Symptom: MGCP-GW is always taking the respective static PT each time even though the CA sends a dynamic PT. This can be seen in the voip rtp packet logs. However, there is no voice-path issues. Conditions: Establish an initial call with PCMU. Then send a MDCX with dynamic PT for codec G.726-16 [or g726-32 or g726-24] The call is established successfully. But in VoIP rtp debugs its seen that static payload-23 is taken for G.726-16 is taken. The same behavior is seen for the other 2 flavors of G.726 - G.726-32; G.726-24 also. The regular mgcp configurations are done on the GW, no other specific configs.
