SPA5xx Phone Lockups for BLF

pmoore

Level 1

Running 7.4.8 on both a 504 and 525 and have found that using BLF when more than 3 users configured completly locks up the phones when the notify is sent, if 3 or less users are contained in the notify then no problem , have a sip trace if required

It seems that, if NOTIFY is splited and whole UDP packet reassembling is impossible, phone hangs...

Same behavior in TCP.

Mark,

Did you ever get an answer to this from Cisco?

We have this fault logged with Cisco at present, awaiting confirmation from them.
