Inbound SIP slow to connect

Hi all,

I am having an issue with inbound SIP calls connecting very slowly. After a call is initiated, it can take anywhere from 10-15 seconds to connect. In the IPIP Gateway (3845 Version 12.4(24)T6), I see the call hit immediately but I am getting a SIP 408 request timeout message after my gateway opens the RTP port and sends the invite. After the timeout, I see the ACK sent and the call proceeds normally. I have attached a debug highlighting what I'm describing. Any help with this would be greatly appreciated and please let me know if additional information is required.

Thanks in advance!

It was a dial-peer issue... Thanks for pointing me in the right direction!
