             Summary: sip_to_pjsip script inproperly combines registration config
                 Key: ASTERISK-29470
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29470
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip
    Affects Versions: 18.4.0
            Reporter: N A


Major bug in this script, though probably minor overall as far as Asterisk is concerned:

the pjsip_to_sip script does not properly parse configuration where multiple registrations exist with the same server or provider.

This is example output from running the script - clearly nonsensical:

[reg_callcentric.com]
type = registration
retry_interval = 20
max_retries = 10
contact_user = callcentric
contact_user = callcentrict2
expiration = 120
transport = transport-udp
outbound_auth = auth_reg_callcentric.com
client_uri = sip:1 at callcentric.com
client_uri = sip:2 at callcentric.com
server_uri = sip:callcentric.com

[auth_reg_callcentric.com]
type = auth
password = t
password = f
username = 1
username = 2

[reg_freedid.ipcomms.net]
type = registration
retry_interval = 20
max_retries = 10
contact_user = ipcomms
contact_user = ipcomms2
expiration = 120
transport = transport-udp
outbound_auth = auth_reg_freedid.ipcomms.net
client_uri = sip:1 at freedid.ipcomms.net
client_uri = sip:2 at freedid.ipcomms.net
server_uri = sip:freedid.ipcomms.net

[auth_reg_freedid.ipcomms.net]
type = auth
password = 1
password = 2
username = 1
username = 2

The above is clearly nonsense, but PJSIP generates no errors from this configuration and one of the registrations will succeed, making it appear as though all is dandy when in fact most of the configuration is likely broken or non-existent as far as PJSIP is concerned.

This is created from the corresponding sip.conf:

register => 1:x at callcentric.com/callcentric
register => 2:y at callcentric.com/callcentrict2
