoints. You’d most likely next need to get a SIP trace using “pjsip set logger on” to see if that sheds light on the situation.

Turned out to be a NAT issue. Since they’re all on the same VLAN I just disabled the NAT stuff and it works.
