[Serusers] SIP UA ACK Timedout!

[Madan]

Hi,
I have been facing a strange problem of ACK Failed.
I m using SER with SJ Phone and Xlite as softphone to make calls..but after say 10-15 mins I m getting ACK Timedout! message on SJPhone..is this SIP UA bug or something to do with SER or config?

regards,
Madan
