6921 while on hold cant take new call

[Marc El Achkar]

Hello,

I have a CME router 15.0<1r>M15

while calling from a 6921 phone, if i put the call on hold and i press the new call button i get : "Unable to create a call; the maximum number of calls for this line has been reached."

the config:

ephone-dn  26  dual-line

number 1501

ephone  26

lpcor type local

lpcor incoming PSTNTrunk

mac-address 34A8.4E61.76D9

max-calls-per-button 2

username "***" password 12345

paging-dn 50

type 6921

button  1:26

pin 12345

The 6921 phones have the latest firmwares 9.3.1.3

I have 7962 phones, when i put a call on hold ,new calls are working fine.

Hello,

I have this problem too. I have done tests and the issue is not associated to a firmware version. I have used serveral firmware for the phone a serveral version for CUCME (8.6 and 9.1). If you try to do a transfer you can make a new call. The issue is only associated to hold feature. I think that the phone by default set the maximun call per line to 1 but there is no way to set this value greater that one. The command "max-calls-per-buttton" has no effect. I have also reproduced the issue using sip firmware. 

Regards.

Dear Antonio,

Actually what i did to solve it , is to assign the 2nd DN on the phone any extension, in that way i managed to give it a new line. (For every 5 phones i gave the same 2nd DN)
