Problem Description

Resolution

EM-27093

220111-407461

1

The WAN Side SIP messages stop being processed when multi-VLAN ALG is enabled.

TCP delay handshake fix was done for MVLAN scenario as well.

Workaround: Fixed a TCP handshake delay for multi-VLAN ALG configuration.

EM-27229

220215-557667

1

The mand process crashes when attempting to handle a SIP REGISTER message without a user name.

Added missing 'null' checks, and also made changes to return '403 Forbidden' for REGISTER without user info.

Workaround: A workaround is to use REGISTERs with user info only.

Resolved Issues - Severity 2/3

Issue ID	Case No.	Sev	Problem Description	Resolution
EM-27117	220114-408235	2	A memory leak occurs in the mand process if an invalid device-specific certificate is present.	Fix done for EM to switch to default cert in case of failure to load mac-cert. Workaround: Load a valid certificate to '/etc/certs/mac/em_mac_<mac-address>.crt'
EM-27118	210916-391637	3	The CAC counter is not cleared when using the Send-To URI function for serial hunting.	Fix done to remove the SIP call, even if there is no client found to map for inbound calls. Workaround: N/A.
EM-27119	210609-377107	2	Debugua Starts To Roll Over Logs at 4096 bytes and .old file grows more than the max-limit. The root cause is that there is an error in the roll-over logic, that caused the issue.	Fixed an error in the logic to clear the .old log file when the MaxSize is reached. Workaround: N/A.
EM-27120	211203-402745	2	The B2BUA serial hunt does not work when HMR and Send-To Trunking Device are both configured.	A new control handling the processing of HMR has been added. Workaround: To use the Send-To:URI option instead of Send-To:Trunking device.
EM-27205	220427-577261	2	The SIP Notify messages were getting a 481 error response during a subscription refresh operation.	When EdgeMarc sent a SUBSCRIBE refresh (relay or initiate a new SUBSCRIBE refresh), the previous dialog was deleted. Due to this any subsequent NOTIFY except during the first interval would be dropped with a 481 Transaction does not exist. Workaround: N/A.
EM-27225	220322-567208	2	The failure is triggered by the following sequence of events: On the LAN side, REGISTER messages with TCP transport were being sent to 5061 port of EdgeMarc due to a misconfigured phone. SSL drops the connection with 'SSL_ERROR_SSL' error message. On the WAN side of EdgeMarc with TLS, a large NOTIFY message with size (>4096 bytes in our test) is received. TLS thread detected SSL_ERROR in the error queue and hence failed to reassemble the fragmented NOTIFY packet. This leads to error condition when the message is read again. This will continue until the error queue is cleared.	The Edgemarc now immediately clears SSL errors from the stack thus preventing issues with processing subsequent TLS messages. Workaround: N/A.
EM-27235	220512-581005	2	Transferred call in Teams fails in cases with some Huawei phones due to an issue in the SIP SDP with the Huawei phones.	Adjustments to SDP processing were made to accommodate the issue . Workaround: N/A.
