no ip nat service sip udp port 5060

Thank you for the feedback, but I already was able to disable SIP ALG. The issue is with our VOIP system and I have been informed that SPI (Stateful Packet Inspection) may be the cause of our phone issues. I do not know how to check for this or disable it for the appropriate port.
