Description: | I have a scenario where in channel SIP there are no users, only peers taken in realtime from a database. Also I am using multiple lines feature supported by Cisco phones 7960 and 7940. Multiple lines on a single phone mean that in my setup I can have 2 or more peers sharing the same IP address. When an INVITE arrives from one of IP sharing peers, chan_sip.c goes to function "check_user_full", where the code finds out that the caller is not a user (I do not have users) and gets down to call peer = find_peer(NULL, &p->recv); The second argument is the IP address where INVITE came from. Since there are 2 peers sharing this IP address, "find_peer" in 50% of the cases returns peer that is not the one that sent "INVITE". Eventually this means that is it impossible to place a call from one of the 2 peers sharing the same IP address. One possible way to get it fixed is replace the above line of code with peer = find_peer( (p->cid_num[0]=='\0') NULL ? p->cid_num, &p->recv); p->cid_num is populated just a few lines above in function "check_user_pull". Does anyone see that the suggested fix will create bug? If the suggested fix is not right way to do it then what is the right way? Thanks -c ****** ADDITIONAL INFORMATION ****** I can make a patch if the above is the right way to fix it. | ||

So make sure you have username= bkw By: Mark Spencer (markster) 2004-10-27 16:03:36 This is precisely what a user is supposed to be! Why aren't you using a user entry?
