Blind transfer unsuccessful - W52P and Cisco Call Manager 9.1.2

[Yealink_Michael]

hi

thanks for your information

1. for this issue , as you mentioned , you are using platform Cisco Call Manager 9.1.2 , but the firmware you are using is 25.73.193.40, this firmware is just for Broadsoft platform !

so please upgrade to the newest commercial firmware and then test again , firmware download link :

2. as i can see from the trace file , the called in number is +61487892002 , it is a PSTN number right ? and it call to 72033 then 72033 blind transfer to 72038 , the process seems fine ! so is User B (72038) a yealink phone ? if yes , please provide the trace file of B ,so that we can confirm whether any INVITE is send to it , if no , then is it server side issue !

Note : all yealink phones , please using the commercial firmware but not Broadsofy firmware !

at last , for BEEP issue, did the W52P connect with a Reapter ? if yes , you can follow the guide attached to disable the verification tone !

if any update , please send us an email to support@yealink.com so that you issue will not be missed !

TKS & BR
