%SIP-3-INTERNAL: TCP_SOCKET_SEND_BLOCKED: connid= 1073, local_addr=, remote_addr=10.112.0.135, remote_port=5060 - All retries are exhausted, deleting pending messages
Has anyone ever seen this specific error before in syslog? I couldn't find anything related to it while searching.
Version is 15.4(3)M4

Thanks Manish.
Yeah I figured it was something of that nature. I believe the alert is actually legit tho probably why it is showing in this version.

This same error was triggered on one of my routers by having a misconfigured Inbound Calls-Calling Search Space in the CUCM SIP Trunk Configuration. The Calling Search Space was corrected and the error went away. Inbound call functionality was restored.

What solution did they give to this problem, the same thing happens to me now but with an ISR 4331 that I have installed in a remote site registered by SIP TRUNK to the CUCM at the headquarters.
I hope your valuable support

Hi ,
I also had a similar problem, what I did is I have removed the Keep-Alive command from the Dial-peer post that this issue was resolved.
