[Freeswitch-users] CISCO SPA525G2 BLA issue

I am having inconsistent BLA issue on these phones, sometimes is works and sometimes not, this is what I have one of the lines set to: fnc=blf+sd+cp;sub=100@192.168.0.99;ext=100@192.168.0.99 This is my FS version: FreeSWITCH Version 1.9.0-582-c0a02f5~64bit the issue is on inbound calls, all phones are part of a simo-ring group, one person answers, the other phones sometimes show they are on the phone and sometimes not. Thank You, George
