UCCE Mobile Agent - NO RTP

UCCE 9.0.4

CUCM 8.6

CVP 9.0.1

PSTN : SIP Trunk to CUBE and SIP trunk to Provider

 

Coonfigured IOS SW MTP and assgined it to MRGL.

Enabled MTP on - PSTN SIP trunk from CUCM to CUBE and also on CUCM to CVP SIP trunks

Assigned MRGL to these PSTN and CVP SIP Trunks as well

Configured LCP & RCP CTI Port, assigned this MTP MRGL, associated to pguser

Enabled MA on Desk Settings.

Agent logs into MA - nailed connection - I see 1 mtp connection in sh sccp connections

Caller calls in - MA answers - I now see 2 mtp connections in sh sccp connections

But NO RTP. same Codec class on both outbound nailed connection to MA, and incomg call from caller - set to use G711ALAW

Caller listens to a hiss, and a random click click all the time

 

Any Ideas / directions please?

 

Thanks & Regards,

Kartik Bhatia

You only need MTP checked on

You only need MTP checked on the egress trunk, no need for MTPs on the ingress leg from CVP/CUSP.  How are the regions setup in CUCM between the ingress and egress trunks?  Is this hardware/software/CUCM based MTP?  Does it work without an MTP?

When you look at the sccp connections do you see proper IP addresses? Do you see the same codec on all call legs?
