[Freeswitch-users] ptime problem with provider (Cisco hardware)

[Abdul Hakeem]

The pvalue of the originator overrides whatever you might have configured on
Cisco GW.

I am not a Cisco expert, but as far as I know packetization period is
configurable in Cisco. When you specify the codec for a dial peer, you can
set up the ptime value in milliseconds. This is an optional argument in the
Cisco command line and what happens when providers don't specify it is that
your end assumes a convenient or default ptime value, that probably don't
match with far end default... A solution would be to figure out what is the
convenient value for an individual provider and set up FS to match it, or
suggest your provider to specify a ptime in the first request.
By the way, Cisco supports 10, 20, 30, 40, 50 and 60 as ptime values for
codecs G.729, G.729A, G.729B and G.729AB.
