Hi Williams, Thanks for your email. Earlier message on the calling hq-phones was not enough bandwidth when i tried to place the call to 4220, after reload whole lab now its "Ring out" and fast busy. When i dial 4 digit extension of BR2 phone from HQ or BR1 phone call goes smooth no prob upto 4 calls after that , not enough bandwidth, Rerouting on display of phone and call goes via PSTN network I think this is expected ok This happens vice versa, sc to hq.
I configured sdspfarm transcode session 4 under telephony-service. my configuration is CME-SRST My problem is HQ and BR1 Phones can't call CUE VM Pilot . as mentioned above I am using RSVP, its configures exactly how you have explained & working ok. Automated Alternate Routing in Service Parameters = TRUE. HQ and BR2 you need to configure MTP resources = Done configure Location RSVP setting to mandatory between HQ -->BR2 = Done I have not configured ip precedence under sccp, does that matters, I have added now but situation remain same. i dont have serial uplink its ethernet only, but works as per my testing voice service voip allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip fax protocol cisco ! voice-card 0 dspfarm dsp services dspfarm ! interface Loopback0 ip address 172.16.30.254 255.255.255.0 ip pim dense-mode ip ospf network point-to-point ! interface FastEthernet0/0 ip address 192.168.1.4 255.255.255.0 duplex auto speed auto ip rsvp bandwidth 112 ! interface Service-Engine0/0 ip unnumbered Loopback0 service-module ip address 172.16.30.253 255.255.255.0 service-module ip default-gateway 172.16.30.254 ! interface Vlan31 ip address 172.22.30.254 255.255.255.0 ip pim dense-mode ! interface Vlan32 ip address 172.32.30.254 255.255.255.0 ! ! sccp local Loopback0 sccp ccm 172.20.10.12 identifier 1 priority 1 version 7.0 sccp ccm 172.20.10.11 identifier 2 priority 2 version 7.0 sccp ccm 172.22.30.254 identifier 3 priority 3 version 7.0 sccp ! sccp ccm group 1 bind interface Loopback0 associate ccm 1 priority 1 associate ccm 2 priority 2 associate ccm 3 priority 3 associate profile 3 register sc-conf associate profile 1 register sc-mtp associate profile 2 register sc-xcode ! dspfarm profile 2 transcode codec g711ulaw codec g711alaw codec g729ar8 codec g729abr8 codec g729r8 maximum sessions 4 associate application SCCP ! dspfarm profile 1 mtp codec g729r8 codec pass-through rsvp maximum sessions software 8 associate application SCCP !
