[cisco-voip] DSP allocation question

[Syed Khalid Ali]

Group:

I have the following scenario:
PBX_1--------G703/E1--------Router-A--------IP-WAN(g.729
codec)--------Router-B--------G703/E1--------PBX_2

What number of DSP should be populated in Router-A and B if E1 on PBX_1 and
2 is configured for 30 channels and total number of call over WAN should not
exceed 16. Codec used for VoIP call is G.729.

Syed Khalid Ali
