[Asterisk-Users] Cisco 7960 and short delay before voice star ts after ring.

[Bisker, Scott (7805)]

Adam,

Does Polycom license the SIP stuff from Cisco?  If not, then Asterisk may be the culprit, because all of my Polycom IP500s exhibit the same behavior.  I'm running asterisk 0.7.1, Zaptel CVS and libpri CVS both from a few days ago, but I don't recall having this problem a few months ago when I was running older versions.

Well I just took a look at the TAC case and things dont look good, seems the TAC are now blaming Asterisk for the problem but I will go through there debugs and push back, will let you know.

Thanks for the information.  You have saved me a few hours on the phone 
with TAC. <smile>

The issue is specific to SIP on 79xx phones, H.323/SCCP/MGCP all work fine. We're hoping to get a *special* release of the bug fixed SIP code for testing within the next 3/4 weeks. If we get it I'll post an update ...
