I am hoping this will find someone that has experienced issue before or has an idea where to look?
I have one site having call issues with SIP based calls, with the following conditions:
They will receive a call and only hear one way audio - but not all calls; and I triple checked all routings (across SDWAN, etc.)
-
They will call the number back in some cases and it comes back as number not in service?
-
They will call the number back in some cases and reach a caller that was not actually calling the location
-
They will call the number back and make a call that should have come in correctly
Here is the call flow:
Carrier.SIP > VGW in Data Center (San Jose) > CM11.0 > IPPhone.SCCP.7962 (Coachella) (all data traffic traverses SDWAN provided by same Carrier)
The only 'error' msgs I have on the local VGW at the site:
020276: Sep 28 11:23:11 PDT: %PLATFORM-4-ELEMENT_WARNING: SIP1: smand: RP/0: Used Memory value 89% exceeds warning level 88%
020277: Sep 28 11:33:21 PDT: %PLATFORM-4-ELEMENT_WARNING: SIP1: smand: RP/0: Used Memory value 89% exceeds warning level 88%
020278: Sep 28 11:43:31 PDT: %PLATFORM-4-ELEMENT_WARNING: SIP1: smand: RP/0: Used Memory value 89% exceeds warning level 88%
But my understanding is the local VGW does not take part in the call handling, despite being H323 VGW in CM11.
This client has 12 locations remote to the data center and they are all setup the same, but this is the only site reporting call issues.
Disclaimer - yes I am aware CM11 is no longer supported at Cisco - but this is what I have to work with. I'm frustrated and the customer is frustrated much more because this impacts business.
