Yes, look:
netstat -nlp | egrep '506[01]'
tcp 0 0 192.168.0.177:5061 0.0.0.0:* LISTEN
13255/asterisk
udp 0 0 192.168.0.177:5060 0.0.0.0:*
13255/asterisk
Still, the problem is with *outgoing* *TCP* packets originated from
asterisk. Source IP is set to the first IP address of the interface only
when TCP is used. As I understand, the application (chan_sip in this case)
should request kernel to use the specific source IP address (used in bind
directive) for outgoing packets, however it seems to be done only for UDP.
For outgoing packets on TCP/5061 I see the following:
IP *192.168.0.172*.47596 > <mydestip>.5061: Flags [S], seq 2529313754, win
29200, options [mss 1460,sackOK,TS val 82765588 ecr 0,nop,wscale 7], length
0
And with UDP as transport:
IP *192.168.0.177*.5060 > <mydestip>.5060: SIP: OPTIONS ....
