Hi everybody,

I am working on CUCM v9.1.2 architecture with the following configuration

CODEC :

- Intra-region 1 HQ : G711/G722

- Intra-region 2 RemoteSite : G711/G722

- Inter-region 1 HQ / 2 RemoteSite : G729

Phones :

6945 with SIP + "MTP required" Checked (option needed for security issue)

Media Ressources :

1) Gateway 2825 v15.1.4.M7 (CFB, MTP, XCODE hardware activated)

2) CUCM (Software Ressources on dedicated server "Cisco IP Voice Media Streaming App")

My problem :

  1. When I make a call between 2 phones on the same region, using G722, it's working fine with "MTP required" enabled : OK
  2. When I make a call between 2 phones both regions, using G729, it's working fine without "MTP required" enabled : OK
  3. When I make a call between 2 phones both regions, using G729, it's failed with "MTP required" enabled : KO

Gateway 2825 has the following configuration :

MTP dspfarm profil dont permit using g729 codec. This is normal?

Transcode should be used on the call 3), permitting call between 2 phones with g729 and g722 codec with "MTP required" checked?

Thank you for your help.

Resgards,

Pierre

Hi Pierre

I think your issue that you have to get other GW for your remote phones . I have two concerns on your Config:-

1-MRG for MTP or transcoded  when you created you have to select DP and the DP show have a RG which will be register to your CUCM. I think this is your problem.

2-The calls will be done if your configure between regions if your use G729 without any media resources.

If you need to test transcoding:-

1-For me i have HQ which connected to UCCX which uses g711 . When siteb call , the call failed so i configured transcoded and it solved my problem.

2-I have a CUE module on GW for SB when i get a call form HQ , the call failes and this because CUE uses G711 so when i configured transcoded for SB the call to CUE works.

Anyway your test is perfect but i hope to get other router for SB and do the below

1-DP for eac site and associate RG .

2-MRGL for each site , based on each site media resources.

3-For your test check the MTP required for the both sites and attach MRGL for both. I think in this way , it will work correctly.

Thank you

please rate all useful information

This is normal ?

When I answered, communication falied (bip bip bip)

With Wireshark, I have not RTP flow on phone 1 (erreur)

On Phone 3, I have RTP flow G711 with GW_2_RemoteSite (normal)

Any idea ?

Both phones communicate through MTP GW_HQ using G711

Problem : when running "show dspfarm all", none MTP resource are used on Gateway

   => This is normal ?

CALL # 2 :

Both phones communicate through MTP Gateway : Phone 1 used GW-RemoteSite (G729), Phone 3 used GW-RemoteSite (G711)

Have you an idea about comportment in CALL#1 (none DSPFarm resources used)?
